wls belong to the grnup of birds commonly referred to as raptors. In North America, there are 18 species of native owls, 11 of which are found in Maine. Of these 11, only three species-the barred owl, great horned owl, and Northern saw-whet owl-occur as common residents. And even with these species, detailed information on their abundance in Maine is lacking. In addition to the three common species, there are four winter visitors from the north that visit Maine. Of these, the snowy owl is most often seen; its large size and white plumage make this bird quite distinctive. The sighting of a great grey owl or a hawk-owl often creates a great stir of excitement

The fourth winter visitor is the boreal owl, which resembles a saw-whet in size but has a yellow bill and a spotted head. These northern owls visit Maine during periods when populations of their prey, namely lemming and voles, are low in their habitual range. This lack of prey seems to occur every four or five years. c::

Short-eared owls and long-eared owls are uncommon residents of Maine. The short-eared owl is a ground nester that prefers extensive open grassland with abundant populations of rodents. Conspicuous black patches on the underside of the wings of this owl distinguish it in flight. The long-eared owl is often found in coniferous woodlands, woodland parks, and sometimes small woodlots. It is similar in coloration and appearance to a great horned owl, but about half the size. The two owl species commonly found in warmer climates south of Maine, but less often in Maine itself, are the barn owl and the screech owl. The barn owl is also characterized by its long, sparselyfeathered legs. This owl is known to be especially prolific, having as many as 11 eggs in a single nest. Screech owls, the smallest of the "eared" owls, are the only owl with two distinct color phases, gray and reddish-brown. Furthermore, screech owls are closely associated with hardwood forests, which may be one reason why they may not prefer to nest in Maine. The status of these two owls species in Maine at this time is unclear; neither species has been known to nest in Maine in a long time. Department biologists and others, however, believe there is evidence to suggest that special management may be warranted. To this end, these two bird species have been nominated for "Species of Special Concern" status on Maine's rare bird list. Despite variability in abundance, owls display certain common but distinctive features and characteristics. Most owls in Maine are considered year-round residents, preferring to overwinter in Maine's sometime harsh climate. Owls resemble hawks, with hooked bills and powerful feet
with long, sharp talons specialized for grasping, killing, and carrying prey. They are in some ways different from hawks as welltheir soft, fluffy plumage, seemingly neckless heads, and forward-facing eyes. Unlike many birds, the female is larger in size and weight than the male. Owls are freeloaders when it comes to nesting, often seeking hawk, crow, or squirrel nests in which to place their eggs. In general, owl eggs are plain white; the normal clutch numbers from two to six eggs. Egg incubation in most birds begins after the last egg in the clutch is laid, but owls begin incubation after the female lays the first egg. Therefore, the hatching of young owls is staggered and unsynchronized, resulting in various sized fledglings in a nest. The male owl is a model father, assisting in the feeding of the young owls. The fledglings are rather slow to develop and have a long dependence on parental care-up to five weeks in some species. Both parents are often hostile and belligerent in defense ot their nest against intruders. There are numerous documented cases of humans being "dive-bombed" and
attacked by owls while climbing trees to examine nests. When disturbed by humans, owls will click their bills repeatedly in a distinctive manner. The flight of owls is silent, and most of them hunt at night. Those that feed in the daytime include the snowy, short-eared, and hawkowls. Owls exhibit a varied diet, most often feeding on whatever prey is most readily available. Research shows that many owl populations fluctuate in relation to rodent abundance. When food is lacking, some owls do not nest, or else their offspring succumb to starvation. Interspecies competition between owls may even result in large ow ls feeding on smaller ones. Owls seldom kill prey in excess of their immediate food needs. They swallow their prey in large chunks, digest the flesh, and then regurgitate the cleaned bones and fur or feathers in a pellet form. Owl presence can often be detected by an accumulation of these pellets and fecal splashing on the ground beneath roost trees, which are often used again and again. Although, like humans, owls have their eyes in the front of their heads, their eyes are in a fixed

position; they must move their heads for side vision. This binocular vision gives the birds the three-dimensional sight necessary for distance determination when hunting live prey. Unlike hawks, most owls are nocturnal. Owls' eyes contain more rods than cones, adapting them to acute night vision. Another feature that all owls have in common is their acute sense of hearing, also helpful in locating prey. Owls are difficult to observe because of their nocturnal activity. And in the daytime, they often retire to dense forest vegetation where they remain inactive. Fortunately for bird watchers, the shy and retiring owls tend to be vocal, particularly during the breeding ~eason, which begins in March for the great horned owl in Maine. Calling is part of the courtship ritual and facilitates the defense of the nesting territory, thereby restricting intruding owls. A reasonably good, human imitation of an owl call at dusk or ::? daybreak will often elicit an i" answer from an owl deep S in the dense forest. (Editor's note: see boxed item on page 5 for the pros and cons of calling owls.) The calls of Maine's three common ow1 species are distinctive and readily recognized. The barred owl calls frequently, and seems to say, "who cooks for you, who cooks for you-all?" The great horned owl's hoot or call consists of a series of consecutive "hoo-hoohoooo." The single note of the tiny saw-whet owl sounds somewhat like a saw being sharpened with a file.

The barred owl is a generalist in feeding habits, consuming a variety of birds, mammals, snakes, and insects. Unlike the other Maine owls which have light-colored eyes, the barred owl has dark brown eyes. Barred owls are often found near lakeshores or rivers and are also common denizens of cedar swamps, where they often prey on snowshoe hares. The smallest of our native owls, the saw-whet, weighs only four to five ounces! The saw-whet owl is the only owl with distinct immature plumage that differs from the adult feather coloration.

items in the diet of the great horned owl is the striped skunk, but this owl has been known to take even larger prey. During a wild turkey research project in Waldo County in 1987, a great horned owl was believed responsible for the deaths of two eightpound female turkeys, taken on successive nights out of the birds' night roost. The great horned owl is the first to nest in late winter.
saw-whets are a solid, not streaked, color, normally chocolate brown, with conspicuous white "eyebrows." The adult birds are light brown and streaked in appearance. Saw-whets prefer conifer forests, and often nest and roost in old woodpecker holes, but have also been known to nest in duck boxes. Department biologist Jim Dorso found a pair of saw-whets nesting in one of the hundreds of duck boxes he annually maintained. This particular pair of expectant parents (the eggs hadn't hatched yet) had caught several field mice and "stacked them up like cordwood" in a corner of the nest box, perhaps in anticipation of having several hungry mouths to feed. One management practice to aid owls involves the building and placement of owl nesting boxes to simulate natural cavities in woodland areas. Care must be taken to roughen the inside or to provide a wire ladder so that the young owls can climb up to the hole when
they are ready to leave the box. A horizontal sun perch near the entrance hole also enhances box usage. Owls have few enemies other than man. They are often harassed and pestered by crows, and some owls have been known to prey on other owls, as mentioned. In

can we do to help increase owl populations? Most importantly, we need to publicize the fact that all owls are completely protected by state and federal laws. Support of these laws and habitat protection by the general public is essential if owls are to flourish. •

To Call Or Not To Call Taped bird calls have long been used by bird watchers to attract birds that are elusive and hard to observe. Taped owl calls are not used just to attract and see owls, but to attract warblers and other songbirds that exhibit excited 'mobbing' behavior when the unseen predator is heard. This behavior gives the birdwatcher a good opportunity to see and identify a variety of birds as they home in on the taped call. As birdwatching increases in popularity, the ethics of using calls is being debated. People should not use tapes in popular or well-used viewing places; it is actually a violation to do so anywhere in a national park. These are some of the arguments for and against using tapes:
FOR: • tapes are the only way to see some species • attracting birds with tapes only distracts them for a few minutes and is less of an impact than tromping through their habitat to get a look • tapes shouldn't stress or impact birds because territorial defense (the birds' response to taped calls) is already a builtin part of the birds' behavior, and already 'budgeted for' in its time/energy allocation • if calls are played repeatedly to a certain population, the birds will learn to ignore the 'phantom calls' , with no long-term detrimental effect
AGAINST: • tapes are unnecessary; the same success seeing birds can be achieved through patience and persistence • dozens of people in the field playing taped calls exhausts, confuses, and distracts local bird populations • playing tapes agitates and stresses birds , keeping them from normal feeding , courting, nest building and care of young • if calls are played repeatedly to a certain population, the birds will learn to ignore the 'phantom calls', so taped calls become useless anyway

Here's the story of how fisheries biologists are bringing radio technology into play on Maine's largest river in an attempt to learn more about Atlantic salmon and what they go through on their awesome travels up and down river-and what we may be able to accomplish with what is learned from these "aquatic broadcasts."
The Penobscot River. mouth bass and chain pickerel, among other species, are known to eat smolts in rivers. A recent study by Oliver van den Ende, using a predictive model, esti-
mated that tens of thousands of smolts may be consumed by chain pickerel and smallmouth bass In the lower Penobscot River each spring during migration.
Once in the estuary, smolts encounter other predators. The few studies that exist tell us that predation by seals and cormorants (from offshore rookeries)

does exist, but it may not be as important as predation by marine fishes. Norwegian scientists estimated that 20 percent of the salmon smolts passing through one river estuary, and 25 percent passing through another, were eaten by cod congregating at the river mouths in spring. So, the smolt stage Is critical in determining how many adult Atlantic salmon will eventually return to spawn. To learn more about smolt migration In the
Penobscot River, we conducted studies in 1990 and 1991 using radio tags-small transmitters attached to smolts. These tiny tags were about the diameter of a cigarette and just over one Inch long. Tags were secured to the back of each smolt with suture material, inserted while the fish was under anesthesia. A thin wire antenna trailed -hind. Each tag was expensive (almost $200 each), and the battery lasted only about 17 to 20 days. So, it was impor-
tant to get the most information possible from the fish released. After recovering from the anesthetic, the smolts were released In groups of five on a weekly basis from April 13 to May 18, 1991. Each tagged fish was stocked by hand In the Penobscot near Howland, about 57 miles upstream from the river mouth. Tracking was the exciting part of the study. Once released, most smolts moved rapidly downstream. in 1900, we attempted to follow the young fish with specialized radio receivers and antennas mounted in boats. But, the fish were too fast. They easily outdistanced the boats and, only by following along the shore in trucks, using mobile receivers, were we able to make contact, in 1991, we were much more successful. We used smaller tags and tracked fish using airplanes. Again, smolts moved downstream very rapidly, but observers in the airplanes were able to

Radio tag used with Atlantic salmon smolts (compared to an average pocket knife for size). accurately plot locations of the smolts and the rates of movement One fish, released on April 13, moved three miles downstream in the first hour! We found that smolts averaged four miles per day during their migration, but it wasn't one continuous trip. Most smolts alternated periods of active downstream movement with a day or two when they were stationary. in most cases, these inactive periods seemed to be resting pauses as the fish moved downstream or interruptions when salmon seemed to be reorienting themselves to the flow of the river. When they decided to move, however, smolts were very fast, travelling at an average speed of over 9 miles per day. Few fish were tracked farther than 25 miles downstream,
which may have been due to one of several factors. first, the batteries on the radio transmitters may have died, in which case fish may have continued their downstream migration undetected. Second, smolts may have simply stopped migrating. We do know that some hatcheryreared smolts never do migrate to sea. We also found that, after mid-May, few of the radiotagged smolts moved below Howland. Third, smolts may have been eaten by birds, fish, or mam-
mals. The peculiar tracks of several of the salmon suggested that, when passing through or holding in slower portions of the river, they may have encountered predators. Because of this potential mortality, current studies of predation on smolts all the more important. Within a few years, scientists working on the Penobscot River and the Connecticut River, in southern New England, may be able to shed more light on the gauntlet of predators that Atlantic salmon encounter on their long, difficult journey to the sea. â&#x20AC;˘

We'll Be Hatching by Steve Wilson Photos by Lisa Kane

n the ballot this November, along with many, many office races and other considerations, will be a proposal for a $10 million bond issue for Maine's fish hatcheries. The bond issue emerged from the Appropriations Committee with a unanimous "ought-to-pass" recommendation, and has the vocal support of many of Maine's sportsmen. Since the late 19th century, the department has been actively involved in the rearing of game fish to support fisheries management programs. These programs have resulted in the establishment of landlocked salmon, brook trout, and a variety of other species in more than 200 waters throughout the state. The annual production of fish from the department's fish hatcheries continues to play a vital role in the maintenance of inland fishing opportunities highly valued by Maine anglers, as well as the thousands of visitors who come to Maine each year to enjoy the state's outdoor heritage. More than 68 percent of the state's landlocked salmon waters have inadequate spawning habitat and are maintained by stocking. Likewise, many waters do not support wild self-sustaining populations of brook trout or lake trout; these waters are entirely supported or substantially augmented by hatchery trout stocking. Many waters that require stocking are located near population centers; these management programs are the result of efforts to bring angling opportunities closer to the public. Currently, the department stocks 1,500,000 fish annually in waters across the state, thus creating fishing opportunities that would not otherwise be available. Most of Maine's nine fish rearing facilities were built in the late 1930s and 1940s, with the newest production facility constructed at Enfield in 1959. Over the past 20 years, the department has not had the funds needed to keep pace with the ever-increasing maintenance needs associated with these aging facilities. If this situation continues, five of the nine facilities are likely to be inoperable or have their production severely curtailed in the near future. This would include loss of entire programs for brook trout, brown trout, and splake, and up to a 50 percent reduction in the landlocked salmon program .

The economic impact of Maine's inland sport fishery has been studied by Kevin Boyle , a resource economist from the University of Maine's Department of Agriculture and Resource Economics. Based upon the results of a survey of fisherman in 1989, Boyle estimated the economic impact of Maine's inland sport fishery to be at least $160 million per year. At least $40 million of this was generated by nonresidents. Hatchery fish currently provide 40 percent of thC' coldwater fishery in Maine lakes and ponds and are crucial to maintaining the economic benefits derived from these resources. The loss
Wade Hatchery Casco
The Wade Hatchery is where the world famous Sebago landlocked salmon is raised and distributed to the southern, western and central parts of the state. Half of the landlocked salmon stocked in the state originate from this vital facility. The water supply comes from a single 16" pipe from Pleasant Lake. Typically all eggs come from "wild" adult salmon trapped in the fish weir at Jordan River (Panther Run) a tributary of Sebago Lake. Needed improvements are: another intake line to increase water supply; a micro-screen filtration unit to remove silt, debris, and possible pathogens ; a water effluent treatment system ; more fish rearing units to increase production ; repair of deteriorating raceways.
Some Plans! of the department's fish rearing capabilities would result in at least a $50 million annual reduction in these economic impacts from fishing . The funds from this bond issue will provide the monies needed to overcome a large number of problems that are impacting the production of fish needed to meet the department's stocking needs, but will also result in a 25 percent expansion in fish production-nearly 400,000 fish per year! Increased production capabilities will allow initiation of a rainbow trout program, to be stocked pri-
marily into selected rivers and streams. In addition , the department will be able to establish a restoration program for lake whitefish , and to raise American shad fry in support of Department of Marine Resources shad restoration initiatives on the Kennebec River. In a letter to us recently, former Maine Fish Pathologist Peter Walker attempted to explain his feelings about the special niche that fish hatcheries occupy in the scheme of things. Walker said that "hatcheries that have remained open into the 1990s are particularly valuable
Ela Fish Rearing Station Embden One of two rearing facilities operated by the hatchery section, this station receives brook trout and landlocked salmon from sister hatcheries and raises them to stock in waters of central and western Maine. Because of its superior and abundant water supply from Embden Lake, this facility would be a prime candidate to expand into a fully functioning hatchery. This would entail expansion of the water intake system, instaUation of a micro screen filtration and ultraviolet purification system to remove debris, parasites, and pathogens; providing oxygen supplementation , constructing an egg/fry rearing building , adding more fish rearing units, and repairing deteriorating or damaged raceways .
Dry Mills Hatchery Gray One of the oldest and perhaps the best known Maine hatchery, the Dry Mills Hatchery is adjacent to our Gray Gamel Farm & Visitors Center. This facility is the Department's premier brook trout hatchery, raising exceptional brook trout and lake trout to stock the southern and central section of the state. Fry are also raised for transfer to sister rearing stations. Some of the needed improvements are: further development of well water sources to enhance growth rates of fry; a micro-screen filtration to cut silt, parasites, and pathogens; repair of raceways ; development of a public education facility.

state resources. Their survival means they have been able to withstand the scrutiny of auditors; that in turn means they have been able to produce fish of the species, quantity, and quality that the public demands at a reasonable cost. These are resources to be protected and cherished ."
Phillips Hatchery Phillips
This hatchery's contribution to Maine's fisheries is valuable far beyond mere stocking totals. Until the late 1960s, more than 80 percent of brook trout fry hatched in Maine hatcheries died from infectious pancreatic necrosis (IPN). Then, thanks to the insight and foresight of then Fish Pathologist David Locke (recently retired as Superintendent of Hatcheries), Phillips was depopulated, disinfected, and reopened as Maine's diseasefree brook trout broodstock facility. Situated in a heavily wooded valley along the old bed of the narrow gauge railroad between Farmington and Rangeley, Phillips has produced several million certified virus-free brook trout eggs for Maine's hatchery system each year since the late 1960s. All the brook trout stocked in Maine originate as eggs from this hatchery. Maintenance needs include: increase the water supply to enhance the rearing environment; repair damaged or deteriorating raceways ; increase egg-holding capacity; install an oxygenation system; install a water discharge treatment unit; cover raceways to prevent predation and improve fish holding conditions.

During an interview for a Bangor television station around 1982 or 1983, the reporter must have thought Walker was a little too enthusiastic in his praise of Maine fish culture. Off camera, he asked him: ''Truthfully, how far ahead of other states are these guys?"
Cobb Fish Hatchery Enfield
This is one of our most versatile hatcheries, due to its high-tech water purification system and two-pipe water supply running from Cold Stream Pond. The supply is plumbed in such a way as to allow independent temperature control in each of six different lines of raceways. This versatility has made the Enfield Hatchery an ideal facility for fish culture and fishery management experimentation over the years. As needs have changed from year to year, so has this station's production. Cobb typically produces large numbers of landlocked salmon and brook trout that are stocked in eastern and northern Maine. Maintenance needs include: a water effluent treatment system ; repair of raceways; repair of ultraviolet/filter building; construction of a public education facility; adding fish rearing tanks to increase fish production, and repair of deteriorating or damaged raceways.
Light years," Walker answered. And he says it's still that way to this day. The 1989 Boyle economic survey of fishing and hunting stated that expanded fish production of the type being discussed here would conserva-
tively increase Maine's economy by $15 to $20 million. Simply maintaining existing fish cultural facilities will prevent the loss of $50 million to the state's economy! The department strongly believes that a $10 million investment in Maine's sport fish hatcheries would result in a
Palermo Rearing Station Palermo The Palermo Rearing Station , located on the outlet of Sheepscot Lake near the intersection of three counties, receives its brown and brook trout from sister hatcheries to raise and stock in the central and eastern parts of the state. Like the Ela Station, Palermo has a superior water source, fed to the station by a dual warm and cool pipe system. This allows for maximum water temperature manipulation to create optimum growing conditions. This would be another ideal station to develop into a full fledged hatchery facility. This would require installation of a micro-screen filter and an ultraviolet purification system to eliminate possible parasites and pathogens; build a hatchery structure to r~ar eggs and fry on site, add fish rearing units to increase fish production and a public education facility.
Grand Lake Stream Hatchery Grand Lake Stream This hatchery is situated along the east bank of one of eastern Maine's most famous landlocked salmon streams. Despite the shallowness of the unit's single intake pipe in nearby West Grand Lake, the steady 2,000 gallons per minute flow stays cool enough throughout the summer to rear a healthy crop of the renowned West Grand strain of landlocked salmon . This was the first Maine hatchery to have a modern pretreatment system installed on its water supply, about 21 years ago. This virtually eliminated serious infectious diseases at this facility. Grand Lake Stream Hatchery also supplies eggs and fingerlings to sister hatcheries to stock throughout Maine. Much needed maintenance needs are: develop a well water source to accelerate development of eggs and fry ; replace old micro-screen filtration and ultraviolet purification units; provide water effluent treatment; repair deteriorating fish rearing tanks; add new rearing units to increase production.

In this article, we acquaint you with each of the nine fish culture facilities , then give each one its own special character, and finally give you a glimpse-station by

And as the future of fish culture and stocking programs goes, so goes a significant part of â&#x20AC;˘ sportfishing in Maine.
New Gloucester Hatchery !Yew Gloucester This is the last survivor of the many fish production units constructed across Maine in the 1930s by the Civil Conservation Corps. Despite the best of intentions, most of those facilities, constructed almost entirely by hand labor during FDR's administration , were built on small or unreliable water supplies which proved unable to produce fish consistently or economically. But not so the New Gloucester unit. Its spring-fed brook water supply and primitive but effective earthen raceways have turned out the bulk of Maine's brown trout production for some 56 years, justifying many times over the rather meager original investment. Planned modernization of the facility may insure New Gloucester's continued participation in Maine fish culture for years to come. Much needed repairs are: repair dam/reservoir that is current water feed; develop water supply; build new hatchery complex to increase production and install modern round fish rearing tanks to replace the earthen raceways.
Governor Hill Hatchery Augusta Located within the city limits of the state capital and situated on land bequested by the late Governor John F. Hill, this spring-fed hatchery is the source of the department's lake trout program and a major brood trout incubating facility. In addition , it is the hatchery responsible for producing the department's splake program , an increasingly popular lake trout/brook trout hybrid. Desired improvements include : development of wells to increase the water supply, installation of new brood fish holding units to free up raceways for increased fish production , and installation of a micro screen filter and reservoir covers.

Mallards Featured on Maine Duck Stamp An Ellsworth-area woman has won the 1994 Maine duck stamp competition with an acrylic painting of a pair of mallards. Susan Knowles Jordan, 33, of Waltham took top honors in the contest, entered by 42 Maine artists all painting the same species of waterfowl. Jordan's painting will be reproduced on Maine's 1994 migratory waterfowl conservation stamp, better known as the "duck stamp," available to hunters and stamp collectors beginning in September. Contest runner-up was Michele Witham of East Millinocket. Honorable mentions were won by Donna Chase of
Patten, Patti Carter of Brunswick and Rick Alley of Islesford. Judges were Jeannine Staples, who won the contest in 1993 and cannot enter for two years; C .. D. Armstrong, chairman of Maine Ducks Unlimited; Jim Perry, founder and director of the Talent Tree Art Gallery in Augusta; Mal Coulter, a wildlife biologist and retired chair of the University of Maine's Wildlife Department; and Norm Trask, deputy commissioner of the Department of Inland Fisheries and Wildlife. This year's was the seventh duck stamp art contest, each featuring a different species of duck or goose native to Maine. Four previous stamps were com-
missioned to nationally prominent waterfowl artists. Jordan, an Ellsworth High School graduate, is primarily a self-taught artist, focusing most of her painting effort on wildlife art. In 1992, the first year she entered the duck stamp art contest, she won an honorable mention. Her 1993 entry earned runner-up honors. The Department of Inland Fisheries and Wildlife uses income from sales of the $2.50 stamp to buy and manage waterfowl habitat in Maine. The winning artist receives a cash award of $1,000 and a sheet of stamps reproduced from her painting. â&#x20AC;˘ Summer 1994

Fighting For Maine's esou es Council of Maine Outdoor Future by Robert Kimber
The
Natural Resources Council of Maine (NRCM) celebrates its 35th birthday this year and is going stronger than ever. The Augustabased organization describes itself as a "nonprofit, independent citizens' organization dedicated to protecting Maine's environment through a program of advocacy, education, and legal defense." That modest self-definition is accurate enough, but it is a bit too abstract and bloodless to convey the fire, energy, and vision that have characterized the Council ever since its inception. NRCM' s founders were outdoorsmen who had fished the rivers and roamed and hunted the woods of Maine most of their lives and were appalled at the environmental degradation they were seeing in the rnid-50s. In 1954, Jim Briggs of Caribou, an outspoken firebrand who was way ahead of his time, ran for the state senate on an environmental platform and
Maine 's North Woods, 10.5 million acres in all, is the largest undeveloped forested area left in the eastern United States. The Natural Resources Council of Maine is working to protect the fish and wildlife and scenic beauty of this vast area for future generations.

won an upset victory despite the opposition of local industrial interests. "Pollution was so bad," Briggs observed, "that folks in Presque Isle had to come to Caribou to take a shower." Sparked by Jim Briggs, the NRCM was officially constituted in 1959 with Bob Patterson as its first president. Not surprisingly, rivers and water quality issues were among NRCM's first priorities; from that day to now, a river has run through the Council's history. If that were not so, the map of Maine would doubtless have suffered some changes that no angler, canoeist, or river lover could have witnessed without a heavy heart. During its first six years, the council took the lead in developing a plan for the Allagash River, which was then threatened at the same time by increasing road access and, even more seriously, by a federal hydroelectric project which would have flooded the Allagash valley. The happy ending to this effort came when Maine voters overwhelmingly approved the creation of the Allagash Wilderness Waterway in a 1966 referendum led by NRCM. Thwarted on the Allagash, the Army Corps of Engineers turned to the Dickey-Lincoln hydroelectric project which would have dammed the St. John River and inundated the longest stretch of wild river remaining in the eastern United States. Again, the Council took a lead role, this time preserving the free-flowing St. John. The group was the most outspoken advocate for the 1983 Maine Rivers law, which provided permanent protection for river segments with outstanding fisheries, boating, scenery, and scientific interest while permitting development on less valuable segments. The most dramatic river campaign of the 1980s was the Big A controversy. In this case, as in those

previously described, the council, in cooperation with the Sportsman's Alliance of Maine, Trout Unlimited, and other conservation groups, acted to save one of the prime whitewater runs in the Northeast and the Big Eddy landlocked salmon fishery from hydroelectric development. Currently, the Council is working to remove the Edwards Dam in Augusta and restore 17 more miles of the anadromous fishery the Kennebec River once supported above the present dam. Just as high on the Council's agenda as the preservation of free-flowing rivers is the quality of Maine's waters. In the 1960s, when many of our rivers were still dumping grounds for municipal sewage and industrial effluents, the Council led a successful campaign to clean up Maine's rivers. Our eyes and our noses tell us that we enjoy vastly improved water quality today. However, toxic
In 1966, the Natural Resources Council of Maine led a successful statewide referendum campaign to preserve the Allagash River, one of Maine's most spectacular treasures. The Allagash is now protected forever from dams and development. Pictured are Allagash Falls, near the river's confluence with the St. John River. pollutants we cannot see, smell, or taste remain in our waterways. Dioxin, a highly toxic byproduct of the chlorine-bleaching process used in many paper mills, accumulates in fish, making them a health risk to eat. The Council has urged paper mills using chlorine bleach to switch to a chlorinefree process, and it also drafted and supported legislation to establish a water-testing program that will let scientists gather precise information on Summer 1994

CAN FISH SMELL? Chemicals that you would sniff in the air are also carried in water. The senses of smell and taste are similar in fish; both senses detect these chemicals through a process known as chemoreception. (key-mowre-SEP-shun) In trout and salmon, smell chemoreceptors line the pits inside the nostrils. Taste receptors are clustered on the head and in the mouth. Scientists believe that salmon and sea trout use chemoreception to return to their birth rivers to spawn .

A health issue comes to light. The presence of questionable levels ( fresh waters is a situation sadly not unique to Maine. Other states ~ similar testing in recent months. This article will hopefully answe~ put the Maine test results into proper perspective. "Pregnant women, nursing mothers, women who may become pregnant, and children less than eight years old should not eat fish from Maine lakes and ponds. Others should limit annual consumption of fish from Maine waters as f vllows: those who eat large (older) fish should consume no more than six fish meals per year, while those who limit themselves to eating smaller (younger) fish may consume up to 22 fish meals per year." From a statement issued jointly by the Maine Departments of Human Services, Environmental Protection, and Inland Fisheries and Wildlife
What are the health effects of mercury? Organic mercury can have toxic effects on the nervous systems of developing individuals (unborn and young children) and on the nervous systems and kidneys of adults, depending on exposure. Children from prenatal to seven years of age are more sensitive to mercury than are adults because of the developing status of their nervous systems.
Is there a problem with swimming in Maine waters, or any other problems associated with this contamination? There is no health risk related to mercury from activities such as camping, swimming, boating, or fishing (and releasing) in Maine waters. Handling fish will not expose anyone to elevated levels of mercury. The state continues to encourage the general use of Maine's freshwaters as healthy and enjoyable forms of recreation. Catch and release, particularly of larger or older fish, is a good way to continue to enjoy fishing, improve fish populations in Maine, and still avoid eating contaminated fish.
risk of mercury-related adverse health affects. The risk is low, even with these very sensitive populations, but caution is advised if any high risk person is involved.
Do other states in this area also have a problem? Yes. All the New England states that have tested for mercury in their freshwater fish have detected elevated levels. More than 30 states, including most of New England, have issued health advisories and/ or posted warnings concerning mercury-contaminated fish.
If fish from a specific lake have not been tested, is it possible to get such fish tested? There are no state resources at present to pay for additional testing of fish. Any individual or group, however, may arrange for private testing .
Will there be changes in this advisory as more information becomes available?
contaminated fish?
Yes. Public health advisories are based on the most current information available, and will be updated as more information is obtained. Data from this mercury study, along with data expected on other contaminants, will be analyzed during 1994. A new advisory will most likely be released before the 1995 fishing season.
No, at least not for the general population at the levels detected in Maine's freshwater fish. Those with developing nervous systems (children up to seven years old, pregnant women, women who may get pregnant, and women whe are breast feeding), however, are at higher

Were the fish which were tested for mercury also tested for other substances? Yes. Other substances for which tests were performed include cadmium, lead, DDT, PCBs, and several commercial pesticides. Results are expected in the fall.
Does this warning apply to river fish?
dental fillings), as inorganic mercury (most commonly used in manufacturing), and as organic mercury (used as a pesticide, this is the form usually found in contaminated foods). The element changes from one form to the other in the environment and in the human body (aided by bacteria). In high enough doses, all three forms present serious threats to human health, but organic mercury (especially methylmercury) is a serious threat to human health even at much lower doses.
Although only a limited number of Maine's river fish have been tested for mercury, it is likely that many large river gamefish may also contain high levels of mercury. There is an existing warning for dioxin which advises pregnant women, nursing mothers, and women who may become pregnant against consumption of river fish caught in Maine's three largest rivers.
Does this warning apply to fish caught in salt water off the Maine coast? No. Saltwater fish were not tested in this study. While there is some mercury contamination of tuna, this problem is currently regulated by national programs.
Why is mercury in our Maine environment? While mercury is a natural component of the earth's crust and sediments, it has also been used in various forms in medicine and industry for 3,000 years. Although most medicinal uses have now stopped and pesticide use is rapidly declining, industrial use of mercury continues. Burning of fossil fuels, particularly coal; disposal of mercury-tainted solid waste in landfills; municipal waste incineration; application of mercury-containing points, fungicides, and pesticides; and combustion of waste oils-all these contribute to increased mercury levels.
How did mercury get into Maine's freshwater fish? Any mercury released into the environment may be changed to its organic form and concentrated in the fish. In the past, some industries discharged mercury directly into Maine waters. Although such discharges have now ceased, quantities of this mercury remain in the environment and can be accumulated by fish. In addition, mercury emitted into the atmosphere (such as by burning coal or garbage) can be transported long distances and deposited in remote environments. Although the amount of mercury is small, it is sufficient to account for the levels found in Maine's fish.
Have fish from all Maine lakes and ponds been tested for mercury? No. In the most recent study, 127 lakes and ponds were statistically selected at random from approximately 1,800 lakes and ponds that have been surveyed by the Department of Inland Fisheries and Wildlife. There are also results from other studies on roughly 30 additional lakes and ponds from this same surveyed group of 1,800. There are about 4,000 smaller ponds in Maine that have not yet been surveyed. There is reason to believe that mercury levels in fish from other as yet untested Maine lakes and ponds are similar to those found in our sample.
How was this problem with mercury in fish discovered? We had limited data on mercury levels in Maine's freshwater fish from earlier studies, but the first comprehensive study conducted in Maine was the "Fish Tissue Contamination in the State of Maine Project" under the Environmental Monitoring and Assessment Program (REMAP). For this project, fish were collected in 1993 by the Department of Environmental Protection (DEP), the Department of Inland Fisheries and Wildlife (DIFW), and the EPA. The contaminants were analyzed by the Maine State Health and Environmental Testing Laboratory in Augusta and the National Biological Survey's National Fisheries Contaminant Research Center in Orono.
Why aren't lakes being posted to warn people about the mercury contamination? Fish contaminated with high levels of mercury were caught in a large number of the lakes and ponds sampled. The general advisory provides the warning necessary for all these lakes. At this point, a posting would only provide an extra warning to those who might not hear or read the general advisory. There is also the risk of creating a false sense of security. Some people might mistakenly think that only posted lakes have fish contaminated with mercury, when fish from non-posted lakes may in fact have similar levels as those in posted waters.
Is there a way to reduce or eliminate mercury in the fish through cooking or other treatment? No special cleaning or cooking method will decrease mercury in fish. Mercury is stored in the fish fillet or muscle portion of the fish, not in the fat, so removing fat, skin, or other parts from the fish will not lower mercury levels. Summer 1994

There are admittedly scores of uses for monofilament fishing line-it's handy stuff to have around! But please be careful with it. This house sparrow discovered one characteristic of this product which we seldom consider-its deadliness! Wrapped in a snarl of discarded line, presumably becoming more and more entangled with every minute of struggle, this creature finally strangled itself (it appears). Or maybe it swallowed a tangled knot of line, or starved to death. Whatever the cause of death, and however small the species involved, this would not have happened if this line had been discarded in the proper manner. Even the biodegradable line, so-called, designed to disappear in a relatively short time, still has plenty of potential for this kind of situation while it's still around! If you 're finished with it, bring it home and dispose of it properly. Our " throwaway" mentality has caused a growing problem over many years. And if we 're now coming to grips with it, let's confront ALL of it, not just the "big" issues!

LETTERS TO THE EDITOR Dear Sirs: What a grand idea and what an interesting article! I do hope you find more in this series(?) Just this week I had seen one of the original posters (Gee Mister!) so I could not resist your offering. It was so nice to hear that some of the Maine agencies can work together. My hat is off to you and the museum people who are doing a splendid job of which your cover can attest. Sincerely, Carol Young P.S. The whole Spring Issue of Me. F & W was especially nice, I thought!
Gentlemen: The cover on the spring issue of the magazine is just out of this world! The p icture of the little boy wistfully wondering if there will be any fish left when he grows up is right from the heart. I have seen this poster on display in the fishing department at L L Bean's in Freeport, and have wondered how to get a copy, bu t have just put off doing something about it. And so here it is in our magazine. I have called and requested an extra copy of the magazine, and would like to order two of the reprints of the poster. My check for $10.00 is enclosed. Thanks for the great job in tracking this down, and I wish you success in locating others in the series. Sincerely, Dean S. Jordan Retired Warden
Dear Sirs: We were quite interested in your article on the "Gee, Mister!" poster and available reprints. We're afraid we won't be requesting a reprint, though, as we have one of the originals! We own and operate Frost Pond Camps above Ripogenus Darn and are currently in the process of dismantling our large old barn, built not long after the darn was completed and the orad was pushed through to Frost Pond. The "Frost Pond Storehouse" was probably built in 1919, according to a date found on one of the beams. Our poster, which was covered by cardboard, certainly isn't in the good shape of the copy shown in your photo, but it's quite intact and legible, except for some mold. We've cleaned it up, ironed it flat, and plan to cover it with clear contact paper and display it. We discovered

it practically as soon as we discovered your article. We believe we may have found, and sold to an antique dealer (alas!) another "Gee, Mister" poster a number of years ago, because when we discovered this latest one and read your article, the poster was familiar to us, and we know we sold two posters about four or five years ago. One of the two we are certain we sold was a rather gruesome poster of about the same size as the "Gee, Mister" poster, but that one portrayed a very dead hunter with blood flowing copiously (and in red) from a head wound, while another hunter looked down with horror on his face and (I believe) smoke still wafting from his rifle barrel. I'm afraid I can't recall what words were on the poster - maybe none; words were scarcely necessary. While dismantling our barn, we also salvaged a smaller poster, about 11" x 14", in black and white, which has no picture but says, "REMEMBER: Perpetual CLOSED SEASON on MEN." They really made good posters back then, didn't they? We cleaned this one up and covered it with contact paper, also. We hope this adds a little more interest to the topic of old posters, although we suppose it does not actually provide more enlightenment to the background of the "Gee Mister!" one. We enjoy reading Fish and Wildlife. Thanks! Sincerely, Frost Pond Camps Judy Givens P.S. My daughter tells me the "dead hunter" poster said, "Look Before You Shoot." From The Editor: Thanks fo r all your nice comments regarding the poster effort. We couldn't resist re-issuing this message to today's anglers. As the letter above states: "11zey really made good posters back then, didn't they?"
