Summer Fishing Update

Three events and their potential impacts on this year’s salmon fishery

Show each will play out, and what the cumulative impact on recreational salmon angling and salmon recovery will be.

Mark Selective Fisheries Approved

So far, 2023 has been confusing and frustrating, yet potentially beneficial for BC’s marine recreational anglers. Three seemingly unrelated events are influencing this uncertain environment. However, no one knows exactly

After multiple frustrating years of rejected fishing proposals, a few modest mark selective fisheries (MSF) have been approved in important angling areas. Mark selective fishing depends on marking enough hatchery reared salmon, usually chinook and coho, so they can be retained by fisheries.

BY TOM DAVIS Stephen Johnston

All unmarked salmon are considered wild and must be returned to the ocean, where they hopefully survive to spawn thereby contributing to weak stock recovery.

The standard mark for a hatchery salmon is a clipped adipose fin, which is the small fleshy appendage located between the dorsal and tail fins. Finclipping is done at hatcheries, manually or mechanically, prior to the young salmon’s seaward migration. This mark is a common identifier in many fisheries.

Mark selective fisheries require some combination of enough marked salmon and zero or very low stocks of concern located in the fishing area. The objective is to rebuild salmon runs while providing modest angling opportunities. Fortunately, the US is required by law to mark nearly 100 percent of its hatchery chinook and coho. Unfortunately, Canada currently marks only about 15 percent of its production.

Consequently, MSF candidates are presently limited to areas with a high proportion of US fish. These include: The southern Strait of Georgia, the Juan de Fuca Strait from Victoria to Port Renfrew and Vancouver Island’s west coast.

If Canada started marking more salmon immediately it would take three years for those chinook and 1.5 years for coho to provide any benefits. Canada’s failure to mark enough salmon, combined with chinook-non-retention, has created a situation where most hatchery salmon cannot be retained.

Failing to mark most hatchery salmon may also be weakening the genetic integrity of some wild stocks. This is because wild and hatchery salmon have been spawning together for years without a visual means of identifying one from the other. It is a vexing concern.

The approved MSFs, located adjacent to Vancouver Island’s southeast coast, were only allowed because they posed minimal risk to chinook stocks of concern. They also have acceptable hatchery mark rates, which minimizes incidental mortalities (IMs) that would occur if too many wild salmon are released before keeping a marked chinook.

These proposals are seen as baby steps to re-starting chinook angling opportunities in future years, provided weak stock protection criteria are met. However, according to recreational fishery advisors, there are valid questions about why other, equally safe 2023 MSF proposals were declined.

MULTI-YEAR UBC INCIDENTAL MORTALITY STUDY NEARS COMPLETION

Incidental mortalities (IMs) are salmon deaths which occur as a consequence of injuries sustained from hooking and handling. These deaths may not be apparent but can happen minutes, hours or days after release. Until now most studies have focused on short term assessment of incidental mortality. The most comprehensive BC recreational study was done in the 1980s and 1990s by Terry Gjernes at Nanaimo’s Pacific Biological Station. He assessed immediate mortalities and injury categories. He then kept the surviving salmon in pens to record short-term post release mortality. However, mortality beyond these few days of confinement remained poorly understood.

What do IMs have to do with mark selective fisheries? If incidental mortalities are too high relative to the retained catch they create situations where releasing wild salmon is more costly than keeping wild salmon. It has also become a political football game pitting certain environmental nongovernment organizations against BC’s marine salmon anglers. These groups regularly claim that actual release mortality rates are far higher than the current rates being applied.

The IM picture will be clearer this winter when the results from studies that began in 2019 will be made public, according to UBC’s Stephen Johnston.

To date, the study has sampled and released 616 chinook that were caught using various combinations of recreational fishing gear and fish handling methods.

Johnston explains, “this builds on the work completed by Terry Gjernes, by expanding beyond the short term scope.” Johnston noted that keeping salmon in pens for observation, as Gjernes did, is a “two sided coin.” Extra mortalities do occur because the salmon are stressed in this unfamiliar pen environment, however, they are isolated from immediate post-release natural predation.

The research team tags each salmon. The tags allow them to be tracked by acoustic telemetry using stationary receivers along their expected migration routes. Their behavior can be monitored as they cross the arrays which provide information on each individual fish.

According to Johnston, “these tracking studies allow us to investigate survival patterns across longer time periods and spatial scales.” The studies will undergo rigorous peer-review prior to public release.

Us Federal Judge Closes Alaskan Troll Fisheries

US federal judge Richard Jones has thrown a wrench into plans for southeast Alaskan commercial summer and winter chinook troll fisheries. The basis of the judge’s decision is that Alaska’s fishing plans did not provide adequate protections for Southern Resident Killer Whales (SRKWs), in violation of marine mammal conservation laws.

The decision, which ordered the National Marine Fisheries service to redo an assessment that had previously permitted these fisheries, was welcomed by the Wild Fish Conservancy who brought the case forward, and by environmental groups in Canada. In a recent radio interview Raincoast Conservation Foundation’s Misty MacDuffee noted that Alaskan interceptions of Canadian salmon are “highly significant.”

It is estimated the decision could reduce impacts on chinook salmon in southeast Alaskan troll fisheries by 172,000 fish. Chinook salmon from northern and central BC, the west coast of Vancouver Island, interior Fraser River, Puget Sound, coastal Washington and Oregon and the Columbia River are impacted by Alaskan troll fisheries. Many of these stocks, particularly from the US, contribute to the year-long food needs of SRKWs who forage from mid-Vancouver Island to southern California.

Don’t pop the champagne cork yet. Alaska’s governor has already appealed the decision, consistent with Alaska’s history on the Salmon Commission as tough negotiators when the state’s fisheries are threatened.

This introduces another issue. Where does the Canada-US Pacific Salmon Commission fit into this story? The commission is guided by its own principles, such as ‘balancing salmon interceptions between the two countries.’ In its simplest interpretation ‘balancing interceptions’ means Canadian salmon caught by Alaska fishermen are balanced by Canadian interceptions of US salmon originating from the Pacific Northwest.

Initially this looks like a US domestic fight, pitting Washington, Oregon and Idaho against Alaska over protecting SRKWs, and reducing Alaska’s interception of their salmon. However, important Canadian fisheries are located smack in the middle. These fisheries are already severely constrained for conservation and whale protection reasons. Watch how this plays out, because the stakes are high if this dust-up expands beyond US borders.

TOM'S TIP

July’s Fishing Tip

Fishing line is a relatively cheap angling necessity, but anglers should avoid the temptation to buy low priced products that could become the weak links in the fishing system.

Today’s lines are very taskspecific, unlike lines from decades ago. For example: Use abrasion-resistant non-stretch lines for rockfish, cod and halibut because they telegraph bottom contact and fish strikes far quicker than lines that stretch. On the other hand, use lines that are abrasion-resistant with some stretch capacity for salmon, because a bit of stretch cushions head shakes, hard runs and other salmon hookthrowing acrobatics that can jar the hook loose.

One, Two, Three Forty-Six-Footers

dows (clears). The flybridge climate can be controlled with heat/AC vents that face both the helm chairs and forward toward the lounge. On temperate days rolling up the clears lets the breeze in which really feels wonderful. The extra space of the flybridge and the ability to open up all sides differentiates the 46 Sports Motoryacht from the other two 46s.

WINTERIOR Both the 46 Sports Motoryacht and 465 SUV have similar layouts below, but in the SUV the helm is in the main saloon to starboard so twin helm seats and controls replace a second inside lounge on the flybridge model. Below hen I found out that Riviera just came out with not one but three new 46-footers, I wondered why. After checking out these new boats I understand better and I think I can explain. Forty-six feet is a great size because a lot of utility and comfort can be offered, yet the boats are still easily managed by a couple. Convenient IPS joystick control further helps when shorthanded. Each new Riviera 46 has its own merits and enough differences to allow buyers to choose which model is the best for the way they boat. The Riviera 465 SUV and Riviera 46 Sports Motoryacht have the same hull and basic configuration. The Riviera 4600 Sport Yacht has a different hull, layout and styling. All three boats are around 50 feet overall (14 to 15 metres), are driven by Volvo Penta IPS pod drives, have three cabins and two heads and are packed with features and accommodations discerning yachtsmen expect.

ON DECK The 46 Sports Motoryacht has more living area and larger engines than the other two. This boat shares many features with the 465 SUV except for one major difference, a large open flybridge. Riviera is known for flybridge cruisers, and the 46 Sports Motoryacht respects that great history while taking it to another level with modern touches like an internal staircase and a lightweight, stylish hardtop complete with hatches for both ventilation and access. The flybridge is spacious at 4.67 x 2.82 metres delivering over 13 square-metres of living space. In addition to the two plush Pompanette adjustable helm seats there is a comfortable lounge ahead of the helm with a drop-down table, drink holders and stereo speakers. I like this set up because the helmsperson can eas- ily communicate with people hanging in the sky lounge and if children are on board they are in your sight. With the helm all the way aft I had concerns about visibility forward but when standing or with the seats boosted slightly, I could see over the bow with enough distance to spot logs and debris. The flybridge lounge is a great congregating area for drinks and appetizers, or lunch on the go, and a wetbar and fridge at the top of the stairs add convenience.

The back cushion on the port lounge is perfectly angled to watch the scenery while underway or curl up with a book and relax. The lounge table lowers, and a filler cushion creates a bed ideal for stargazing or cuddling at night. The entire flybridge is covered by the hard top and surrounded by flexible clear win-

Price starts at (Spring 2023) US$1,703,200 decks both these boats have the master cabin forward with an island berth and ensuite head. The other two cabins are under the main saloon with standing headroom at their entrances that lowers a bit at the beds. Hull windows keep the cabins light and with nearly a metre over the beds they are cosy not cramped. These staterooms can be configured with twin bunks, or one or both can be a double cabin which gives you excellent versatility and no bunk beds. Alternatively, the 4600 Sport Yacht features a full beam master cabin under the saloon with an ensuite head in addition to a VIP cabin forward featuring a double island berth and ensuite head access. A third twin bunk cabin is an option on the 4600 Sport Yacht, or that area can be set up as a lower deck lounge. Either way you get two substantial double cabins and stacked bunk beds or the open lounge which can be used for sleeping when needed. The 4600 Sport Yacht features a full-size washer and separate dryer and the 46 Sports Motoryacht and 465 SUV have a single combo unit.

All three models have fully appointed galleys aft of the saloon that feature wide solid surface counter tops with a carved spill gutter, stainless steel sinks, fridges, freezers, dishwashers and ample storage. Our test boat interior had rich mattefinished walnut cabinets and panels. Cherry and oak are options as is gloss finish. The position of the galleys provides easy access to both the saloon

COCKPIT Each model has a semi-enclosed aft seating area with a table ideal for entertaining, al fresco dining or simply lounging. This mezzanine lounge under the hardtop can be enclosed with clears and climate controlled although the 4600 Sport Yacht lends itself more to being open as the aft lounge isn’t fully covered. On the 4600 Sport Yacht one side hosts a vented electric barbecue, wetbar, fridge and icemaker. The 46 Sports Motoryacht and 465 SUV feature a mezzanine lounge that is easily enclosed and connected to an open cockpit a few steps below. At 5.67 square-metres the cockpit has room to fish with rod holders and an optional lighted, windowed, recirculating bait tank. An electric barebecue, wet bar, fridge and ice maker add convenience for outdoor entertainment. Twin transom doors connect the swim platform.

ON TEST I was only able to drive one of these three boats, the Riviera 46 Sports Motoryacht, but observed the 4600 Sport Yacht as she ran with us. The 4600 Sport Yacht was fast and nimble as we manoeuvred the boats side by side and looked stylish with her deep V bow cleanly slicing through the short chop.

Aboard the 46 Sports Motorayacht optional Volvo Penta D11 IPS 950s pushed us smoothly and rapidly as we jockeyed up alongside the other boat. All controls were in easy reach of the helm including the throttles and joystick, twin Garmin MFDs, C-Zone, engine monitors, Muir windlass remote, stereo controls and a compass. With only six degrees maximum bowrise, I could see over the bow fine even from the aft position helm. After cruising alongside the 4600 Sport Yacht for some photos I peeled off leaning the 46 Sport Motoryacht gently into some tight turns. An optional Seakeeper

6 was running during testing which may have helped the Riviera feel solid and comfortable even when turning at speed. Our peak speed was 35.3 knots and a comfortable fast cruise of 28 knots uses 225.2 litres per hour delivering a calculated range of 280 miles based on 90 percent of fuel capacity. That speed at 2,250 RPM seems to deliver our best performance as other speeds never quite attained that efficiency. The boat feels solid at 22 knots and 2,000 RPM and fuel burn moderates to using 189.3 litres per hour but the calculated range drops slightly to 262 miles. In fact, once on plane from 16.7 knots at 1,750 RPM up to wide open throttle at 2,550 RPM and an average of 34.4 knots the fuel burn in litres per hour steadily increases, but the faster speeds make up for it and the calculated range remains right around 260 miles. Basically, there is no speed penalty at the top end so if the conditions warrant it, you can run faster, get there slightly sooner, using roughly the same amount of fuel as you would if you slowed down a little. The 260-mile range should be adequate for cruising in the islands and you can pick your speed.

CONCLUDING REMARKS The performance and versatility of all three of Riviera’s 46-footers means the choice is up to you. If an open flybridge and that extra room on top matters, the 46 Sports Motoryacht delivers. If you want to drive inside, the 465 SUV or the 4600 Sport Yacht offer lower bridge clearance and less canvas and clears to deal with. Other major differences other than styling are the mezzanine configuration, whether you need an open cockpit for fishing/entertaining and your cabin layout preference. If you are in the market for a boat this size, Riviera offers three great new choices.
