of a bad management within the business.
What is Fishery depletion? By: Daniela Vásquez Fishery Depletion, also known as overfishing, is one of the world issues that we have nowadays. It is when too many fish are caught. Because they are caught all throughout the year they don’t have the opportunity to reproduce and maintain the specie. When time passes by, that can also cause the extinction of the specie. This happens basically because they are wedged and then sold in the market. The fishing industry has a very good income. For example, in 1990, the approximate money that it made was about $70 to 80 billion for only 125 million tons of fish. Today, fisheries earn around $50 billion each year. The fishery industry is a very unstable business because of the excess of fishing and they practically stop the nature’s cycle. In 1992, there was an immense collapse in the cod fishing in Canada and there was a collateral effect, meaning that there were 40,000 lost jobs. The North Sea and the Baltic are really close to having a complete collapse, which means that they can’t produce fish anymore. This wasn’t the only cause of the fishing company to decline, but there was also a lot of illegal fishing within the sea. Now the percent of the illegal fishing is 30 %. The illegal fishing is the product
In the other hand, the ocean is one that turns out to be the most injured in this whole situation. The jobs can be recovered and because there are more job opportunities out there (worldwide), but there is only one ocean but there is only one ocean that cannot be replaced .This catastrophe is called the Tragedy of the oceans. A few years from now, 90% of the fish that we can eat \ won’t exist anymore. Some of them are the tuna, blue marlin and halibut. How does it happen? Fishery depletion is when, for commercial or non-commercial practices, catch too many adult fish are caught. This makes them have the option to fish the fish that aren’t completely mature. This leaves the specie with no way unable to reproduce and increase their population.

effects of the extinction of this specie could be: a negative impact on other marine species because the tuna is on top of the marine food chain. Also that they will have slower reproductive rates, which means that population will take longer to recover. Likewise, the prices have gone up because of the fewer number of fishes. For example, a single, healthy sized adult could bring about $100,000 dollars to Tokyo largest fish market. Those are reasons why we should start making conscience now and start protecting this species of fish because if we keep waiting, then it would be too late.

point we are going to lose types of fishes we like.
By: Cristina Donoso Do you know what over fishing causes? Over fishing is a big problem that started on 1950s when large scales of fishing industries started. With this industries and the technology they got fish do not stand a chance since with big machines they fish them all, over their technology and as a result there are big amounts of fish being fished.
The problem of the lost of some species of fish we like has already happened. In 1992 in Newfoundland, Canada an industry over fished the cod in this area. This didn’t just affect the ecosystem it affected the people from the industry as well. The decreasing of fish led to the loss of 40,000 jobs in the industry. People have to be aware of what over fishing can cause people as well to not a good ending. But some fishing industries instead of hearing the scientist advice on what they could do industries are heading towards the pacific, looking for new fishes to fish. Fisher depletion affects us all.
Big fish ones like: tuna, sword fish also called marlin; cod, halibut skate and flounder are more frequently fished. These fish have been over fished since 1950 .and as a result 90% of these fish have been overfished which causes the entire ocean ecosystem to shift. The over fishing of these fish has affected the local people how depend as well on fishing because they got as well no more fish to fish. And people how fish have to replace this big fish with smaller ones. In the end over fishing at the end affects us, at some
