The Consequences of Overfishing

Overfishing The massive fish obtained at the outset is called overfishing, but the problem with this definition arises from the lack of insight on the mechanisms regulating supplementation. First, consider the method of overfishing when resources are one-tenth of abundant biomass (Beverton et al., 1994). The second type examines the catch and population growth rate (Schaefers, 1954). The fishing rate will exceed the population growth rate and population growth rate will decline. This occurs when the fish is too young and this age allows an individual to achieve only a small fraction of its potential growth.

One of the most powerful examples of the economic impact of overfishing cited in this study is the capture of Atlantic salmon by Newfoundland. The stock collapsed and had a major impact on the fishermen - after eight years the value of the captured and captured fish plummeted from the peak of 980 million dollars in 1987 to 20 million dollars. According to the report, this area has not recovered and revenues since 1999 are not over $ 100 million. According to the survey, nearly one third of fishing grounds of large enterprises including Korean, Norwegian and Canadian companies are overfished. In addition, this analysis also revealed that most listed companies do not tell shareholders where their fish lies and the "risks to ecological and economic sustainability". "Of 19 companies with the largest direct fishery income, only 19 companies have disclosed this information on the annual report or on its website," McCarron said.

The problems facing the oceans of today's world are as great and deep as the ocean, from acidification, destruction of coral reefs to overfishing and fishery results. Fish has historically been the main food and still provides a stable supply of protein to many civilizations around the world. As a result of the rapid increase in the Earth's population, this led to a surge in demand, which led to overfishing (Fitzgerald, 2013). The problem that arises here is to predict overfishing by reducing demand, thereby minimizing the consumption of fish for consumer behavior and limiting it to sustainable procurement of fish or completely stopping it .

Indicators in 2017 indicate that coastal runoffs continue to deteriorate globally due to overfishing, agricultural water spills and eutrophication, ocean acidification, and massive destructive plastic contamination . Well, this plastic is ingested by marine ecosystem based organisms, as it suffocates large and attractive animals such as whales (whales and dolphins), sea turtles and seabirds. Ocean habitats and seeds play an important role in both ocean carbon cycle - bio carbon sinks that absorb carbon dioxide emissions and blue carbon stock - and more representative marine protected area network (MPA) It is now clear to establish clearly. Whether it is in the territorial waters of the country or on the high seas, it is an urgent matter. Only about 4% of the world's oceans are protected to a certain extent, there are convincing protection, ecological and economic arguments against the rapid and large scale expansion of marine protected areas.
