Impacts of Ocean Fishing & Fisheries

The article “Environmental Impacts of Ocean Fishing & Fisheries” demonstrates that human activities have severely affected the marine life on the Earth’s oceans. Fisheries may be necessary for providing food and for the economy but they are causing huge damage to the environment. Environmentalists are warming us that if the fisheries continue to expand worldwide, negative impacts would dramatically increase and interfere with the trophic level within the ecosystem. Moreover, the author mentions that ocean fish stocks are constantly declining in the United States, and it is predicted by a relevant study that, at prevailing trends, the world would run out of wild seafood in 2048. Furthermore, our activities have been depleting the ocean water quality. The author shows that there are various ways by which human activities negatively impact oceans water and fish habitats. Overfishing is one of them: it occurs when the fishing sector catch more fish than what can naturally regenerate through reproduction. Also, pollution and contamination contributed to the degradation of oceans water. We are dumping our wastes into the oceans (industrial run-off, toxic waste, radioactive waste, waste from agriculture activities). Marine traffic generates tons of hydrocarbon a year (burning fuel). In the article, it states that the two major causes of loss of ocean salmon are the high harvest rates and the building dams on rivers. Furthermore, one way we are contributing to the loss of ocean fish species and the marine life is by using damaging methods that affect natural habitats and ecological balance of the oceans. Some of those methods are explosive fishing, cyanide fishing, and bottom trawling. The article proposes some ways to improve wild fishing, such as promoting good fisheries management, combating illegal fishing, cutting down destructive fishing practices, and developing and practicing new technologies.

In my opinion, I understand that wild caught fish are an important protein source but I believe that the current fisheries rules are no efficient and the fishing capacity is not enough controlled/enforced and limited. Moreover, I think that fisheries should not take more species than populations can sustain, and I also believe that the methods of how we fish really matters. It requires a very good management to solve the problem of overfishing and the government should do something about it.


I chose your article to comment on because I agree with you when it comes to trying to create stricter rules on fishing wild species of fish because they are in danger and this is known by many people. Sadly, some humans do not care at all about all the waste they create and their impacts on the ocean. It is even more shocking to know that we would run out of seafood by the year 2048 if we continue at this paste. It is horrifying to know that in our lifetime, this will happen. We always assume that these problems are so far away and that we have time to fix them, but it is not always the case including this one. In New Zealand, there have already been a very large decrease in fish including trout and salmon which is making people panic. Their water supplies are also lowering making it even harder for people to drink water without questioning themselves it is toxic or not.

I chose to comment on your summary because much like yourself, I also believe that fishing is an important source of sustenance in an increasingly vegetarian society, and that we must draft and apply stricter regulations to fisheries. As your article proposes, by 2048 it is quite possible that little to no sustainable sea life remains for industrial fishing, also supported by the Asian Pacific Post and the United Nations. In fact, overfishing has become so rampant in certain parts of the world that scientists hypothesise that by 2048, the Asian oceans will have lost over 45 % of their biodiversity and over 90 % of their corals (Mata Press Service). The assertions you made and supported concerning the various causes of ocean pollution, loss of biodiversity and reduction in water quality are all of vital importance to the planets ecosystems. These are all, however, very complex issues, with equally complex solutions. Yet, there does exist a viable alternative which would, in my opinion, provide a “complete” solution, requiring fewer steps than attempting to resolve each variable on its own; aquaculture. Aquaculture, is quite simple the farming of marine life in controlled and often artificial environments. Thus, rather than polluting the natural environment, fishing companies create large water reservoirs and grow their fish, process and restart. This allows for a minimum of pollution, it ensures that the natural environments are not overfished to the point of replenishment becomes impossible and should reduce the costs run by companies (Mata Press Service). Humans have grown accustomed to overconsume, and as this remains a world run on money, it would be quite difficult to convince corporations to reduce their production and profits in exchange for stronger regulations and taxation on pollution. Therefor, at least for now in my opinion. A most viable option would be to substitute our ocean fisheries by aquaculture fisheries in the hopes of saving what remains of our ocean biomes.
