The Cause and Effect of Overfishing

    Overfishing is a situation where one or more stocks of fish are reduced to below predefined levels of acceptance by fishing activities. Overfishing leads to environmental damage, failure of local economies, and poverty to those who live by fishing. Overfishing affects many people, from fisherman, and fish farmers, to the consumers of fish products. In this research paper, I will be explaining the cause and effect of overfishing, as well as how we can prevent overfishing and restore any area that

has been affected by overfishing.

    There are many causes for overfishing, but the main reasons include a growing population and economic benefits for commercial fishermen. As more fish are caught, the more money there will be for the commercial fishermen, so it’s not difficult to see why commercial fishermen contribute heavily to overfishing. Another cause of overfishing is a growing population. This is based off of the supply and demand theory. The larger the population is, the larger the demand is. In order to support the growing demand, you must increase the supply. In order to increase the supply, you must bring in more fish. There are two ways to do this. The first option is to increase wildlife fishing which could very easily lead to overfishing. The second option is to farm fish, which is less harmful to the environment, but they also have less worth in the economy. This concludes that fish farmers are less harmful to the environment, but also do not gain as much profit as commercial fishermen.


    Although fish farming seems like a great idea since it doesn’t lead to overfishing and as much environmental damage, there are still downsides to fish farming. Creating fish feeds for farmed fish depletes other fish species, which upsets the balance of a particular ecosystem. For example, it may take two to five pounds of wild smaller fish in order to farm one pound of salmon. Another problem with aquaculture, fish farming, is that the artificial food that gets fed to farmed fish may contain high levels of contaminants. These contaminants get eaten by the fish, and the fish get eaten by us, so basically, its not as healthy as wild fish. Fish farms may also harm the environment in another way. For example, the fish farmers would not want to lose farmed fish to sea birds, sea lions, and other predators that come their way, so they may kill

predators in order to keep their farmed fish safe.


    The effects of overfishing may include environmental damage, poverty to those who live by fishing, and increased fish farming. There would be increased fish farming, because if there is an area that is overfished, the local government may limit or ban commercial fishing.

    If this happens, there will be less supply. In order to meet the demans of the population, you must increase the supply, and since you cannot fish for supply, you must farm for it. The possible consequences of fish farming have been explained previously in this essay. There could be poverty to those who live by fishing because the local government may possibly ban or limit commercial fishing. Many of those who have lost their jobs due to this new ban, or limit may possibly have little or no other experience and may have difficulties finding another occupation to support themselves and/or their family. Environmental damage is also an effect of overfishing. For example, if all the sharks are overfished, since it is a main predator, smaller fish such as tuna could easily overpopulate. If there are so many tuna in the ocean, this may cause the number of small tropical fish to drop, which could easily wipe out coral reefs, because those little fish play a big role in coral reefs. Some may clean the coral by eating algae, some may help it grow by giving it the right nutrients, and some may keep predators away so they do not destroy the reef.


     This explains how to prevent or restore fish to their normal levels. Some ways to prevent overfishing would be to limit fishing, or even to ban fishing. The local government could also create sanctuaries/safe areas that forbid fishing in a certain area. This could be very helpful and still, commercial fisherman can do their jobs. In order to restore fish and their environment, you could limit or ban fishing until the normal levels of fish are restored.

    This proves that overfishing has a bad effect and that it should be prevented as much if possible. Commercial fisherman could do their job and not cause overfishing if there was an equal amount fish farming and commercial fishing.
