ADVANTAGES: Fish farming provides a large and consistent supply of fish compared to natural fisheries by growing fish more quickly than natural fisheries. Furthermore, natural fisheries have restrictions on the quantity of fish that can be caught. Fish farming plays an important role in the effort to stamp out malnutrition by providing an adequate supply of protein rich in omega-3 oils and other essential nutrients required by the human body.
In addition to providing a source of income and employment, fish farming helps save certain fish species, such as cod, sea bass and red snapper, by reviving their populations with aquaculture.
DISADVANTAGES: One disadvantage of fish farming relates to environmental concerns. The large quantities of fish held by fish farms leads to overcrowding and results in the death of some fish, causing pollution in water sources. Once these become contaminated, the production of bacteria and rise of diseases may threaten the health of wild fish populations.
Another disadvantage of fish farming is that they require a significant amount of feed to grow the fish. Some fish require fish meal and others are fed corn products, both of which may be unprofitable.
