Aquaculture or fish farming can be used to increase the availability of species like salmon and shrimp for consumption. Although
fish farming can have a number of negative environmental effects, it does offer a number of advantages. Which of the following is a valid reason for promoting the use of fish farms? A. Fish production is constant, and fish farming reduces pressure on wild stocks.
B. Fish raised at fish farms are cheaper and have a better flavor than wild-caught fish.
C. Fish farming generates few, if any, pollutants that affect adjacent waterways.
D. Pesticides and antibiotics are rarely used at fish farms but are often used in wild-caught fish populations.
A. Fish production is constant, and fish farming reduces pressure on wild stocks.
Irrespective of the negative effects fish farming has on the marine environment, one of the major advantages that fish farming has is that it helps in reducing the pressure on wild stocks.
With annual consumption of fish that is being reported to have increased in recent times tremendously, meeting this growing demand has put a lot of pressure on the already depleted wild stocks. Therefore, in order to meet this growing demand of fish, aquaculture or fish farming can help to fill the gap as the pressure on wild stocks is reduced.
