Philoid · Accepted Answer

The fishes were not fit for human consumption because large amount of pesticides had accumulated in the tissues of fishes as a result of biomagnification.Biomagnification is the process in which the pesticides get slowly accumulated in the fishes or other marine animals thereby results in the decline of other species which feed on them.
