He was told that fishes were not fit for human consumption because large amounts of pesticides had accumulated in the tissues of fishes. Why?, Because it is always advisable to use huge volumes of pesticide to rearing fishes, Because Pesticides don't get accumulated by the fish and are excreted out, There is no explanation for this event, Pesticides are transferred from lower trophic levels to higher trophic levels through the food chain. Over time, the concentration of pesticides in fishes reach a level which if consumed could cause serious metabolic and physiological disorders in humans.
