Collection and preservation of fish and other materials exposed to pesticides

The effects of pesticides on fish have become improtant to fish conservation since World War II, when DDT first came into common use. With the development of other potent insecticides and the increasing use of massive dosages in more recent years, the threat to fish and fish foods has increased. Fishery biologists have conducted some studies on the effects of insecticides, but it has been impossible for fishery science to keep pace with chemistry and agriculture.
