Abstract -- Introduction -- Chronic-toxicity tests on bluntnose minnows -- Chronic-toxicity tests on guppies -- Acute-toxicity tests on bluntnose minnows -- Effect of endrin on oxygen consumption -- Effect of endrin on swimming of bluntnose minnows --Port of entry into the distribution of endrin in the fish's body -- Mode of action of endrin on animals -- Summary -- Conclusions -- Literature cited -- Appendix raw data from tests In an investigation of chronic toxicity of endrin to bluntnose minnows and guppies, conducted for 291 days, neither species could withstand concentrations greater than 0.5 parts per billion of endrin in water for more than a few days. Less than 50 percent of the test animals could live in 0.5 p.p.b. for more than 30 days. Approximately 65 percent could live in 0.4 p.p.b. for periods exceeding 30 days, while there was little mortality due to endrin on 0.25 and 0.1 p.p.b. endrin in water.
