Abstract: The toxicity of the lampricides 3-trifluoromethyl-4-nitrophenol (TFM), 2',5-dichloro-4'-nitrosalicylanilide (Bayer 73), and a 98:2 mixture of these compounds against fingerlings of seven species of fish -- brown trout, rainbow trout, lake trout, brook trout, channel catfis, bluegill, and yellow perch -- and to eggs and fry of coho salmon. Toxicities and sensitivities varied by species. The toxicity of TFM and Bayer 73 individually was influenced far more by pH than was the mixture in standard laboratory tests with rainbow trout. Toxicity of the mixture was additive or less than additive to all species and life stages tested. The mixture was slightly more toxic to larval lampreys than to other fish in comparable laboratory toxicity tests. |
