Description
Article written by Calvin R. Fremling regarding an experiment with specific toxicants and mayflies. Abstract: "A recycling test apparatus and burrow-containing artificial substrates were used to determine the toxicity of the lampricide 3-trifluoromethyl4-nitrophenol (TFM) against Hexagenia mayfly nymphs. Toxicity was relatively independent of temperature, but was greater in soft water than in hard water, and much greater at low than at high pH's; 12-h LC50's were 4.0 at pH 6.5 and 270.0 at pH 9.5." Published as part of a series: Investigations in Fish Control (issue 58) by the U.S. Fish and Wildlife Service (Department of the Interior). 8 pages. Part of the Cal R. Fremling Collection.
