United States Department of the Interior, Fred A. Seaton, Secretary Fish and Wildlife Service, Arnie J. Suomela, Commissioner LETHAL DOSES OF SEVERAL COMMERCIAL CHEMICALS FOR FINGERLING CHANNEL CATFISH by Howard P. Clemens University of Oklahoma cind Kermit E. Sneed University of Oklahoma Research Institute Norman, Oklahoma United States Fish and Wildlife Service Special Scientific Report — Fisheries No. 316 Washington, D. C. September 1959 11 LETHAL DOSES OF SEVERAL COMMERCIAL CHEMICALS FOR FINGERLING CHANNEL CATFISH by Howard P. Clemens and Kermit E. Sneed The data in the following table were collected during the screening of several chemicals to determine the toxicity of some of those in use or that might be useful in various phases of channel cat- fish culture. The information reported should be useful to fishery workers interested in control of diseases, pEirasites, aquatic vegeta- tion, and pollution of our streams and lakes. We have not yet tested the effectiveness of these chemicals for these control purposes. Experiments were conducted in a manner identical with those previously reported —' , with the exception of chemicals marked with an asterisk in table 1. In these tests, 4-gallon aquariums were used instead of quart jars, and 10 channel catfish fingerlings, 2 to 3 inches long, were placed in each aquarium. The diluent in all cases was tap water of the University of Oklahoma, and its chemical analy- sis was reported in the paper referred to above. One hundred or two hundred fish were used in each experiment, 10 fish at each concentra- tion. All concentrations are reported as parts per million (p. p.m.) by weight of material as it came from the bottle except that chlor- dane, acetic acid, Chem-Fish Special, sodium arsenite, toxaphene, sodium pentachloTophenolate, and formalin were expressed as p. p.m. by volume. We are grateful to the following companies who supplied the various chemicals in addition to others which have not yet been tested: American Cyanamid Company; Barada & Page, Inc.; California Spray Chemical Corporation; Carbide and Carbon Chemicals Company; Chemical Insecticide Corporation; Dow Chemical Company; E. I. du Pont de Nemours & Company; Mallinckrodt Chemical Works; Merck & Com- pany, Inc.; Monsanto Chemical Company; and Thompson-Hayward Chemical CompEiny. \/ Clemens, Howard P., and Kermit E. Sneed.
