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.
