Abstract
Static 96-h LC50 values for 12 water-soluble herbicides with yearling coho salmon in freshwater were: acrolein 68 micrograms/l; dinoseb 100 micrograms/l; picloram 5.0-17.5 mg/1; 2,4,5-T (triethylamine)> 10 mg/l; atrazine> 15 mg/l; diquat 30 mg/l; amitrole-T 70 mg/l; paraquat 76 mg/l; dicamba> 100 mg/l; and Krenite and 2,4-D (dimethylamine)>200 mg/l. Amitrole-T, diquat, and paraquat exposure in fresthwater reduced the survival of salmon smolth placed in seawater. Diquat also inhibited downstream migration of smolts. Under normal field use, acrolein and dinoseb could produce mortality of all life stages of salmonids if treated irrigation waters were released into streams prior to herbicide inactivation. The use of diquat at recommended treatment levels could reduce downstream migration of smolts and decrease survival in seawater. All other herbicide formulations tested appeared to have no effect on smolting of coho salmon.
