Communications: Iodophor Toxicity to Eggs and Fry of Fall Chinook Salmon

Abstract

Abstract Eggs of fall chinook salmon (Oncorhynchus tshawytscha) were treated for 30 min during the water-hardening stage with an iodophor containing 75 mg active iodine/L. The treatment significantly increased total mortality of eggs and fry. Water hardening of eggs in water for 30 min and then in the iodophor for 30 min also increased mortality.
