The Garrison Diversion Unit involves the proposed transfer of Missouri River water to a large part of eastern North Dakota for agricultural and industrial uses. Some of the water would flow into Canada through the Red River of the North. Canadian officials are concerned that some nonindigenous species might be introduced to their waters; namely, gizzard shad (Dorosoma cepedianum), rainbow smelt (Osmerus mordax), common carp (Cyprinus carpio), and Utah chub (Gila atraria). We investigated toxicants that might be used to augment other barriers that have been proposed. Chemicals tested against fish eggs and larvae were rotenone, potassium permanganate, chlorine, acrolein, cyanide, fluoride, ammonia, and nitrite. Eggs were generally more resistant than larvae. Only three of the toxicants demonstrated potential to control both eggs and larvae of the species of concern. Rotenone was the most toxic, followed by chlorine and potassium permanganate. Effective exposures required 6‐24 hours at concentrations ranging from 5 to more than 10 mg/ liter.
