Abstract
Ceratomyxa shasta is a parasite of salmonid fishes that causes significant mortalities of fish populations in the Pacific Northwest. Genetic resistance to C. shasta has already been documented at multiple loci in rainbow trout (Oncorhynchus mykiss) and offers opportunities to combat the disease. We investigated resistance of multiple lines of clonal rainbow trout over two years against a number of C. shasta genotypes in an attempt to identify potential fish lines for future study. Additionally, a recombinant cross between the OSU and Skamania clonal lines was exposed to the form of the parasite most virulent to rainbow trout in order to see if a fish line with a robust resistance could be developed. Despite the fact that sample sizes were small, results suggest that different rainbow trout lines show variation in resistance to C. shasta and that development of a robust resistance is possible.
