The influence of genotype on habitat selection of fish and the analysis of population structure

Abstract

We used salmonids, eel and cod to demonstrate the apparent influence of genotype on the migratory behavior of fish and their selection of habitat. These examples indicate that the connection between specific genotypes and certain patterns of migratory behavior is typical of fish. This should always be taken into account in stock structure analysis.
