Research Interests

Our laboratory is involved in basic and applied genetic research in fishes, especially trout and salmon. We utilize a variety of chromosome set manipulation procedures to trout and salmon to increase our understanding of basic genetics in these fishes and for their genetic improvement. Androgenesis and gynogenesis involve producing offspring with both chromosome sets from one parent and can be useful for producing inbred lines, gene mapping and other studies. Triploids can also be readily produced and are of interest because they are sterile and because triploid interspecific hybrids have been demonstrated frequently to be much more viable than diploid hybrids. Our laboratory is also analyzing DNA polymorphisms in trout and salmon with the goals of developing improved genetic maps, identifying markers for conservation programs and identifying single genes with significant physiological effects.
