Research:

Dr. Trippel is the Aquaculture Biotechnology Research Scientist with DFO at the St. Andrews Biological Station. His research interests include Atlantic cod and haddock physiology in support of reproductive biology, selective breeding, gamete cryopreservation, genetic improvement programs, marker assisted selection, triploidy, and photoperiod manipulation to enhance growth and suppress sexual maturation for aquaculture. He collaborates extensively with the aquaculture industry, universities and other government institutions in support of sustainable coldwater mariculture of marine finfish species.
