Fish Conservation Genetics

Our group uses population and conservation genetic tools to study the evolutionary impacts of anthropogenic changes and fishery activities on fish populations. Our main questions include:

• How important are genetic variations within/between populations for adaptation and conservation?
• What are the effects of fishery activities on the genetic variation in wild populations?
• What is the mechanism responsible for genetic differentiations of fish due to environmental and anthropogenic changes, such as artificial propagation?

Ongoing projects

• “Rapid Evolution in Captivity”: a systematic evaluation of the mechanism of fitness loss in captive-bred brown trout in the wild. (SNSF project)
• “River fragmentation and defragmentation” (CCES - ENHANCE project in collaboration with Armin Peter and Laura Langeloh)
• Theoretical evaluation of the effects of hatchery fish stocking in wild populations
• Power analysis of fitness difference tests under realistic conditions
• Comparative genomics and population genetics studies on DNA sequences (in collaboration with Nanjing University)
• Population genetic studies on flatfish asymmetry gene (in collaboration with Japanese and US researchers)
