Description of Research Interests:

 

 My research interests focus on the interactions of reproduction and growth and how they can be manipulated to benefit aquaculture.  Control of reproduction is important for seed stock production, selective breeding, growth rate, feed efficiency, meat quality, and biosecurity. These needs to control reproduction differ among segments of the rainbow trout industry. Earlier maturation may be desirable for seed stock production and selective breeding efforts, whereas delayed maturation, sterility, or monosex production may be desired for improved growth rate, feed efficiency, meat quality, and biosecurity.  Often diverse aquaculture needs can often be addressed by greater control over a shared underlying reproductive process, in these particular examples, the onset of puberty.  No matter the impetus for aquaculturists to want to alter reproductive events, progress in gaining control over reproductive processes is dependent on our gaining a greater understanding of mechanisms controlling these processes and how they are affected by aquaculture practices including selective breeding for diverse traits.  Current research in my lab ranges from characterizing functions of intraovarian growth factors to effects of selection for improved growth and stress response on reproductive performance.
