Current Research
Penny Swanson's current research projects involve both basic and applied studies on the endocrine control of reproduction in fish, primarily salmon. Her main interests are the physiology of gonadotropins, mechanisms of puberty in fish, and how growth and environmental factors influence the age of sexual maturity. Under the Captive Broodstock Research Project funded by the Bonneville Power Administration and in collaboration with Brian Beckman, Briony Campbell and Karl Shearer, she is conducting research on how growth at various points of the life cycle influences the age of sexual maturation, fecundity, egg size and gamete viability. The goal of this research is to develop diets and growth regimes that allow for better control of the age of maturation in captively-reared fish. She is also investigating how rearing temperature influences the seasonal timing of spawning and trying to develop methods to advance spawning time in captively reared fish, which are delayed from wild fish. In collaboration with Jon Dickey and other scientists in Europe she is conducting molecular studies to better understand regulation of hormone receptors, such as gonadotropin-releasing hormone and gonadotropin receptors.
