The core mission of the Physiology Program is to improve our
understanding of how fish adapt to environmental change and provide
fisheries managers with more predictive tools for resource management.
The main goals of the Team research are to improve our understanding
of: the physiology of fish growth, development, and reproduction;
the mechanism of olfactory imprinting and homing in salmon; and the
genetic and environmental control of life history patterns in salmon.
Team scientists have expertise in physiology, endocrinology, molecular
biology, neurobiology, fish nutrition, aquaculture and ecology.
Basic research is conducted on how the growth and reproductive
endocrine axes are regulated by environmental and nutritional factors,
and the cellular basis of olfactory mediated behaviors, especially
olfactory imprinting and homing. This fundamental information is
used to evaluate how environmental factors, nutrition, and hatchery
practices influence smoltification, survival in the early ocean
environment, reproduction (e.g. age of maturity, fecundity, egg size,
gamete quality), and straying in adult salmon. Results of this
research will aid in understanding the impacts of hatchery practices,
habitat quality, and global warming on the fitness of salmon, whether
they are wild or hatchery fish.
