Project Title
The effects of growth during early stages of development on the timing and investment in maturation
Description
Reproduction plays a pivotal role in the success and survival of a
species. The human demand on natural resources is increasing with
factors that are essential for the successful reproduction of
important salmon stocks need to be determined if they are to survive
in the modern world. Part of reproductive success is determined by the
quality, number and size of eggs produced. Previous work on wild and
artificially reared salmon has shown that growth during critical
periods of life can have profound effects on egg production. This
project manipulates the growth of coho salmon at various life stages
in order to determine the periods where good growth is essential for
subsequent optimal egg production. This will enable the development of
suitable protocols for artificially raising endangered salmon, and
allow us to predict the effects on reproduction of alterations in
normal growth patterns of salmon resulting from changes in the
environment.
