Objective(s): To establish the stored energy gains or losses of the various age/size classes and life history stages of Dolly Varden over the summer and over the course of the winter; to determine which age/size classes might be more susceptible to overwintering mortality and how such mortality depends upon stored energy reserves and critical life history activities such as spawning; to determine whether spawning adults go to sea to feed the summer before they spawn by comparison of spring and fall energy composition;
Project Description: The Researcher will continue to study the energy composition of and summer habitat utilization by Babbage River Dolly Varden. Fish will be collected by a number of methods, measured, tagged and released. A sub-sample will be dead sampled for sex, maturity and ageing structures as well as a number of dead samples will be frozen on site and transported to Winnipeg for analysis.
