Data analysis of 1986 and 1987 Hecate Strait juvenile salmon surveys / by B.J. Waddell, M.C. Healey and J.F.T. Morris.: Fs97-6/1719E-PDF

"This report analyzes juvenile salmon data collected during surveys in Hecate Strait in the summers of 1986 and 1987 (Morris and Healey 1987, 1988). The primary purpose of these surveys was to gather information on the abundance, species composition, size composition, and diet of juvenile salmon in Hecate Strait, for validation of a migration model designed by Healey (1986). The model predicts juvenile salmon abundance, size, and food resource requirements in Hecate Strait, based on assumptions about smolt production, growth rates, mortality rates, run timing, migration speed, and the migration route, for each species from six B.C. coastal regions. If the model is validated, it will assist in evaluating how Hecate Strait is used as a migration corridor and rearing area by juvenile salmon. Juvenile salmon sex ratios, size composition, length-weight relationships, and interspecific correlations of size and catch rate among purse seine sets are all discussed in this report"--Introduction, page [1].
