5203 |a"Coho smolts leaving Black Creek, French Creek, and the Trent River between April 13 and June 20, 1990 were trapped and coded wire tagged. We tagged 118,410 coho smolts at Black Creek, 40,763 at French Creek, and 10,439 at the Trent River. The estimated total number of smolts produced in each system was 119,602, 41,835, and 11,126, respectively. Mortality due to trapping and tagging was low (0.1-1.6%). Wild coho smolts were primarily age 1; only 8.2% were estimated to be age 2 at Black Creek, 4.1 % were estimated to be age 2 or 3 at French Creek, and less than 1 % were estimated to be age 2 or 3 at Trent River. Black Creek smolts were significantly larger than Trent River smolts, and Trent River smolts were significantly larger than French Creek smolts. Outplant smolts comprised 5.9% and 48.2% of the migrating coho in French Creek and the Trent River, respectively. At the Trent River, estimated overwinter survivals for fry outplanted at four locations in the watershed differed significantly from those of the previous year. In all three systems, stratified mean lengths and weights were typically greatest in the early part of the smolt run. Male smolts always made up a greater proportion of the populations, and on average, comprised approximately 60% of the smolts in each of the three systems"--Abstract, page viii.
