| الوصف: | This study investigated whether coho salmon Oncorhynchus kisutch and Chinook salmon O. tshawytscha smolts would exhibit elevated compensatory growth rates in the spring after food deprivation during the winter. We also tested whether food-deprived fish would attain the same physiological attributes as smolts fed continuously during this period. Replicate treatment groups were deprived of food for 10 and 16 weeks, centered on the winter solstice. Control groups were fed to satiation 2 d weekly during the 10-week deprivation period and every day afterwards. All groups were fed daily to satiation from the end of the deprivation periods until after summer solstice. Treated fish of both species were smaller than controls after deprivation but grew faster after feeding resumed. Growth rates were not significantly different between treatment and control groups until the fish were transferred to seawater, which was 4°C warmer than freshwater at the time of transfer. At the end of the study in July, fish ... |
