Effect of reduced incubation temperatures on survival of trout embryos



Effect of reduced incubation temperatures on survival of trout embryos



Progressive Fish-Culturist 56(3): 180-184



The effect on embryo survival of reducing egg incubation temperature from 7 degree C to 4 or 2 degree C immediately after 2 h of water hardening was tested for three hatchery species of trout. Embryos incubated at 2 degree C had significantly lower survival rates to eyeing than embryos incubated at 4 and 7 degree C. Embryos of fall-spawning brown trout (Salmo trutta) and spring-spawning rainbow trout (Oncorhynchus mykiss) had higher survival rates than cutthroat trout (O. clarki) and domesticated fall-spawning rainbow trout when incubated at 2 degree C. The rate at which temperatures were reduced from 7 to 4 degree C or from 7 to 2 degree C had no effect on embryo survival.
