Abstract :
Hatchery traits and growth of eggs and fry of rainbow
trout, Oncorhynchus mykiss, and arctic charr, Salvelinus alpinus, were
tested in fresh water of a low temperature. There were significant
differences (p<0.05) between the survival rates from fertilization
through the eyed stage and the first exogenous feeding. No significant
differences were observed between species with regard to feed conversion or
survival of fry at the end of the 154-day trial, but weight gain and
specific growth rate differed significantly (p<0.05). These results
suggest that the arctic charr could be considered an alternative to rainbow
trout, particularly in coldwater farms.
