The effects of early thermal environment on growth, age at maturity, and sexual size dimorphism in Arctic charr (Salvelinus alpinus) are investigated. This study is a 654-day long rearing trial split into two sequential experimental phases termed EP1

Arctic charr Salvelinus alpinus of the Holar strain (mean ± s.e. body mass = 152·1 ± 3·1 g) were reared at four different salinity regimes at a constant temperature of 7·4° C. Two groups were given a three-month acclimation in salinity 18 befor

The protein requirements of Atlantic halibut (Hippoglossus hippoglossus L) were tested in two trials for fish with initial size of 564 g and 973 g. The fish were fed near isocaloric diets with crude protein in dry matter (CP) between 35% and 53%. The

In order to study the possible interactive effects of salinity and photoperiod on growth, feed conversion, and blood chemistry in juvenile halibut, 2,604 (initial mean weight 26.8 g ± 0.2 SEM) juvenile halibut were exposed to six different combinati

The effect of salinity on growth, feed conversion efficiency and blood physiology was investigated by rearing Atlantic halibut Hippoglossus hippoglossus (initial weight 25.5 ± 0.8 g, mean ± SEM) at salinities of 15, 25 or 32‰ for 4 months at 12
