原始语种摘要: Abstract(#br)In a preliminary study, 121 individually tagged juvenile Atlantic cod ( Gadus morhua ) were classified according to their haemoglobin genotypes into four groups, i.e., two main haemoglobin genotypes [ Hb-I(1/2), Hb-I(2/2) ] and two sub-types [ Hb-I(1/2b), Hb-I(2/2b) ], and reared for 3 months at 10 °C, 13 °C and T-step (fish reared at 16 °C and then subsequently moved to 13 and later to 10 °C). Overall growth rates across temperatures were 10% and 19% higher in the Hb-I(2/2b) , Hb-I(1/2b) sub-types compared to corresponding Hb-I(2/2) and Hb-I(1/2) main types, respectively. Individual growth rate trajectories varied between the genotypes at all temperatures studied. Our study indicates that under certain environmental conditions higher growth in the two sub-types compared to...
