Growth of Atlantic cod (Gadus morhua L.) with different haemoglobin subtypes when kept near their temperature preferenda

The effect of temperature on growth and feed utilization was studied over 56 days in Atlantic cod of different haemoglobin subtypes [designated Hb-I(1/1), Hb-I(1/2), and Hb-I(2/2)]. The fish, held in triplicate tanks, were reared at 6 and 14 °C (mean initial body weight, 218 and 212 g, respectively)...

Zusammenfassung:	The effect of temperature on growth and feed utilization was studied over 56 days in Atlantic cod of different haemoglobin subtypes [designated Hb-I(1/1), Hb-I(1/2), and Hb-I(2/2)]. The fish, held in triplicate tanks, were reared at 6 and 14 °C (mean initial body weight, 218 and 212 g, respectively). These temperatures are close to the preferred temperatures of Hb-I(2/2) (8.2 °C) and Hb-I(1/1) (15.4 °C). Temperature had a significant effect on SGR, with cod of all haemoglobin variants growing best at 14 °C (P
