| Abstract: | Oxygen consumption rates of post-smolt Atlantic salmon (Salmo salar L.) were recorded during various growth trials at four land-based salmon farms in south-west Norway, during the period 1988–1992. Principle component analysis indicated that fish size, water temperature and current speed had the greatest influence on oxygen consumption of fish in all the farms. A multiple regression analysis showed that 70% of the variation in the oxygen consumption could be explained by these three parameters. The predicted effect of fish size, water temperature and current speed on oxygen consumption are consistent with those reported in studies conducted on salmonids held in tunnel respirometers. The model described in this study may be a useful tool for the estimation of oxygen and water requirements needed for the design and operation of land-based farms. |
