Abstract
Turbot, Scophthalmus maximus, were kept in tanks and weighed every month for about two
years. Haemoglobins of 90 untagged and 52 individually Pit tagged fish were analysed by agar gel
electrophoresis. A polymorphic system was found in the haemoglobins. The electrophoretic patterns
indicated a dimer structure of the proteins. Based on the observations the fish were classified into
three phenotypes, supposed to represent three genotypes named; Hb-I(1/1), Hb-I(1/2) and Hb-I(2/2).
The phenotype specific growth rate of the fish were analysed using weight data of the individually
tagged fish. In addition the final weights and lengths of the untagged fish were analysed for
differences in mean size of the phenotype groups
