Popis:	A study of polymorphic allozyme loci in five samples of rainbow trout Oncorhynchus mykiss from central North Island, New Zealand, showed no significant differences in allele frequencies among samples. These and results from similar studies suggest that no genetic differentiation at allozyme loci has occurred in New Zealand rainbow trout since the species was first introduced from coastal California in 1883. This contrasts with recent studies showing differences in morphometric and developmental characters among New Zealand rainbow trout populations, some of which seem to be heritable.
