The low level of genetic variability of the donaldson rainbow trout strain






Eesti NSV Teaduste Akadeemia Toimetised Bioloogia 35(3): 193-197

The low level of genetic variability of the donaldson rainbow trout strain

The L. R. Donaldson strain of rainbow trout introduced in Estonia is characterized by a very low level of genetic variability of proteins. There are significant differences between the Donaldson trout and the usual populations of hatchery-reared Estonian trout in respect to the genetic composition of their gene pool and the average heterozygosity. The loss of genetic variability in the Donaldson strain is caused by intensive selection and reduced population size.
