Temporal genetic variation of brown trout Salmo trutta L. from Vorobiev creek (White sea) based on allozyme analysis

Abstract

We performed an analysis of allozyme variation in brown trout from Vorobiev creek. Seventeen allozyme loci encoding glycerol-3-phosphate dehydrogenase (G3PDH), aspartate aminotransferase (AAT), malate dehydrogenase (MDH), lactate dehydrogenase (LDH), superoxide dismutase (SOD), and esterase D (EST-D) were studied. We found statistically significant differences in allele frequencies for the AAT-1,2*, G3PDH-2,3*, LDH-5*, and MDH-2* loci between brown trout samples collected in 1981–1982 and/or 1992–1995. We suggest that temporal changes of allele frequencies in brown trout from Vorobiev Creek are associated with gene drift.
