Abstract: The serum protein composition and its content of steelhead(Salmo gairdneri),golden trout(Salmo gairdneri),rainbow trout(Salmo gairdneri),Arctic char(Salvelinus alpinus Linnaeus),and brook trout(Salvelinus fontinalus Mitchill)were analyzed by native polyacrylamide gel electrophoresis.The results show least genetic distance among the steelhead,golden trout,and rainbow trout,and the largest genetic distance trouts(steelhead,golden trout,rainbow trout)and brook trout,and were in the same subgroup with Arctic char,indicating that trouts and brook trout have closer phylogenetic relationships in comparison with Arctic char.Electrophoretogram analysis on serum protein in several salmons was proved as a simple,reproducible method,for providing experimental data for species identification,breeding selection,varieties improvement,and genetic structure analysis of salmons.Rainbow trout propagation and culture need to be further standardized in order to reduce the loss of protein genes,and prevent large-scale disease outbreaks of trouts.
