Spermal activity and change in Pacific salmon features

The fishes progeny is the prospective to obtain in culture on the base of selected best gametes and best combinations of heredity factors, however this problem is complex. Also we considered important to find connection of gamete features with biological ones of progeny. The activity of sperms as feature, which can be influenced by selection, was studied. The methods of gamete selection (GS) which decreased rate of heredity defects were viewed. We explored progeny of chum salmon Oncorhynchus keta, pink salmon O. gorbuscha, chinook salmon O. tshawytscha and sockeye salmon O. nerka after gamete selection. Following features of progeny were described: survival; sexes ratio; fluctuating asymmetry (FA); diversity of features. FA is used as quality index of ontogenesis stability in development. We found that near 40-50% of chum salmon FA is controlled by heredity apparatus. The chum salmon (Sakhalin Island, Sokolovsky hatchery) and chinook salmon (Kamchatka, Malkinsky hatchery) researched in the presented work is characterized by high occurrence of fluctuating asymmetry.
