Abstract :

Studies of the pelagic fish early ontogenesis can be divided into two aspects: theoretical and practical one. Referring to the theoretical aspect, it is noted that the survival of fish in the early ontogenesis is determined by a complex set of biotic and abiotic parameters. There are four basic concepts of fry and young fishes population changes: the first – the "critical period", the second – ...

Abstract :

The influence of pH on of alpha-amylase, maltase, alkaline phosphatase and caseinlytic proteinases of the intestinal mucous membrane of yearlings of Russian sturgeon, Siberian sturgeon and their hybrid – ROLO grown in artificial conditions, was studied. In this case pH of the environment was changing from 3 to 12 (for the caseinlytic proteinases – from 6 to 12). The method of the nonmetric mu ...
