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 – ...
