К морфо-экологической характеристике ерша полосатого — Acerina schraetser (L.)

Abstract

In the course of the studies it was determined that in Acerina schraetser (L.) sex dimorphism is not manifested and size-age variability is expressed by 11 plastic characters. A. schraetser grows most intensely for the first two years of life. There are no essential differences in fatness of males and females and individuals of different size. Insect larvae and crustaceans are predominant in .4. schraetser food.
