LENGTH-WEIGHT RELATIONSHIP OF YOUNG CARP (CYPRINUS-CARPIO) IN THE COURSE OF WINTERING

The length-weight relationship of young carp (Cyprinus carpio L.) was seen to change markedly in the course of the autumn, winter and spring seasons of investigation. A significant difference was proved between two young groups of different size and weight. In both young groups, the maximum weight decrease was noted in mid April, being 24.5% in sma ller young and 13.3% in larger specimens. A mutual comparison was made of the application of weight condition coefficients, b regression coe fficient of the exponential regression for length-weight relationship, absolute and relative weights and the methodological procedures. In a ll cases both non-adjusted empirical data of samples caught and adjust ed data of size-grouped young carp by length-weight relationship were used.
