Length-weight gain of European crayfish Astacus astacus (L.) in the area of the upper course of the Zeta river, Montenegro

Abstract

This paper presents the results of studying length-weight gain using exponential regression analysis. The gain was analyzed in the Slano, Krupac, and Liverovići Reservoirs and in the Zeta River. Comparing growth at different localities, we found different weight gains. The greatest weight gain exists in the population from the Slano Reservoir. Growth in the first year of life is much more intensive in this area than in populations from the literature we compared it to. .
