Physiological and biochemical parameters of round goby breeders from the Azov Sea have been studied during their spawning and the results are presented. The reproductive abilities are shown to be decreased in the females sampled in some investigated areas. We have come to a conclusion that slow transportation of trophic substances from the liver to the gonads can decrease the reproductive potential of breeders, and finally can be a cause of low fish fecundity and poor viability of the progeny.
