Abstract

The results of a production experiment with juvenile muksun carried out at the Sob fish hatchery (Kharp village, Yamal-Nenets Autonomous Okrug) are presented. The purpose of the experiment, as an important element in the compensatory measure for the reproduction of valuable fish species, was to increase the biopotential of juveniles for their release into the Ob. For several days before hatching, the embryos were treated with ultra-weak pulsed magnetic fields in a specific frequency range. In the postembryonic period, control and experimental muksun juveniles were studied using morphometric and cytological-histological methods. It was established that the experimental juveniles during the entire growing period exceeded the control ones in most parameters, and before release into the Ob River for feeding, the weight of the experimental muksun fry significantly exceeded the weight of the control juveniles. When assessing the nature and degree of connection between morphometric parameters using cluster analysis, it was shown that by the time the experiment was completed, a higher correlation between traits was observed in the experimental juveniles, which is additional confirmation of its increased balance in the development process. The level of formation of the gonads of the reproductive system in the experimental individuals also exceeded the development of the gonads of the control ones - in terms of size and rate of sexual differentiation, number and cytometric indicators of germ cells. The data obtained allow us to consider it advisable to apply this approach in the practice of compensatory fish farming.
