Monitoring work on artificial reproduction in the Astrakhan region

 

In June-July of this year, a grading survey of juvenile sturgeon fish species was carried out, during which an assessment of the fish-breeding, biological and quantitative indicators of juveniles was carried out, and samples of juveniles and zooplankton were taken to determine the intensity of feeding during pond cultivation. Based on the results, an assessment will be made regarding the use of biotechnical indicators for breeding sturgeon fish species, the quality of released juveniles and an examination for the presence of diseases.

 

As part of the commission of the Volga-Caspian territorial administration of the Federal Agency for Fisheries for monitoring activities to implement work on artificial reproduction, specialists of the branch assessed the results of growing young semi-anadromous fish species - bream and carp in areas of Astrakhan spawning and rearing farms.
