Selected coelomic fluid parameters of sterlet, Acipenser ruthenus L.: effects of light color and photoperiod

Archives of Polish Fisheries, 2014
Light and color have effect physiological aspects of fish such as growth, the neuro-hormonal system, and reproduction. In the present study, the effects of light color and photoperiod on the levels of selected parameters of coelomic fluid (glucose, total

DataSheet_3_Draft Genome and Complete Hox-Cluster Characterization of the Sterlet (Acipenser ruthenus).xlsx

, 2019
Background: Sturgeons (Chondrostei: Acipenseridae) are a group of “living fossil” fishes at a basal position among Actinopteri. They have raised great public interest due to their special evolutionary position, species conservation challenges, as well as

Studying the efficiency of Gaprin application in sterlet farming

Siberian Herald of Agricultural Science
In the course of the experiment, the influence of new feed additives created on the basis of Gaprin and representing biomass of inactivated cell culture of non-pathogenic methane-oxidizing yeasts or bacteria on sturgeon fish productivity indicators was studied. The research was carried out in the Krasnodar Territory on sterlet fingerlings.
