Abstract The eastern part of the Black Sea and its tributaries are suitable habitats for several sturgeon species, among which Acipenser gueldenstaedtii , A. stellatus nudiventris persicus sturio H. huso well documented. However, different threats have led these species to a dramatic decline, all them currently listed as Critically Endangered some Locally Extinct in that area. We tested 94 wild...

The late sexual maturity in sturgeon and the absence of morphological differences between males and females makes sex discrimination difficult. Identification of sex at an early life stage is of high interest in caviar production because it allows efficient selection of females. In this study, the genome of 10 mature male and 10 mature female specimens of Persian sturgeon (Acipenser persicus...

Currently, the general trend of global fishing industry is to increase production fish food products not only due development aquaculture, but also biological characteristics body sturgeon. The aim study was theoretical justification and practical implementation assessment growth beluga juveniles their hybrids with sterlet aged 0+ 2+ (three-year-olds) in industrial Krasnodar Territory. determin...

in sturgeon aquaculture, where the main purpose is caviar production, a reliable method is needed to separate fish according to gender. currently, due to the lack of external sexual dimorphism, the fish are sexed by an invasive surgical examination of the gonads. development of a non-invasive procedure for sexing fish based on genetic markers is of special interest. in the present study we empl...
