Evaluation of morphological indicators of the first mature sturgeon females from eggs in artificial conditions
Abstract Sturgeon species of fish are a unique branch of the relict fish fauna. Species biodiversity, features of biology, a wide range, nutritional value, all taken together, made it possible to distinguish this group of fish in an independent direction-sturgeon breeding. In the last century, Russi...

Abstract Sturgeon species of fish are a unique branch of the relict fish fauna. Species biodiversity, features of biology, a wide range, nutritional value, all taken together, made it possible to distinguish this group of fish in an independent direction-sturgeon breeding. In the last century, Russia accounted for up to 90% of the world’s stocks of these fish species. According to the number and species composition of sturgeon, the Caspian basin occupied a dominant position.
