Searching the genome of beluga (Huso huso) for sex markers based on targeted bulked segregant analysis (BSA)
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 proced...
