Sex Control in Shrimp and Prawn Aquaculture
Description A novel approach to isolate the Androgenic sex hormone (AH) from the crustacean freshwater prawn and marine shrimp using in vitro glandular secretion of the AH from AH-producing Androgenic glands. Yields in commercially important, female-superior, sexually dimorphic shrimp can be dramatically improved by using all-female population (reaching 20%-30% larger body size than males) generated by mating normal genetic females with genetic females that have been "sex-reversed" into "neomales." The latter have been produced by the inventors by implanting the AH producing Androgenic glands, responsible for male development, into immature genetic females. The same has also been accomplished by immersing the immature genetic females into an AH solution.
