Cobia (Rachycentron canadum) exhibit differential growth rates between the, sexes, with females growing faster than males. Sex determination mechanisms, have not been elucidated for this species, nor are there any literature reports, regarding the induction of sterility through triploidy or attempts at generating, uniparental inheritance., The research outlined in this proposal will establish protocols for the induction of, gynogenesis and triploidy in cobia. Specifically we will determine the appropriate, methods for suppression of second meiosis in newly fertilized eggs and the, protocols needed for inactivating parental sperm DNA., SUMMARY OF
Anticipated Results:, Success in this project will enable the development of sterile triploid and, monosex female stocks of cobia for use in production operations. Both, technologies will lead to improved and more efficient production of cobia
