Abstract
The European sea bass, Dicentrarchus labrax L., was successfully subjected to chromosome manipulation. Triploidy was induced by cold-shocking eggs at 0–2°C for 20 min starting 5 min after fertilization in order to prevent the extrusion of the second polar body. Meiogynogenesis was also obtained by fertilizing eggs with UV-irradiated sperm (3300 and 6600 erg m−2) and subsequently doubling the chromosome set by meiotic block as above. The commercial advantages of culturing triploid and gynogenetic sea bass are discussed.Keywords
