摘要：

The European sea bass, Dicentrarchus labrax L., was successfully subjected to chromosome manipulation. Triploidy was induced by cold-shocking eggs at 0-2 degrees 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.
