Growth Comparison of Induced and Mated Triploid Pacific Oysters
摘要
Abstract
Performance of induced and hybridized triploid Pacific oysters (Crassostrea gigas) was studied and compared for traits such as fertilization and hatching success, survival, larval and juvenile growth. The results showed that hybridized triploids were superior over induced triploids, and the difference in hatching success and D-larval size was significant (P<0. 05). Larval survival of the hybridized triploids was significantly higher than that of induced triploids. Juvenile shell height and shell length of hybridized triploids were larger than that of induced triploids, showing their superiority in growth. Flow cytometry analysis showed that the hybridized group contained 100% triploids, and the induced group had only (51.0+11. 8)% triploids. It is evident that hybridized triploids are superior over triploids induced by chemical treatment. Our study shows that mating diploids and tetraploids is an ideal approach to triploid production and is extremely valuable for large-scale production of triploid oysters.关键词
