摘    要:本文总结了1998~1999年三倍体太平洋牡蛎育苗与养成情况。98年在荣成三个863中试基地利用6-DMAP、冷休克及CB抑制表卵第二极体释放的方法诱导太平洋牡蛎三倍体,其中以6-DMAP效果较好,诱导三倍体率为60.9%~90.5%。共培育三倍体群牡蛎苗种4.13亿,海上养殖2000亩。三倍体群牡蛎的生长明显快于二倍体对照群体,体重增加15.65%~41.89%。1999年4~8月收获,三倍体群

关 键 词:太平洋牡砺  三倍体  育苗  养成

Abstract:The production of seed breeding and culturing of triploid Pacific oyster, Crassostrea gigas in 1998~1999 was summarized in this paper Triploid Pacific oysters were induced in three hatcheries in Rongcheng by inhibiting release of the second polar body with 6-dimethylaminopurine (6-DMAP), cold.,shock and cytochalasin B(CB) in 1998. Among the inducers used,6-DMAP was much more effective, with a triploid rate of 60.9%~90.5%. A total number of 41 .3 million triploid spats were yielded for 2000 mu of culturing area. Triploid Oysters grew faster than their diploid control group,with an increase of 15.56%~l .89% in body weight. Oysters were harvested during APril to August in 1999. The mean unit production of triploids is 20% higher than that of the diploids.
Keywords:Pacific oyster  triploid  seed breeding  culture
