中国对虾亲虾反季节培育技术的初步研究

The preliminary study on parental shrimp cultivation of Fenneropenaeus chinensis at the reverse seasons

20 0 1年 1 1月 1 8～ 2 8日自日照水产研究所等几处中国对虾越冬室筛选性腺有一定发育并已交尾的雌虾 36尾 ,并采用光线控制、水温控制、饵料调节、性腺催熟等方法 ,促使对虾性腺快速发育。至 2 0 0 2年 1月 1 0日从性腺培育成熟的对虾亲虾中选取 3尾 ,使用 0 5m3 塑料桶进行苗种培育。实验结果表明 ,中国对虾不经过常规的越冬管理 ,只要具备对虾亲虾发育的环境条件 ,在一定时间内性腺即可发育成熟 。

From Nov.18 to 28,2001, 36 mated Fenneropenaeus chinensis with 2～3 period gonad development were selected from hibernacle in Rizhao Fishery Research Institute and other places. Several methods, such as light and temperature treatment, bait regulation and gonad maturative technique et al., were employed in promoting their gonad maturity quickly. On Jan.10,2002, 3 shrimps with mature gonad were selected to breed in 0 5m 3 plastic′s barrel. Results showed that as long as the environment was compatible, the gonad of Fenneropenaeus chinensis could be matured and be used to breed without regular over-wintering management.
