江西省中华鳖种质状况及养殖方式调查

Investigation on germplasm and culture method of Pelodiscus sinensis in jiangxi province

对江西省中华鳖的主要养殖企业分布、种质情况及养殖模式等进行了调查,结果表明:全省各地均有养殖,有一定规模的养殖企业主要分布于南丰县、黎川县、玉山县、永修县、余干县、进贤县和弋阳县等地;主要的养殖品系有鄱阳湖中华鳖、广东绿卡中华鳖、日本品系中华鳖、黄河中华鳖等;采用的养殖模式主要分为3种:常温养殖模式,控温高产养殖模式和生态化高产养殖模式。测量了不同养殖企业的6个中华鳖养殖类群的13项形态指标,从形态数据方面分析了不同养殖类群的种质。英明养殖类群系黄河中华鳖、日本品系中华鳖和台湾鳖的杂交种;富源养殖类群为鄱阳湖中华鳖,但推测其有广东绿卡中华鳖品系的混杂;进贤养殖类群是鄱阳湖中华鳖、广东绿卡中华鳖、日本品系中华鳖和黄河中华鳖等品系的混杂种;京丰养殖类群、兴初养殖类群和永修养殖类群是鄱阳湖中华鳖,但不排除有其他品系混杂的可能,其种质有待进一步研究。

The distribution of main culture enterprises in Jiangxi Province were investigated in this paper. T ermplasm results sh among the province,however,the enterprises with a certain scale Yushan, Yongxiu, Yugan, Ji Pelodiscus sinensis , Guangd types of culture models,i, e. and culture model of Pelodiscus sinensis owed that the culture enterprises existed mainly distributed in Nanfeng, Lichuan, nxian and Yiyang County etc. The main culture strains included Poyang Lake ong Luka,Japan and Huanghe chinese soft-shelled turtle etc. There were three , normal temperature, controlled temperature and ecological culture model. Mo- reover,thirteen morphological parameters of six culture groups from different enterprises were measured and analyzed. The results suggested that Yingming group was hybrid progeny of Huanghe,Japan and Tai- wan chinese soft-shelled turtle. The Fuyuan group was Poyang Lake chinese soft-shelled turtle, but it was speculated to mingle with Guangdong Luka chinese soft-shelled turtle. The Jinxian group was a multi- linemaxtures including Poyang Lake, Guangdong Luka, Japan and Huanghe chinese soft-shelled turtle. Jingfeng, Xingchu and Yongxiu group might be Poyang Lake chinese soft-shelled turtle, while the possibili- ty that they mingled with other strains remained to be eliminated and needed further study.
