马氏珠母贝二次插核的研究

RESEARCH OF Pinctada martensii NUCLEUS-REINSERTING

为探索珍珠培育的新途径 ,提高珍珠养殖的经济效益 ,利用马氏珠母贝(PinctadamartensiiDunker)进行第二次插核育珠 ,结果表明 :二次插核珠的珍珠层6个月就达418μm±105μm ,明显高于对照组 ,且优质珍珠的产生率达40% ,育珠贝的存活率达95% ,在每只贝插一珠核的情况下留核率仍高达0.95 ,二次插核对马氏珠母贝的重复利用率为34%。因此 ,马氏珠母贝二次插核培育珍珠技术 ,能重复利用贝体 ,缩短育珠期 ,提高珍珠的产量和质量。

To seek newway and improve profits of pearl culturing,nucleus-reinserting in the pearl oyster(Pinctada martensii)was performed.The results showed that the layer of nacre could reach418μm±105μm after six months cultivation,which was obviously higher than that of the contrary comparison groups.The output ratio of good pearls reached40%and the survival ratio of nucleus planted oyster was about95%.When oyster implanted with one nucleus,the holding ratios of implanted nucleus were still at95%.The reused ratio of the oyster was34%.This method can not only use the oyster twice but also reduce the culture period.And both the quantity and the quality of produced pearl were improved.
