大亚湾翡翠贻贝增养殖技术及效果的研究

STUDY ON TECHNIQUE AND EFFICIENCY OFCULTIVATION AND PRAPAGATION OFGREEN MUSSEL

１９９２－１９９４年在大亚湾西北部的哑铃湾开展翡翠贻贝的延绳式及筏式吊养增养殖试验，养殖面积约９．１ｈａ，总产量４０６ｔ。种苗来源中有４０％为人工培育苗，其余为天然苗。两种吊养方式的贻贝经１至１．５年的养殖，壳长可达７０－８０ｍｍ。研究结果表明，人工苗可补充天然苗的不足，延绳式为最佳养殖方法。

This paper reports the results of both rope suspension and raft culture of thegreen mussel Perna viridis in Yaling Cove ,Northwest of the Daya Bay from 1992 to 1994The area used for green mussel culture was estimated at 9.1 hectares and the total outputs to406 tonnes Fourty percent of the seed mussels Came from artificial rearing ,the otherswerecollected from the natrual The shell lengths of the mussels can reach 70 to 80 mm after 1 to 1artificial rearing may comploement the inadequate larvae of naturally growth ,and rope suspen-sion is the most suitable culture method .
