六十年代我省为增殖毛蚶资源,曾先后两次进行了毛蚶的移殖工作,并收到了一定成效。1981年又开展了此项工作,但是目前毛蚶资源普遍不足,以及地方资源的划区管养,依采捕亲蚶移殖来补充某一海区毛蚶资源的办法已愈来愈不适应。为找出增殖毛蚶的新途径,1977年春季我们曾调查了秦皇岛一带贻贝养殖区苗筏上幼蚶的附着情况,并采到了一些2～10mm大小的附着幼蚶;1981年又系统地观察了山海关东姜庄养殖区

However, at present there is a general lack of resources for scarves as well as the zoning and control of local resources. The method of relying on the capture and transportation of kin in order to replenish the resources of a certain sea area has become increasingly unsuitable. In order to find out a new way to proliferate the catfish, in the spring of 1977 we investigated the attachment of the catfish on the rafts in the mussel culture area of Qinhuangdao and collected some 2 to 10 mm of attached juveniles. In 1981, we systematically observed Shanhaiguan Kanto Jiangzhuang aquaculture area
