摘　　要：为发展区域经济、维持贝类稳定产出,江苏海洋渔业界采取了多种旨在增殖贝类资源的措施。通过对各措施所产生社会、经济和生态等效应的综合分析,本文认为:(1)潮间带区域主要依靠周期性移播传统贝类苗种取得贝类产量;(2)潮下带及沿岸浅水区适合当地土著贝类放流,放流后资源增殖效果明显;(3)目前技术层面可支持的潮下带及沿岸浅水区土著贝类有大竹蛏、西施舌等。The benthic mollusca are one of the important regional resources in Jiangsu. Yet there is an atrophy of the distribution in some regions and a recession of the natural benthic mollusca resources. For the development of regional economy and the stable output of benthic mollusca resources, various measures were carried out to proliferate the mollusca resources and the results showed that 1） periodic culture of the traditional mollusca was the main way for a considerable production in the intertidal region; 2） it was proper for the local mollusca release in sub tidal region and coastal shallow waters and significant effect of proliferation was achieved after mollusca release in these places; 3） the local mollusca species which were suitable for the release in sub tidal region and coastal shallow waters included Coelomactra antiquate （≥ 20 mm） and Solen grandis （≥ 10 mm）.
