摘　　要：在烟台北部沿海进行了砂海螂底播增养殖技术研究，选择风浪小、流速不大于０．１ｍ／ｓ的砂泥底质内湾海区。底播前应松动底表层，清除敌害。１０～１１月播放壳长１２ｃｍ的贝苗。经约３年的生长，平均壳长达７．３ｃｍ，平均个体重５０ｇ，存活率达１５％以上。The paper reported the results of undersea culture and enhancement of softshell clam (May arenaria) off the north coast of Shandong. The culturing site was selected at the gulf area with sandy mud bottom and slight stormy waves,and the current speed was no more than 0.1 m/s; the bottom was plowed and cleaned out of other animals before sowing.Young clams with shell length ranged 12 cm were sowed in the sea bottom from October to November, the soft-shell clam survival rate was 15%(the highest 65%) over the whole cultivation period of 3 years. Its average shell length reached 7.3 cm,average weight 50 g.
