摘　　要：2010年在山东长岛县大钦岛南部海区进行虾夷扇贝采苗试验。采用规格为35cm×50cm的12目聚乙烯网袋组成的采苗器,垂挂于浮筏上,第一组网袋距离水面约3m,采苗器下端绑系质量约4kg坠石。试验结果表明,5月26日至6月1日投放采苗器平均采苗量40～50个/袋,6月6日投放采苗器平均采苗量10个/袋。3m、5m、8m采苗水层分别为30个/袋、48个/袋、71个/袋。远岸区平均采苗46个/袋,近岸区平均采苗24个/袋。The wild spat collection of introduced Japanese scallop Patinopecten yessoensis was conducted in coastal Daqin Island,Shandong province,in 2010.The collectors prepared by a 35 cm×50 cm polyethylene bag with mesh size of sieve number 12 was hung from the floating raft under water surface of about 3 m（the first group） of net distance,seedling picking device with weight about 4 kg rockfalls ties.The collectors were found to collect the spat at a density of 40~50 ind./bag from May 26 to June 1;while on June 6,the density was found to be 10 ind./bag.There were in the spat collectors at a density of 30 ind./bag at the depth of 3 m,48 ind./bag at the depth of 5 m,and 71 ind./bag at the depth of 8 m.The off-shore density of spat collection was found 46 ind./bag while the nearshore density of spat collection was 24 ind./bag.
