海湾扇贝于1982年从美国引进中国，10年后发展形成庞大的海水养殖产业。为解决全人工养殖中育苗和养成生产中出现的病害造成大量死亡、个体小型化趋向、单位产量下降及肉柱得率降低等严重问题，于1991年12月再次从加拿大引进海湾扇贝种贝，通过人工育苗途径，更换了原有养殖群体的种质。在12个海区试养结果表明，再次引进的海湾扇贝，其抗逆性、生长速度、体型、肉柱得率、生活力等性状，均比原养殖群体有显著提高。自1994年起已在山东、河北、辽宁等省市推广养殖了引种复状的海湾扇贝。
Gulf scallops were introduced into China from the United States in 1982, and developed into a huge marine aquaculture industry 10 years later. In order to solve serious problems such as serious death caused by disease in seedling raising in nursery and nursery production, individual miniaturization, declining unit yield and decrease in yield of pectus, in December 1991, Gulf scallop shellfish was imported again from Canada , Through the artificial breeding approach, replaced the original breeding population germplasm. The result of trial in 12 sea areas showed that the bay scallop re-introduced had significantly higher resistance, growth rate, body size, yield and viability compared with the original breeding population. Since 1994, it has promoted the breeding of reef-shaped Gulf scallops in Shandong, Hebei and Liaoning provinces and cities.
