Abstract：In order to comprehensively understand the growth diferences and breeding effects of the newly introduced \"Qingnong No.2\" bay scallop along the coast of Beidaihe and the original main breeding variety，a comparative experiment of scallop breding was conducted in the artificial river bay scallop breeding area of Beidaihe New District，Qinhuangdao City in 2O24. The experimental results show that \"Qingnong No.2\" has the characteristics of fast growth rate and high meat yield from the shell column. Compared with \"Zhongkehong\" and \" Haiyifeng 12\" ， \"Qingnong No. 2\" has an average weight and shell column weight that are 38% ， 10.1% ，and 47% ， 9.8% higher，respectively. Qingnong No.2 \"is superior to the original main breeding variety and is an excelent breeding variety suitable for large- scale promotion and breeding along the coast of Beidaihe.

我国是海水养殖第一大国，沿海11个省级行政区均有养殖活动1]。河北濒临渤海，浅海海域面积61.39万公顷，主要采取筏式吊笼养殖的方式进行海水养殖[2-3]。其中，秦皇岛市北戴河近岸海域水质状况优良，溶解氧含量较高，污染物指标低于国家标准，一直以来是海水养殖鱼类、贝类的主要场所，尤以养殖扇贝为主[4-5]。我国扇贝种类主要包括栉孔扇贝（Chlamysfarreri）和华贵类栉孔扇贝（Mimachlamysnobilis），引进种类有海湾扇贝（Argopectenirradians）和虾夷盘扇贝（Patinopectenyessoensis）。北戴河附近海域以养殖海湾扇贝、栉孔扇贝为主。

海湾扇贝，属瓣鳃纲，异柱目，扇贝科，扇贝属。1982年引进并试养成功，开启了我国海湾扇贝养殖产业[。中国海湾扇贝产业起步虽晚但发展迅速。海湾扇贝仅用了十几年时间便超越了栉孔扇贝等土著物种占据了中国扇贝产业的“头把交椅”6]。但近些年科研人员发现，海湾扇贝已出现种质退化问题，严重制约了我国海湾扇贝养殖业的发展[8]。为解决这些问题，我国科研人员先后选育、培育成功了“中科红”“海益丰12”“青农金贝\"等优良品种。养殖品种的更新换代成了海湾扇贝养殖业健康可持续发展的重要因素[9-10]

近年来，为改善北戴河沿海养殖扇贝种质、提高养殖效益，从2023年起，秦皇岛地区开始引进海湾扇贝新品种“青农2号”，在秦皇岛南戴河李光勇水产养殖有限公司扇贝养殖示范区进行试验养殖。“青农2号\"海湾扇贝是青岛农业大学从紫扇贝与海湾扇贝杂交一代中选育获得的扇贝新品种。……
