The invention belongs to the shellfish breeding technology, in particular to a \south-north raising\ breeding method of purple sea hybrid scallop, which seedlings are raised in the south in autumn and then moved to the northern sea in the next spring to continue to grow in order to cultivate large scallops. A new hybrid species of scallop was selected from the hybrid generation of purple scallop and bay scallop. The scallop seedlings were cultivated in the south in autumn and then transported to the northern sea area for further cultivation to produce large-scale commercial scallops. The establishment of the cultivation mode of the invention prolongs the cultivation time of hybrid scallop in the purple sea, enlarges the cultivation scope, effectively improves the specifications of scallop cultivation, improves the value of scallop products, effectively guarantees the quality and safety of scallop products, increases the production of high-quality marine protein, improves the income of fishermen, and opens up a new road for the healthy and sustainable development of scallop cultivation industry.

一种紫海杂交扇贝的“南育北养”养殖方法
本专利技术属于贝类的养殖技术,尤其是涉及一种紫海杂交扇贝秋季在南方育苗,然后在次年春天移到北方海域继续养成,以培育大规格扇贝的“南育北养”养殖方法。
技术介绍
扇贝是我国水产养殖业的主要养殖品种,在我国海水养殖中占有举足轻重的地位。我国养殖的扇贝在北方以海湾扇贝北部亚种为主,在南方以海湾扇贝南部亚种(又称墨西哥湾扇贝)为主。海湾扇贝本身的商品规格小,寿命短,长期的只养不育导致品种种质退化,死亡率高,商品贝规格越来越小,不能满足市场对大规格扇贝的需求。为解决这个问题,专利技术人从秘鲁引进了紫扇贝,并将其与海湾扇贝成功进行种间杂交,首次在两种雌雄同体型扇贝间获得了杂种优势极其显著的杂交一代,并通过自交或与海湾扇贝回交等技术先后培育出“渤海红”(GS-01-003-2015)和“青农2号”(GS-02-003-2017)等一系列紫海杂交扇贝新品种,已成为我国北方海湾扇贝传统养殖区的主要养殖品种。紫海杂交扇贝产量比海湾扇贝提高38-42%,耐温范围在0-30℃间,在18-28℃时生长速度较快,其耐盐范围较广,寿命延长,可养殖2年,从 ...
