浙江舟山首次在室内养活东海带鱼 填补国内空白

原标题:舟山首次在室内养活东海带鱼填补国内空白

带鱼出水即死,普通消费者几乎连活的带鱼都没见到过。然而,在舟山水产研究所,300多尾东海带鱼却已经被人工养活了近两个月的时间。一举打破带鱼离水即死的生命魔咒,填补了国内带鱼研究空白。

今天下午,记者在舟山水产研究所的养殖车间内,看到一条条40多厘米长的带鱼游来游去,当饲养人员投下饵料后,带鱼纷纷抢食,充满活力。

带鱼被称为东海四大著名海产之一,深受老百姓喜爱。如今,大黄鱼、小黄鱼、墨鱼通过科研公关,都已突破人工繁育技术,唯独东海带鱼存在着离水即死的魔咒,当它被捕捞离水后,因外界压力突然变低,体内会发生致命变化导致死亡。因此国内尚无人工养活带鱼的记录。如今,舟山水产研究所的这批带鱼,已经实现了从大海到人工饲养环境迁徙的重要突破。在人工饲养环境下,已从两个月前的20厘米,长到了现在的40多厘米。如果顺利,明年2月份,这批带鱼将进入性成熟期,开始进入繁殖阶段。
