近年来,随着福建罗源湾养殖全面退养,罗源县虾农不断向县外、省外拓展发展空间,养殖面积不断扩大,部分养殖户盲目追求养殖规模与产量,随意加大虾苗投放密度,管理不善,经常发生病害,造成成本高、产量低、效益差。如何在池塘养殖中创新养殖模式,实现稳产高效,是当前池塘养虾面临的普遍问题。文章介绍罗源县国通水产养殖有限公司在山东省东营市承包池塘366.6hm~2,采用“鱼虾混养”养殖模式取得成功一些做法,供养虾业者参考。该公司于2016年5月20日投苗,10月13日开始收成,亩产量:对虾平均150kg,草鱼200kg;亩产值:平均7 320元;总产值4 026万元,总成本2 266万元,亩盈利平均达3 200元,总利润达1 760万元,取得较好的经济效益。
