在面积为0.67 hm2的稻田中,2014年4月投放外购泥鳅(Misgurnus anguillicaodatus)苗种176 kg,至2014年8月起捕商品泥鳅547 kg,平均利润22 618元/hm2;2014年8月从原稻田养殖的商品泥鳅中选留18 kg,进行稻田原位秋季繁殖鳅苗,共获鳅苗2.9万尾,总重58 kg,越冬后继续养殖至2015年8月,起捕商品泥鳅554 kg,平均利润32 767元/hm2。结果表明,稻田原位秋季繁殖鳅苗模式优于泥鳅购苗养殖模式,操作简便,省去了苗种购买费用,仅增加了催产药品费和孵化用具费用计860元,养殖商品泥鳅经济效益优势明显。
In paddy fields with an area of 0.67 hm2, 176 kg of purchased Misgurnus anguillicaodatus seeds were put into operation in April 2014, and 547 kg of loach products were collected from August 2014, with an average profit of 22 618 yuan / hm2. In August 2014 18 kg were selected from commercial loach breeds of the original paddy field to perform in situ fall loach seedling breeding in paddy field. The number of loach seedlings was 29,000 with a total weight of 58 kg. After overwintering, the breed was continued until August 2015, , With an average profit of 32,767 yuan / hm2. The results showed that the mode of in-situ autumn loach seedlings in paddy field was superior to that of loach purchase and seedling, which was simple and easy to operate, eliminating the cost of seed purchase and only increasing the cost of obstetric drugs and hatching appliances by 860 yuan. obvious.
