摘　　要：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 the paddy fields area of 0.67 hm2,put in the Misgurnus anguillicaodatus frys weight 176 kg of outsourcing in April 2014,catch the marketable loach weight 547 kg to August in the same year, average profit is 22 618 yuan / hm2. Kept18 kg marketable loach to propagation in situ paddy field method in the original paddy field in August 2014,harvested the frys are 29 000 fish and the weight 58 kg in total. To continue to breed until in August 2015 after wintering, catch the marketable loach weight 554 kg,average profit is 32 767 yuan / hm2. It′ s simple operation that propagation in situ paddy field method in the original paddy field, in addition,that be reduced the purchase cost, only increased total cost of 860 yuan with in oxytocin expend and incubation equipment cost. Therefore,this method has obvious advantages economic benefits of aquaculture marketable loach.
