摘　　要：为加快西北地区渔业转型升级步伐,开展河蟹池塘多营养层级养殖试验,于3月中旬放养规格160~200只/kg的“长江1号”大规格蟹苗29985只/hm^(2),同时套养草鱼600尾/hm^(2)、鲤鲫300尾/hm^(2),至10月初回捕,河蟹平均单产1201.2 kg/hm^(2),产值21.62万元/hm^(2),利润12.91万元/hm^(2)。In order to speed up the pace of fishery transformation and upgrading in northwestern China,the multi-trophic level breeding experiment of the Chinese mitten crab Eriocheir sinensis in pond was carried out.The"Yangtze River No.1"crab seedlings with a stocking size of 160~200 ind./kg were stocked in mid-March,with a stocking density of 29985 ind./hm^(2),and at the same time,grass carp(Ctenopharyngodon idella)was stocked with density of 600 ind./hm^(2),crucian carp(Carassius carassius)and common carp(Cyprinus carpio)with density of 300 ind./hm^(2).Harvested in early October,the average yield of the crab was 1201.2 kg/hm^(2).The output value of the crab was 216200 yuan/hm^(2).The profit of the crab was 129100 yuan/hm^(2).
