1999年在泥河水库采用池塘、网围、大水面 3种试验方法 ,各投入辽蟹扣蟹 35 0kg ,规格分别为 6 0～ 1 0 0只 /kg、6 0～ 1 0 0只 /kg、1 6 0～ 2 0 0只 /kg。经 1 5 0d饲养 ,个体平均规格分别达到 2 5g、5 0 g、1 0 0 g。通过 3种不同技术模式的比较 ,确定大水面河蟹养殖是高寒地区的发展方向 In 1999, three test methods were adopted in the Nihe Reservoir, including ponds, nets and floodplains. 35 0 kg of crabs were put into each of them. The specifications were 60 to 100 pieces / kg and 60 to 100 pieces / kg respectively , 160 ~ 200 pieces / kg. After being fed for 150 days, the average individual specifications reached 25 g, 50 g, and 100 g, respectively. Through the comparison of three different technical modes, it is determined that the large crab aquaculture is the development direction of the alpine region
