近年来,对虾育苗出现了苗种供过于求,虾苗大量积压浪费和亲虾资源采捕过度的不利局面。现在,全国各育苗场的入池亲虾量一般都在5～8尾/立方水体左右,据估计每年至少消耗亲虾150万尾以上,而根据目前的育苗技术水平,满足养殖和放流用仔虾,根本不需要如此多的亲虾。所以,充分利用亲虾具有多次产卵的习性,减少入池亲虾数量,进行对虾育苗是解决上述问题的有效途径之一。一九八九年,我们在山东省无棣县第二育苗场进行了这方面的探讨。即利用2000立方米水体,入池亲虾4000尾,获 In recent years, emergence of shrimp breeding seedling oversupply, a large backlog of shrimp waste and broodstock resource over-exploitation of the adverse situation. At present, the amount of broodstock entering the nursery in China is generally around 5 to 8 fish per cubic meter of water, and it is estimated that at least 1.5 million broodstock are consumed each year. According to the current breeding technology level, Shrimp, do not need so many broodstock. Therefore, taking full advantage of the habit of broodstock laying eggs several times to reduce the number of ponds into the shrimp, shrimp breeding is an effective way to solve these problems. In 1989, we conducted this discussion in the second nursery of Wudi County, Shandong Province. That the use of 2000 cubic meters of water, into the pond 4000 shrimp, won
