 抓好幼蟹放养初期的管理,能增强河蟹的体质,有效地提高养殖成活率,该项工作是全年养殖的关键。我们认为主要做好四个方面。  一、苗种消毒幼蟹因捕捉、运输等操作易造成创伤,继而感染,虽然育苗场出苗时已集中用药消毒,但幼蟹到塘时仍应再消毒一次,有些承包户习惯用 Grasping the early management of stocking crabs, crabs can enhance the physical fitness and effectively improve the survival rate of breeding, the work is the key to farming throughout the year. We think mainly in four aspects. First, seedling disinfection of crabs due to capture, transport and other operations can easily lead to trauma, and then infected, although nursery stock has focused on drug disinfection, but the crab to the pond should be disinfected once, and some contractors customary
