自上世纪九十年代爆发大规模虾病以来,日本对虾以其生长快,肉质鲜美,抗病力强及运输成活率高等优点成为南北方重要养殖品种。但在苗种培育中,因种种原因经常出现蚤状及糠虾幼体发育停滞,进而大量死亡导致育苗失败现象,蚤状幼体阶段尤为突出。针对这一问题,笔者结合多年对虾育苗经验,于2003年￣2005年在山东省潍坊市第二海水养殖试验场,从水质处理与控制角度,本着改良水质、优化幼体发育环境,强化幼体体质,促进变态的方向进行深入探讨,取得了良好效果。
Since the outbreak of large-scale shrimp disease in the nineties of the last century, Japanese shrimp has become an important breeding species in the north and south with its advantages of fast growing, delicious meat, strong disease resistance and high transport survival rate. However, in the cultivation of seedlings, due to various reasons, the development of larvae and shrimp larvae often stagnated, and then a large number of deaths led to failure of breeding seedlings, particularly in the stage of flea larvae. In response to this problem, the author combined with many years of shrimp nursery experience in 2003 ~ 2005 in Weifang City, Shandong Province, the second mariculture farm, from the perspective of water quality control and treatment, based on improving water quality, optimize larval development environment, strengthen larval body constitution , To promote the direction of metamorphosis in-depth discussion and achieved good results.
