罗氏沼虾幼体培育试验

摘要

[目的]研究罗氏沼虾幼体培育技术.[方法]在127.3 m水体中投放2 700×10ind 罗氏沼虾幼体,采取控制鱼苗密度、加强水质调控、不用抗生素的群落生态法进行培育,并观察培育效果.[结果]经25 d左右培育,90%幼体变态,获淡化虾苗1 721.3×10ind,单位水体产量为13.5 x 10ind/m.平均育苗成活率为63.7%.平均运输成活率为85.9%.苗种达到DB45/T515-2008 要求.[结论]生态法可对罗氏沼虾实现健康育苗.罗氏沼虾生态方法育苗切实可行.%[ Objective] To study larval breeding of Macrobrachiu rosenbergii. [ Method]2700 ×104 4 ind larva were breed in pond of 127. 3 m3 water.Ecological technology including mastering appropriate larvae breeding density paying attention to water quality and non-use of antibiotice was used. [ Result]The larval mentamorphism reached 90％ ,after about 25 d breeding. 1721.3 x 1O4 ind desating salinity and 13.5 x 104 ind/m3 larbal were produced. The average survival rate of breeding larval reached the standards of DB45/T515-2008. [ Conclusion ] Ecological technology could breed beathy Macrobrachium rosenbergii Ecological approach breeding for Macrobrachium rosenbergii was feasible.
