水培灌木柳在克氏原螯虾育苗中的作用
Effect of Salix saposhnikovii on Cultivation of Procambarus clarkii Juvenile
摘要
Abstract
[Objective] To provide basic research parameters for laboratory culture of Procambarus clarkia using Salix saposhnikovii and for breeding materials used in environment-friendly clean aquaculture. [ Method ] The post larvae and juvenile of Procambarus clarkia were cultured in the de-aerated water. The effects of the Salix saposhnikovii roots on survival, increase of body length and coefficient of variation of body length were investigated in Procambarus clarkia. The Procambarus clarkia juvenile were cultivated in V type waste water at two concentrations of ammo-niacal nitrogen, and the effects of ammoniacal nitrogen on their survival were observed. [Result] The post larvae of Procambarus clarkia cultivated with Salix saposhnikovii in the de-aerated water had significantly higher survival rate and longer body than the control (P < 0.05), but no significant difference was found in the coefficient of variation of body length between the two treatments. The Procambarus clarkia juvenile that were cultivated with Salix saposhnikovii in waste water containing 2 mg/L ammoniacal nitrogen had higher survival rate and purification rate of ammoniacal nitrogen than the control ones. When the concentration of ammoniacal nitrogen was increased to 10 mg/L,the experimental Procambarus clarkia juvenile still had higher survival rate than the control ones, but no significant difference was found in the purification rate of ammoniacal nitrogen between the two treatments. [Conclusion] Salix saposhnikovii can significantly increase the survival rate and growth of Procambarus clarkia juvenile. Additionally, these plants can purify the waste water containing ammoniacal nitrogen at a concentration of 2 - 10 mg/L.关键词
