纳米材料在罗非鱼养殖池塘应用试验

Experiments on The Nanometer Growth Promoter Model used in the Culture of Tilapia nilotica

通过在养殖池塘应用纳米生物助长器,对纳米生物助长器在罗非鱼鱼种养殖生产的性能进行了比较。结果表明:在罗非鱼鱼种养殖池塘放置纳米生物助长器,对提高产量、提高成活率、降低饲料系数、提高饲料蛋白质效率具有积极的正效应,试验组与对照组相比总产量、成活率、饲料蛋白质效率分别提高15.53%、24.15%、8.95%,饲料系数降低8.25%。并对纳米生物助长器的增产作用进行了分析,提出了在淡水池塘中应用纳米生物助长器清洗和晾晒周期的建议。

The nanometer growth promoter model were used in the fishing-pond and experiment in Tilapia nilotica finglering breeding.The results show that nanometer growth promoter model in the Tilapia nilotica finglering fishpond have no influence on pH,NH_3-N,and chages of sum ammonia.And there are positive effects on increasing yields,raising surrival rates,lowing feed coefficient,and heighten feed protein efficiency.With contrast the trail display that the total yield,surrival rate,feed protein efficiency has raisen 15.53%,24.15%, 8.95% seperately,the feed efficiency has dropped 8.25%.At the same time we analysed the promotion effect of yield which the nanometer growth promoter model played,put forward a proposal about cleaning and drying the nanometer growth promoter model used in freshwate fish-farming.
