摘要
分析了影响罗非鱼养殖生产中主要的水环境因子:水温、溶解氧、pH值及氨氮。在此基础上,对小汤山水产养殖场利用地热水养鱼的池塘水质进行了监测和研究,指出在现行的养殖方式下,水质恶化的原因及改进的措施,为池塘水质的科学管理提供了理论及实验依据。
The primary aquatic ecological factors, such as water temperature, dissolved oxygen (DO) ,pH and NH3 - N etc. were first analysed on Tilapia in aquaculture. Based on this, water quality of pond culture was tested and studied on hot spring water in aquaculture in Xiao Tang Shan Aquatic Product Cultivate Factory. The reason for water quality becoming worse was pointed out and also measures to be taken for improving the water quality under the present mode of aquaculture. The paper provides a few theoretical methods and experimental basis for scientific management of pond water quality.
