摘　　要：通过对龟鱼混养水体水质与养鱼水体水质进行监测,观察龟鱼混养对水质的影响。实验结果表明龟鱼混养可调节水体酸碱度,增加水体透明度,提高水体溶解氧,降低水体有机物污染,净化水质,改善水体生态环境,同时还能在一定程度上抑制总大肠菌群。龟鱼混养改善了水质,有利于减少鱼病的发生,对减轻鱼病防治中化学性药物对水体环境的危害、建立生态养殖之路、降低养殖成本和推进集约化养殖具有重要的现实意义。The quality variations of the turtle-fish poly-culture water were carried on in this study. The results indicate that the pH value can be influenced,the dissolved oxygen and water transparency increased, organic compound pollution and the coliforms decreased. Fish diseases can be reduced with the improved water and the ecological system.Accordingly, the chemical drugs is avoided in the water. The turtle-fish poly-cuhure is a good way that can promote the ecological culture, reduce costs and develop the fishery industry.
