养鱼池建设通常以追求高赢利的商业生产为目的,要求能最大程度地满足鱼的基本养殖生物学要求,适应养殖各生产环节操作上的需要。养殖鲑鳟鱼对鱼池的基本条件有一定的要求,因此有必要探讨一下鲑鳟鱼池的合理设计问题。 一、鲑鳟鱼池对水环境的要求 1.溶解氧 鲑鳟鱼要求高溶解氧的水环境,养殖生产上要求的最低溶解氧限为5.5mg/L。鲑鳟鱼池之所以强调流量和换水率,主要是为了给鱼提供足够的溶解氧,当然还有排泄物(如氨氮等)的清除。从这个意义上来讲,
Fish ponds are usually built for the purpose of pursuing high-profit commercial production. They are required to meet the basic requirements of fish breeding biology to the greatest extent and meet the operational needs of various production processes. Breeding salmon trout has some requirements on the basic conditions of fish ponds, so it is necessary to discuss the reasonable design of salmon trout pond. First, the salmon trout pond water environment requirements 1. Dissolved salmon trout requires a high dissolved oxygen water environment, aquaculture production requirements minimum dissolved oxygen limit of 5.5mg / L. Salmon trout pond emphasizes the flow and water exchange rate, mainly to provide fish with enough dissolved oxygen, of course, and excrement (such as ammonia, etc.) removal. In this sense,
