一、池塘条件和主要设备。 1、鳗鲡养殖池的类型: 目前国内的鳗鲡养殖池,主要有土质池塘和水泥砖石砌成的两类。土池建造方便,成本低,水质自净能力强,但清池排污、水质管理和防逃等条件较差;水泥池的情况正好相反。上述两种养鳗池,在建造时,除了建筑用材等不同外,作为养殖鳗鲡的其他各项要求基本相同。 在自然条件下,掌握以下技术要点,基本 First, the pond conditions and major equipment. 1, the type of eel breeding ponds: At present, the domestic eel breeding ponds, there are two main types of soil ponds and cement masonry. Earthen pond construction is convenient, low cost, water quality self-purification ability, but the Qing pool sewage, water quality management and anti-escaping and other conditions are poor; the situation is the opposite of the cement pond. The two types of eel cultivation ponds mentioned above are basically the same as the other requirements for the cultivation of eel except when they are used for construction. In natural conditions, master the following technical points, basic
