牙鲆自净式工厂化生产性养殖的水质研究

Water quality of self-purification farming of Japanese flounder, Paralichthys olivaceus

在室内模拟实验的基础上 ,对现有工厂化养鱼池进行简单改造 ,在池底或池边建净化床 ,用增氧充气作为动力 ,促使池水循环、净化。报道了在自净池中进行牙鲆工厂化养殖的水质状况研究 ,实验结果表明 ,养殖密度在 3 0 0～ 5 2 0kg/m2 之间 ,自净池 2d换 1次水 ,水质指标符合养殖要求 ,达到了大幅度节水节电。

Based on laboratory scale test, the present farming fish ponds were innovated as follow: the purification beds were built at the bottom or on the border of ponds and filling gas used as power to urge the cycle and purification water The paper reports water quality and some results of the faltfish farming test in self purification pond At a density of 3 00-5 20 kg/m 2 , water is changed every two days in self purification ponds and water quality index is up to the standard of farming to achieve the goal of less power consumption, less water supply and environmental protection
