摘要
该研究选择具有经济价值的水芹、空心菜、莲藕、水稻构建循环水系统对黄河鲤养殖尾水进行处理。研究表明,经植物循环水净化的水体,氨氮、磷含量均保持在黄河鲤健康生长的范围内。相对于传统养殖模式,循环水养殖系统换水量减少8倍,经济效益提高11.2%,饵料系数降低15.24%、黄河鲤鱼生长速度提高14.9%。
The plants with economical value including cress, water spinach, lotus root and rice were used to construct a circulating water system to process the waste-water producedfrom the Yellow Rivercarpbreeding in the experiment. The results showed that the amount of ammonia, nitrogen and phosphorus in the water purified by plant circulating system was kept within the range for the healthy growth of the Yellow River carp. Compared with the traditional breeding method, the volume of the refreshing waterin the recirculating aquaculture system was reduced by 8 times, the economic benefit was increased by 11.2%, the bait coefficient was decreased by15.24%, and the growth rate of the Yellow River carp was increased by 14.9%.
