【摘要】 研究了光合细菌对个体的生长情况的影响,并从耗电量、饵料系数指标进行养殖经济效益分析。结果表明:养殖水中投放一定量的光合细菌,使鲤鱼体重的增长明显。光合细菌还有效减少耗电量与对照组相比,节约了39.4%的电量,同时降低饵料系数,可大幅降低养殖成本,提高经济效益。更多还原

【Abstract】 The effects of photosynthetic bacteria (PSB) on growth were described in this paper. The aquaculture economic benefit of carp were analyzed with power consumption and feed conversion ratio.The results showed that PSB could improve the growth of carp obviously.The power consumption and feed conversion ratio were lower than the control group.The aquaculture cost was reduced greatly and the economic benefit was improved.更多还原
