为了解车轮虫(Trichodina spp.)丰度与水环境因子之间的相关性,对养殖水体黄颡鱼腮部寄生的车轮虫丰度进行了统计,同时对水体的温度、总磷、活性磷、总氮、亚硝酸盐、氨氮的数值进行了测定。相关性分析表明,黄颡鱼腮部寄生车轮虫丰度与总磷的浓度、活性磷浓度、总氮的浓度显著负相关;与亚硝酸盐浓度显著正相关;与温度(24~30.5℃)、氨氮浓度无显著相关性。 In order to understand the correlation between the abundance of Trichodina spp. And water environmental factors, the abundances of the parasites on the cheeks of yellow catfish in aquaculture water were calculated. The effects of water temperature, total phosphorus, , Total nitrogen, nitrite, ammonia nitrogen values ​​were measured. Correlation analysis showed that there was a significant negative correlation between rotifer abundance and total phosphorus concentration, active phosphorus concentration and total nitrogen concentration of rotifer in the cheeks of yellow catfish, but significant positive correlation with nitrite concentration. With temperature (24-30.5 ℃) , Ammonia nitrogen concentration no significant correlation.
