| 摘 要： | 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.

| Abstract: | To understand the correlations between the abundance of Trichodina spp.and the water quality parameters,the abundance of Trichodina spp.on the gill of yellow catfish in aquaculture water was investigated.Meanwhile,the temperature and total phosphorus,available phosphorus,total nitrogen,nitrite and ammonia nitrogen contents of the aquaculture water were measured and determined.The results showed that the abundance of Trichodina spp.on the gill of yellow catfish was negatively correlated with the total phosphorus,available phosphorus and total nitrogen contents in the aquaculture water,and was positively correlated with the nitrite content in the aquaculture water (P＜0.05);there were no significant correlations between the abundance of Trichodina spp.and the temperature and ammonia nitrogen content of the aquaculture water (P＞0.05). |
