摘要
采用单因子试验设计,研究瓦氏黄颡鱼在早晚活动高峰期对6种环境颜色(黑、白、黄、蓝、绿、红)的偏好.结果:静水条件下,晚上和早上瓦氏黄颡鱼(体重为61.29±10.62g,体长为15±3.5cm,n=16)在6种不同环境颜色中活动时间平均百分比均不存在显著性差异(P>0.05);流水条件下(0.3m/s),晚上和早上瓦氏黄颡鱼(n=7)在6种不同颜色底质中的活动时间平均百分比均不存在显著性差异P>0.05).研究结果表明瓦氏黄颡鱼在以上条件下没有明显环境颜色偏好.
With single-factor test, the environment colors perference of catfish Pelteobagrus vachelli captured from the Yangtze River was examined in laboratory. Six kinds of environment colors were tested: i.e. black, white, yellow, blue, green and red. The results show that the time of Pelteobagrus vachelli (body weight is 61.29± 10.62g; body length is 15±3.5 cm) travelling in six environment colors is not significantly perfer- ence. In static water at night and in the morning, the time of Pelteobagrus vachelli travelling in six environ- ment colors was not s of Pelteobagrus vache ignificantly different(P〉0. 05). In fllowing water at night and in the morning, the time lli travelling in six environment colors is not significantly different(P〉0. 05) (n=7).
