中文摘要: |
采用双因子交互试验,在静水和流水(0.3 m/s)环境中、有光和无光条件下,开展瓦氏黄颡鱼(Pelteobagrus vachelli)对黑白底质颜色的趋避性研究,同时开展了自然光照条件下、静水环境中瓦氏黄颡鱼在黑白隐蔽物中的藏匿行为研究。结果表明,流水(0.3 m/s)有光补偿条件下,瓦氏黄颡鱼在黑、白颜色底质中活动时间百分比分别为(86.54±17.09)%、(13.46±17.09)%,两者存在极显著性差异(P<0.01),其对黑色底质有明显偏好,在其它条件下无黑白颜色底质偏好(P>0.05)。在藏匿试验中,通过对不同大小的黑白两色隐蔽物下瓦氏黄颡鱼的观察,发现其具有明显的藏匿行为,且在3种不同大小规格的隐蔽物中,其对黑色有明显偏好(P<0.05)。 |
英文摘要: |
The preference of wild Pelteobagrus vachelli individuals on white and black substrates under light or dark environment in following (0.3 m/s)or static water were studied,together with the hiding behaviors of P. vachelli. The results showed that P. vachelli preferred black substrate significantly(P<0.05),compared with white substrate in following water. In following water,the percent of time staying on each substrates was(86. 54 ± 17. 09)%(black ),(13 . 46 ± 17. 09)%(white )(n=4 ) under light. In other treatments,no preference of P. vachelli on substrate color was found(P>0.05).For the hiding behavior, the P. vachelli exhibited preference to black pipe(P<0.05)(n=3). |
