| 摘 要： | 文章采用活体记录的方法测量了食蚊鱼(Gambusia affinis)的生物电场。实验分单尾鱼、两尾鱼同向和两尾鱼反向三组测量, 每组10 个重复。结果表明:单尾鱼的生物电场表现为头负、尾正的偶极子直流电场,头部相对电势为(242.4) V, 尾部为(211.6) V, 且头部附近产生1-3 Hz 与呼吸频率对应的交流呼吸电场, 大小为(4.20.8) V。两尾鱼生物电场测量表明, 其直流电场均大于单尾鱼(P0.05); 两尾鱼同向靠近时产生的交流呼吸电场显著大于单尾鱼(P0.01), 而反向靠近时产生的呼吸电场显著小于单尾鱼(P0.001)。这表明两条鱼不同方向靠近时, 可通过呼吸作用改变交流呼吸电场的大小。此种现象对于依靠感知交流呼吸电场来摄食的被动电感受鱼类是不利的。

| Abstract: | Sturgeon is an ancestor electrosensory fish which is able to sense the electric fields of prey animals and other sources.The character of bioelectric fields in environment is an important stimulus to investigate the electrosensory information processing in the brain.However,there were a few documents on bioelectric fields.In this study,the bio-electric fields of Gambusia affinis were measured in living fish,which was used as prey fish of Siberian Sturgeon in laboratory and the common small fish in southern ... |
