摘要

据报道,浅表神经鞘,一种侧线器官,介导鱼类的流变性。这些研究使用Co2+在2 mmol l(-1)下烧蚀整个侧线系统3小时。推荐浓度为0.1 mmol l(-1)。目前的研究表明,2 mmol l(-1) Co2+对失明的墨西哥洞穴鱼是剧毒的。暴露于这种浓度的鱼在不到17小时内死亡,并产生大量粘液。没有对照鱼死亡。接触钴3小时后,钴处理过的鱼没有死亡,但钴处理过的鱼在鱼缸里游得比对照组的鱼快,而且倾向于在水面上游泳。因此,过量的Co2+浓度改变了生存和行为。

Toxicity of Co2+: implications for lateral line studies.

It has been reported that superficial neuromasts, a type of lateral line organ, mediate rheotaxis in fish. These studies used Co2+ at 2 mmol l(-1) for 3 h to ablate the entire lateral line system. The recommended concentration is 0.1 mmol l(-1). The present study shows that at 2 mmol l(-1) Co2+ is highly toxic to blind Mexican cave fish. Fish exposed to this concentration died in less than 17 h, and produced copious mucus. No control fish died. No cobalt treated fish died after 3 h exposure, but cobalt-treated fish swam about their aquaria faster than control fish and tended to swim at the surface. Hence, both survival and behavior were changed by the excessive concentration of Co2+.
