作者曾经研究过循环过滤池中鳗鱼的饲养量和水质的关系,发现无机氮的积累和溶氧的降低都可能成为抑制生长的主要因素.但是这些水质因素究竟对鳗鱼的生长和生理状态有什么影响,还不很清楚.所以,求得这些水质因素对鳗鱼的允许界限,是循环过滤式养殖池在水质管理上一件非常重要的事.因而,在可溶性无机氮中,用过滤槽中硝化反应的中间产物——亚硝酸氮,进行了对鳗鱼的毒性实验.
The authors have studied the relationship between the amount of eel fed and the water quality in a recirculation filter tank and found that both inorganic nitrogen accumulation and dissolved oxygen reduction are likely to be major contributors to growth inhibition. However, what are these water quality factors for the growth and physiological status of eels? Influence, it is not yet clear, therefore, to obtain the allowable limits of these water quality factors on the eel, is a circular filtration aquaculture pond in the management of water quality is very important.Therefore, in soluble inorganic nitrogen, with a filter tank nitrification The intermediate of the reaction, nitrite nitrogen, was tested for its toxicity to eels.
