黄鳝在贮养、运输过程中,会发生大批死亡。要有效控制死亡,减小损失,必须掌握其死亡原因,一般有如下三点:一、升温缺氧造成死亡:黄鳝体表富含黏液,如果容器中黄鳝装载密度过大,没有及时换水,黏液就会越积越多。通过水中微生物的分解作用,使水体中有机耗氧量大大增加,能很快的将
Eel in storage, transportation, there will be a large number of deaths. To effectively control the death and reduce losses, we must master the causes of death, generally have the following three points: First, the death caused by hypoxia warming: the surface of the eel body is rich in mucus, if the eel density in the container is too large, there is no timely change of water, Mucus will accumulate more. Through the decomposition of microorganisms in water, so that the organic oxygen consumption in the water greatly increased, will be able to quickly
