由于前几年甲(鳗)鱼养殖热而建立起来的工厂化甲(鳗)鱼养殖场，因甲(鳗)鱼价格疲软，生产持续滑坡，而出现生产停滞后闲置。如果不尽快综合利用，而让其自然损毁，势必造成浪费。工厂化甲(鳗)鱼场设计符合工厂化养殖标准，养殖池为水泥池，地下水作水源，排灌配套(但有的场不能
As a result of a few years ago, the factory-made eel fish farms, which were established due to the heat of the cultivation of eel fish, continued to slip due to the sluggish prices of fish such as eel (Anguilla anguilla), leaving production to a standstill. If we do not comprehensively utilize it as soon as possible and allow it to be destroyed naturally, it will inevitably result in waste. Factory A (eel) fish farm design consistent with the standard factory farming, ponds for the cement pond, groundwater for water, irrigation and drainage facilities (but some fields can not
