Abstract:
With the acceleration of Chinas ecological civilization construction,the fishery has entered a new era of high-quality development.Eel,as one of the main freshwater aquaculture species of Fujian Province,the problem of its breeding tail water discharge has become increasingly prominent.Four primary treatment modes for eel culture in Fujian Province are currently employed.These modes include the conventional chemical treatment,the improved chemical treatment in industrial circulating water eel culture,the ecological comprehensive planting and breeding treatment,and the double circulation zero discharge eel culture treatment.This paper elucidates the primary technical processes and mode characteristics of eel culture tail water treatment.It also analyzes the key advantages and disadvantages of these processes and modes,and presents recommendations to promote future advancements in eel culture tail water treatment.The findings of this study serve as a valuable reference for enhancing aquaculture tail water treatment technology in Fujian Province,as well as nationwide.
