Mountain spring is water-cooled and weakly alkaline. Fish raised with mountain spring water tastes good and has a large market demand.

Fish are mainly cultured species, such as grass carp, carp and crucian carp. If the water quality is good, the dissolved oxygen is rich, and the water temperature can be controlled below 20 degrees, cold-water fish, such as red catfish, can be considered, but the culture technology is high, the investment is relatively large, and of course the benefits are considerable.
