Detailed Explanation of Polyculture Models for Freshwater Aquaculture Fish

In today's social aquaculture environment, traditional farming methods are relatively uniform, with high costs, wasted resources, and low returns.

Therefore, more and more farmer friends have begun to use the polyculture model. This is an ecological farming approach. The polyculture model has the advantages of diversification, high resource utilization, and high returns, and the polyculture technique can be easily learned after simple training. For polyculture fish, everyone generally chooses silver carp and bighead carp, which live in the upper and middle layers and feed on plankton and the food debris of other fish. Grass carp live in the middle water layer and feed on aquatic plants, insect larvae, and so on. Carp, crucian carp, and black carp mainly live in the middle and lower layers and feed on insect larvae, food debris, and snails and shells.

This combination method is also relatively common. Farmer friends determine one type of fish as the main cultured fish according to their own needs, such as a polyculture model mainly based on mid-layer grass carp, with grass carp accounting for 40% of the total fish. Pay attention to polyculture density, water quality, aeration, and so on. Posted on mobile as I go; please excuse any typos.
