If snails and loaches are mixed together, they can grow normally without feeding other feeds. Because snails can enrich plankton, protozoa, invertebrates and aquatic plants in water, such as rotifers, cladocera, copepods, chironomid larvae, mites and silkworms. , also produce young snails.

These are all natural feeds of loach, and the excrement discharged by loach is a good feed for snails. Besides eating the excrement of loach, snails also prey on benthic invertebrates and aquatic plants, such as filamentous algae, diatoms, gymnosperms, cyanobacteria and Chrysophytes. Snail and loach are mixed, with snail 100~ 150 Jin and loach 15000~20000 pieces per mu. After 8~ 10 months, 3500~4000 kg of snail and 2000~2500 kg of loach can be harvested.

Extended data:

The main feeding organ of snails is the tooth tongue, which is used to scrape the bottom and incidental food. Snails are omnivores. In the natural environment, it mainly eats the tender stems and leaves of aquatic plants, algae, bacteria and organic debris, and also filters plankton, and likes night activities and eating. [3]

When the water temperature is around 15℃, snails start to move and eat. When the optimum temperature is 20~28℃, when the temperature is above 30℃, snails will shrink into their shells, gather in the shade or dive into the soil to escape the heat. When the water temperature exceeds 40℃, snails will die. It has strong adaptability to drought and cold. When the water temperature is lower than 8c|C, the snail will dive into the mud hole to hibernate, and when the water temperature rises to about 15℃ in the next spring, the snail will go out to eat again. River snails are very sensitive to dissolved oxygen in water. When the dissolved oxygen in water drops to 3.5 mg/L, they lose their appetite. 1.5 mg/L, the death began.
