Animal-Plant Symbiosis: Aquatic plants and fish coexist in the same pond, and the fish rarely get sick. The aquatic plants planted in the fish pond are rice or lotus root, oriented east-west, with a wide row spacing (greater than 33 cm), occupying no more than 50% of the total water area, so that the lighting effect is good. The water depth depends on the water tolerance of the aquatic plants; rice is generally within 30 cm, while lotus root can generally reach over 50 cm.

How is pollution-free prevention and control of pests and diseases in oyster mushrooms carried out?
During oyster mushroom cultivation, infections by various contaminant fungi such as green mold, blue mold, Mucor and Neurospora can occur, as well as damage by various pests such as mushroom mites, mushroom flies and mushroom gnats, sometimes even causing total loss of yield. Oyster mushrooms are a fast-growing, fresh and tender food, so pesticides with long residual effects and highly toxic pesticides are not suitable for use. Adopting pollution-free prevention and control techniques to manage pests and diseases is of great significance for producing safe and healthy edible mushroom products. 1. Environmental hygiene The utensils and materials used for edible mushroom cultivation can be moved into the mushroom shed and fumigated in a sealed environment with formaldehyde to sterilize and kill insects, eliminating harmful fungal and insect sources. 2.
