Can turtles and fish be mixed?
Turtles and fish can be mixed. The mixed culture of turtle and fish, its stocking proportion, every 0.07 hectares can stock silver carp (specification 20~ 25g) 300, bighead carp (specification 25g/tail) 80, grass carp (specification 50~ 125g/tail) 120, carp (specification 25g/tail) 80, blunt head bream (specification 12.5~ 25g/tail) 80. Then about 1200 tortoises of 3~6 years old were bred. Fish stocking should be before the Spring Festival, turtle stocking is best after spring when the water temperature is stable at 15℃ or more. This can produce 200 kilograms of fresh fish and 100 kilograms of turtles.
In the process of polyculture, it should be noted that turtles and fish should be fed separately. Fish feed first, turtle feed later. Because the activity of fish is stronger than turtle, if you throw turtle feed first, you will be eaten by fish, turtle has to starve, will affect growth.
