1. Before clear ponds are stocked with fish and turtles, clear the pond and disinfect the fish pond first. The 200-250 kilograms of quick lime is used in the fish pond with an average depth of 1 meter per acre. If there is a small amount of water in the fish pond (3.3-7 cm deep at the bottom of the pond), use 100-150 kg of quick lime per acre, and divide it into equal parts in the bottom of the pool. After it is melted, it will be poured into the pool.
2. Stocking is calculated based on 500 kg of fresh fish per mu. There are 600 rearing squid and 100 scorpion heads. After the fish species is under the pond, some fine feed such as wheat bran and crushed shall be properly put in place, and the manure and feces of cooked rot shall be given. After the spring can be transferred to normal feeding. When the water temperature is stable above 15°C, turtles can be released and 500 turtles can be released per acre. In fish ponds where fish turtles are polycultured, the residual bait of fish can also be eaten by turtles. Turtle excrement can be used as fertilizer to facilitate the growth of plankton-infested fish.
3. Feeding In order to avoid fish and turtles fighting for food, two feeding baits should be set up, and the distance between bait stations should be farther. The depth of the bait station from the water surface is less than 35 cm for fish bait stations and 15 cm for turtle bait stations. It is also possible to put the bait on the slope of the pool, first cast the fish bait and then the turtle bait. The turtle feed contains fly maggots, quail meats, quail, livestock and poultry viscera, rice, fermented or cooked mixed feed (composed of wheat bran, corn meal, Fish Meal, bone meal, etc.). The ratio of animal and vegetable feed should be between 4:6-5:5. The daily feeding amount is 4% to 5% of the overall weight of the turtle, which is fed at 8 o'clock in the morning and at 5 o'clock in the afternoon. In addition can also be fed chopped melon peel, leaves and so on.
