Chengyu's feed requirements and feeding methods are basically the same as those of young pigs. In order to ensure proper amount of fresh feed, mud loach, snail, etc. can be propagated in the pool. Generally, after entering the spring, deepen the water level 30-40 centimeters, fertilize and cultivate good water quality, and then put 5-10 kilograms of loach and 50-100 kilograms of snails every 0.07 ha. After spawning and breeding, put into the clams, and gradually Deepen the water level. In this way, it can provide a part of natural feed stably for a long time and stably. In addition, pupa and snails can also be cultured artificially as a source of animal protein for clams.
Chengyu has a large food intake and a large amount of manure, which can easily contaminate water bodies (eutrophication). It is necessary to strengthen the management of water quality. The feed must be deposited on the food table (or pool side slope) and cannot be cast in a random manner. This can remove residual feed in time and reduce the pollution to the water quality. At the same time, add water once every 10 days. In addition, 1.5 kg (slurry water) of lime are spilled every 0.07 ha of the month to regulate water quality and kill germs.
In order to maintain a suitable water temperature, different water levels are adjusted in different seasons. Maintaining 50 to 80 cm in the spring will help increase the water temperature and allow the shrimp to eat as early as possible. In the summer, it will increase the water level and cool down and prevent heatstroke. In the fall, maintaining a high water level and slowing down the water temperature will help maintain warmth during winter.
