Using new technology to raise fattening shrimp
Xu Zhihua, a shrimp farmer in Fengma Yi Village, Hengli Town, Nansha District, Guangzhou City, contracted 60 mu of pond to raise Penaeus vannamei. In 2007, under the guidance of agricultural technicians, he used enzyme technology and fish and shrimp fertilizer, and achieved a net income of 5000 yuan per mu. Xu Zhihua carried out comparative experiments in two ponds. The No. 1 pond was sprinkled with enzyme bacteria, fertilized and watered with fish and shrimp, and 50,000 shrimp fry were released per mu. He applied sparingly, without using water purifying agents and fungicides throughout the process, but there was no phenomenon of floating head and dead shrimp, and the survival rate of shrimp was more than 95%. 4

How to prevent and control diseases of pollution-free fish
Animal and plant symbiosis aquatic plants and fish symbiosis in the same pond, fish rarely get sick. The aquatic plants planted in the fish pond are rice or lotus root, which are in the east-west direction, with a wide row spacing (more than 33 cm), accounting for no more than 50% of the total area of the water body, so that the lighting effect is good, and the water depth depends on the water tolerance of aquatic plants. Rice is generally less than 30 cm, and lotus root can reach more than 50 cm. Farmed fish can be conventional, famous and special new species. Breeding methods can be used for seedling cultivation and adult fish culture. Because the residual bait and fish droppings are deposited at the bottom of the pond, they are fermented and rotten.
