Guangdong wolfberry (commonly known as Xijiang list, big eye list, flower list) is tender, delicious, and is well-known both at home and abroad. The Xijiang River, located in Luobian Town, Yunan County, is the largest natural spawning ground in Guangdong. Since 1992, the Yunan County government has invested a lot of manpower, material resources, and financial resources to establish a fishing ban on the natural spawning grounds. Banned fishing period, so that this excellent aquatic resources have been effectively protected and proliferated. In addition, the Yunan County Fisheries Department has been carrying out experimental research on the artificial propagation and pond culture of the pupa in Guangdong for many years and has achieved certain results. The current technology of aquaculture ponds in Guangdong is briefly introduced and is for reference only by farmers.
Life habits and food habits
According to observations and studies, Guangdong quail lives in the middle and lower layers of water bodies and is omnivorous. Adult fish mainly ingest mollusks such as river otters and eat higher aquatic plants. Artificial feeding can feed a small amount of carp feed, pig blood, chilled fish, peanut bran, etc. When feeding artificial compound feed, the crude protein content of the feed is required to be more than 40%. Radon is a wide temperature fish in Guangdong, and its optimal growth temperature is 18-25 °C.
Adult fish culture
1. Polyculture of ponds Polygonum polyfasciatus is reared in ponds of four large populations of fish. Each group has about 100 centimeters of seedlings with a length of more than 10 centimeters. The first anniversary of breeding is that without raising any feed, the body weight can reach 400. -500 grams, if mixed in a large feeding pond or duck pond, its growth is better.
2. Pure pond cultivation The pond area of ​​pure Guangdong pond is generally 5-10 mu. The water depth is 1.8-2.5 meters. The bottom of the pond is flat, drainage and irrigation are convenient, the water source is sufficient, the water quality is good, and there is no pollution. Prior to planting, clear ponds should be disinfected according to the routine clear pond method. Use 3% - 4% saline or potassium permanganate solution (100 pounds of water with 1 g of potassium permanganate) to disinfect the fish for 5-15 minutes when the seeds are released (Specific dipping time depends on the tolerance of the fish. And set) to remove the bacteria on the fish. It is recommended that the stocking density of the purebred Guangdong cockroach be better than 800-1000 fish species with a length of more than 10 cm per acre, another 30 aquaculture species with a large stock size per mu, and 10-20 fish aquaculture species to improve water quality. . After stocking fish, we must strengthen feeding and management, feed and feed to achieve "four set" (that is, timing, quantitative, qualitative, positioning), feed quality to ensure fresh, palatable, feed generally 3% of fish's body weight - 5%, at the same time according to the changes in the weather and the flexibility of the fish to eat. During the breeding process, according to many years of experiments, it was considered that Guangdong quail was mixed and fed under the weight of 50 grams before the next time. After 50 grams, high-energy artificial compound feed was better.
Fish Disease Prevention
At present, no serious diseases have been found in the breeding process, but general diseases may still occur, such as hydromycosis, cat head lice disease, and bacterial skin rot disease. If cat head lice are found, 0.5 ppm of chlorfenapyr (50 grams per metre of water per acre) can be used to spill the entire pool, and the disease can be treated thoroughly every 3 days. If bacterial battling disease is found, 1 metre of water per mu shall be fused with 20 kg of lime into lime milk. Quanchiposa or splashing agent (500 ml per mu for 1 meter water depth) shall be splashed on the ground. The fish should be fed again the next day. Bacteria or strong grams of fish medicine. Even feed for 3-5 days. In short, we must strengthen water quality management in peacetime, pay attention to timely water changes and oxygenation, regular water disinfection and feeding of drugs, to prevent the main prevention and control combination, so as to effectively prevent the occurrence of fish disease, so that Guangdong health Grow. In particular, it is pointed out that Guangdong cockroaches are very sensitive to copper sulfate, and a very low concentration of copper sulfate can cause fish death, so it should be used with caution.
