The red eyed owl is a member of the order Oystercatcher, Acipenseridae, Yaloodinae, and Erythroceros, commonly known as "red-eye." It is a rare wild economic fish in the Yangtze River. The meat is tender and delicious.
First, biological characteristics
1. Shape characteristics: Red-eyed squid is spindle-shaped, grass-like fish like shape, rear flat, tapered head. The body is silver-white with a dark gray back. There are two pairs of whiskers on the kiss end. There is a dark spot at the base of the scales on the side of the body, forming a tandem stripe. The scales on the lateral line are obvious, the scales are larger, the lateral line is straight, and the posterior peduncle extends to the center. Caudal fins are deep forked, with an obvious erythema above the eye margin, commonly known as "red eye."
2. Habits: Red-Eyed Catfish is responsive and good at jumping. It is easy to jump and collide when the net is pulled and transport operations are frightened. Naturally distributed in slow-flowing waters of rivers, lakes and rivers, it is a medium-sized fish. It has a wide temperature range and can naturally overwinter in most areas of China. After artificial domestication, it is suitable for breeding in ponds, rivers, lakes, reservoirs and other water bodies.
3. Feeding habits: The red-eyed owl is an omnivorous fish that feeds on small aquatic plants, algae, organic debris, aquatic weeds, and benthic animals in the natural environment. After domestication, it also feeds on compound feed.
4. Growth: Slower growth in the natural environment. However, after domestication and domestication of compound feed, the growth rate was accelerated. The fish species can be up to 20~35g/tail in the year, and the product fish size can reach 400~500g/tail, and the large can reach 750g/tail.
Second, adult fish breeding
1. Production environment and fishpond conditions Pollution-free T. erythema production base should be built in areas without industrial "three wastes", no agricultural, medical waste, no urban waste and domestic sewage pollution, quiet environment, convenient transportation, and air quality in line with "GB 3095 -1996 Standard. The requirements for adequate water, fresh, rich dissolved oxygen, pH 7 ~ 8.5, water quality in line with "GB 11607-1989 fishery water quality standards" and "pollution of freshwater aquaculture water quality" requirements. Ponds are preferably rectangular in the east-west direction. The area of ​​a single pond is 0.2-0.6 square hectares. The depth of water is about 2m. The soil quality conforms to the “GB 15618-1995 standardâ€. The bottom quality is clay, and the loam is next. The silt is about 10cm thick at the bottom of the pool, with 0.3-0.5kW aerators per 667m2 of water surface. The fish pond is equipped with an intake and drainage system, and is equipped with a water pump and other water exchange equipment.
2. About 10 days before the pond disinfected stocking fish species, 75 to 100 kg of fresh lime dry ponds were disinfected per 667 square meters of water to kill the wild fish and pathogens, and to improve the bottom quality and water quality.
3. In the first 5 days after the cultivation of water quality fish species, about 200 kg of fermented organic fertilizer is applied to 667 square meters of water, so that the water is yellow-green, and the transparency is maintained at 30-35 cm.
4. The fish stocking selection is to be stocked in winter and spring seasons, and the water temperature should be 5~10°C. At this time, the fish's activity is weak, and the scales are close to the fish, so it is not easy to fall off. Before stocking, the fingerlings were bathed with 3% to 5% saline for 5 to 10 minutes. The main pond is raised, and 700 to 900 tails of red-eyed salmon are stocked on a surface of 667 square meters of water, and then are paired with 100 to 150 tailed white mullet species. The pond is nested, and each 667 square meters of water can be nested with 100 to 200 red-eye fish species. The fish species are required to be strong, disease-free, uniform, and large in size.
5. The crude protein content of artificial feed formulated for feeds of red-eye bream should be about 28%, and the feed coefficient should be around 1.8. It is required that the raw materials of the compound feed comply with the regulations, and must not use moisture, mold, insects, spoilage, oil, pesticides, etc. Contaminated raw materials such as harmful metals. Such as the purchase of commodity feed, should meet the "GB 13078-1991 feed hygiene standards" and "NY 5072-2002 pollution-free food with fish feed safety limit." Feeding should follow the scientific "four-seeing" and "four-determined" principles and have a good grasp of each feeding amount. In the main growing season, they are fed once a day in the morning and in the afternoon, and it is usually appropriate to eat about 20-30 minutes after each shot. In addition, according to the feeding habit of the red-eyed oystercatcher, some green feeds, such as duckweed and other grasses and grasses, should also be fed to promote growth, reduce feed costs, and increase economic efficiency.
6. Day-to-day management In the main growing season, stick to the morning and evening patrols, observe the fish's activities, food intake, and water quality, and make records of the Tangkou. In the hot season, it is necessary to pay attention to timely changing of water, generally about 10 days plus a water change once, in order to maintain a clean water quality and higher dissolved oxygen. In the growing season, 1 to 3 pm every day, the aerator is turned on. Once the floating head is found, the aerator must be turned on in time. Every 20 days or so, every cubic metre of water is melted with 20 grams of quicklime and splashed in the whole pool to regulate water quality. In natural conditions, the resistance to disease is strong, but when it comes to artificial feeding, attention must be paid to preventing disease, and the principle of “prevention as the main, active prevention and control†should be adhered to. Redeye salmon disease is similar to regular fish. The medication should comply with the "NY 5071-2002 Guidelines for the Use of Non-Hazardous Food Fish Drugs," and do not use drugs that are prohibited by the State. Prevention of bacterial diseases can be carried out every month (May-September) with a disinfectant Quanchiposa. Paraquat can be sprayed with avicelid Quanchipate. If there is an anchor head, it should be separated every 5 to 7 days before spilling. . Before the adult is listed on the market, it is necessary to abide by the corresponding withdrawal period to stop the use of drugs to protect the quality of the listed fish.
