The genus Erythroceroses is a member of the genus Amaranthidae, Amaranthidae, Red-eyed Oystercatcher, commonly known as red-eye fish, and red-eyed fish.
Senate fish is one of the main high-quality economic fish in the river. The meat is delicate, delicious and nutritious, and it is favored by consumers. The fish has the advantages of rapid growth, strong adaptability, miscellaneous feeding habits, low breeding cost, high selling price of the commercial fish, and body shape resembling that of the first-year grass carp, and is currently a popular variety for freshwater aquaculture.
I. Pond conditions Aquaculture ponds require adequate water sources, good water quality, no pollution sources nearby, good water retention performance, convenient drainage and drainage, flat bottom, and less silt, with an area of ​​1000-3000 square meters, water depth 1.2-2.0 Meter. The pool water requires “fat, live, tender and coolâ€, and the transparency of the pool water is maintained at about 25-40 cm.
Second, the pond disinfection Influent ponds should remove too much silt, winter dry pool exposure, per square meter calcined slurry with 100 to 150 kilograms, disinfection 10 to 15 days after 667 square meters can be released by fermented decomposed manure 200 ~ 300 kg of basal fertilizer, and then filtered into water with a 60-mesh sieve. Third, the fish species were selected to maintain healthy and lively quality seed. The fish can be soaked with 3% to 5% of salt water for 5 to 10 minutes before releasing. The main pond for raising fish is generally 800 to 1200 fish per 667 m2, and 100 to 200 fish for every 667 m2 of mixed ponds.
Fourth, feeding and management
1. The feed was fed to the red-eyed oysters, and algae, organic crumbs, and dried grasses were all available for feeding and artificial diets were preferred. In the main ponds, full-price pelleted feeds are used. The content of crude protein in feeds is approximately 30%, and fine green algae and soft, fresh, palatable waterweeds, ryegrass, and vegetable leaves can also be used as auxiliary feed. .
The daily feed is 3% to 8% of the fish's body weight. In general, every afternoon. Feeding feeds should adhere to the principle of "Four Ding" feeding, but also determine the reasonable amount of feed according to the weather, water temperature, water quality, and the fish's eating and feeding conditions. From June to July and from September to October, the food intake was more vigorous, and in the midsummer, ammonia nitrogen was within 1 mg/L and nitrite was within 0.06 mg/L. In the middle and later stages of breeding (especially in the hot season), new water should be replaced in time to keep the water quality of the pond fresh, and the transparency should be controlled within 25-40 cm. 10 to 15 days, every 667 square meters of lime with 10 to 15 kg Quanchiposa once, so that the water was slightly alkaline, in order to facilitate the growth of fish and the prevention of fish diseases. Conditional households can use EM fluids, photosynthetic bacteria and other microbial preparations every 12 to 15 days depending on pond water quality, water temperature, etc., which can effectively improve water quality.
2. Day-to-day management During the aquaculture process, daily observation and diligent inspection of ponds must be observed, water quality changes should be observed, fish activities, feeding conditions, and disease-free conditions should be observed. Frequent removal of rubbish around fish ponds, residual baits on food stations (fields), floating objects on water surfaces, etc.
Fifth, fish disease prevention and control of red-eye turtles have strong adaptability to life. The infection rate of various diseases and the mortality rate after infection are low, but the prevention and treatment of fish diseases should adhere to the principles of “disease-free prevention, early disease prevention, comprehensive prevention, and active treatmentâ€. In addition to disinfecting the fish when the species is under the pond, it is also necessary to disinfect the fresh grass (food), food facilities, tools, etc., and to regularly use fishery medicine for the prevention of fish diseases during the summer and autumn fish disease epidemic season.
Sixth, the harvest of adult fish When the majority of individuals to reach the market specifications, should catch large stay small, timely listing.
