Fish bone culture

It is a subfamily of the genus Oystercatcher, Acipenseridae, and Moorishinae, commonly known as fishbone fish bone and chicken shrimp. It has a long body, a thick front end, a flat rear section, medium to large heads, large eyes, prolonged kissing ends, brownish or yellowish body color, many small black spots on the body, and 7 to 14 dark spots on the sidelines. The rivers, lakes and reservoirs distributed in the Yangtze River Basin inhabit in the middle and lower layers of water bodies, and the largest individual can reach 2 kg. It is a medium and small-sized fish with high economic value. The fish has the advantages of beautiful body shape, miscellaneous eating habits, strong adaptability, tender meat, delicious taste, and a pretty market. 1. The pond requires an area of ​​about 5330 square meters, with a water depth of 2 to 2.5 meters. It requires sufficient water, good water quality, and easy access to water and drainage. 15 days before stocking, 200kg to 250kg of quicklime per 667m2 of water will be disinfected with clear ponds. About 400kg of organic fertilizer will be applied after 4 days of disinfection, and 20kg of ammonium bicarbonate and 30kg of superphosphate will be used to cultivate food organisms. 2. The fish stocking selection is free from disease, disease-free, and the body is robust, and the neat fish bone fish of the next year are stocked and stocked on sunny days in early spring. Each 667m2 enlarged fish bone fish species from 1200 to 1500 tails, and with tail weight 50 grams of squid 120, 300 grams of scorpion 80 to 100 and a small amount of small-scale carnivorous fish, avoid Raise fish, such as squid, squid and grass carp, that compete for food so as not to compete with fish and fish. When fish stocks are stocked, they are soaked with 3% to 4% saline for about 5 minutes. 3. Feed feed is mainly fed with artificial compound feed, supplemented by fertilization and culture of plankton. The feed formulation is: 30% bean cake, 40% cake, 15% sesame cake or peanut cake, 5% fishmeal, 10% flour, mix the above raw materials, add appropriate amount of water and mix into dough or soft pellet feed. On the bait station. The bait station can be made of 5 meters long, 3 meters wide, dense mesh cloth, with bamboo poles or stakes fixed in the middle of the pond, the depth of the net cloth from the water is 0.8 meters to 1.2 meters, depending on the size of the pond, the general 2600 square meters set a food table. Feeding 2 times a day, time is at 10 o'clock in the morning and 5 o'clock in the afternoon respectively, when the water temperature 15 °C ~ 20 °C, the daily feeding amount is 1% of the fish body weight, 20 °C ~ 25 °C is 1.5%, above 25 °C 2%. While feeding the feed, it is also necessary to pay attention to fertilization in order to keep the plankton in the pond water prosperous. When the water begins to fade, apply organic manure 50kg to 80kg, ammonium bicarbonate 4kg, superphosphate 2kg per 667m2, and maintain a water clarity of 30cm to 40cm. In the breeding process, round catches can be carried out to keep the reasonable density of the fish at all times. Fish and fish bones grow rapidly from fry to sexual maturity (body weight 250g to 300g), so the weight of each fish caught can be set at about 250g to increase aquaculture production and economic efficiency. 4. Routine management insists on daily inspection of the ponds, observes water quality and fish activity, finds problems in time, and adjusts the pH value of the pool water to between 7.2 and 8.2. Lime can be applied two or three times per month. The amount of water applied per cubic meter of water is 15 Grams ~ 20 grams, the whole pool of water evenly spilled; often add new water, deepen the pool water to the highest water level in the hot season, in order to maintain good water quality, increase water dissolved oxygen, prevent flooding dead fish; rational use of aerator, in addition to Fish floating head should be turned on in time, but also must be sunny at noon to start 1 hour to 2 hours, accelerate the upper and lower aquifer convection.
