Cage culture jaundice technology

First, the breeding conditions The surrounding environment of the pond is good, no noise, no pollution, less silt, water depth of about 1.5 meters, drainage and irrigation convenience.

Second, cages generally choose high-quality polyethylene, the size of 2 meters 3 meters 1.5 meters is appropriate. The water depth is 60-80 cm, and the water height is not less than 60 cm. The cages are filled with water peanuts as a carrier to purify the water and allow them to inhabit. The area of ​​cages should not exceed 1/3 of the pond. Ponds can be stocked with turtles and storks.

Third, the selection of seedlings generally choose body color golden or yellow, slender body shape, such seedlings adaptability, feeding ability, fast growth. The body shape is short and thick, body color gray, black and green seedlings have weak feeding power and slow growth speed.

Fourth, seedlings of different specifications of the fish should be placed in different cages to prevent mutualism. Stocking should be selected from 9 to 10 o'clock in the sunny morning. The water temperature should not be lower than 22 degrees Celsius, and about 750 grams per square meter should be stocked.

5. Feeding and Feeding Bastards The bait began to feed after 3 days and started to feed mainly fish gills. Two feeding points for each cage were used. The food was fed at 2% of the weight of Astragalus membranaceus. One week later, it was transferred to each cage. 1 point, and increase the amount of feeding. When the food intake of Scutellaria baicalensis reaches 3% to 4% of its own body weight, it starts to feed pelleted food. After stocking for 10 to 15 days, the ratio of pellet feed to surimi gradually reached 1:1.5, which should be gradual.

6. The water quality management observes the water quality on time every day. The water color is suitable for light green. Fermented cake fertilizer or green manure was used to cultivate abundant plankton. In the rainy and continuous weather, it is necessary to use degraded elements in a timely manner to promote the conversion and decomposition of harmful substances such as ammonia nitrogen. Pay attention to observe changes in water volume and timely irrigation and drainage of pond water.

Seven, disease prevention and treatment of jaundice disease focuses on prevention, we must often take oral anti-stress agents antibacterial agents, such as stress Ning, ginseng Immunity, fluorotonic test, etc., enhance immunity. In addition to the prevention and control of blisters, water blemishes and jaundice on the body surface, will draw blood, cause skin damage, affect the quality of production.
