Yellow croaker culture technology: set up perfect water intake and drainage facilities, the water quality should also meet the standard of aquaculture water, the transparency should be above 35 cm, and equipped with an aerator; Disinfect the pond, test the water before stocking, and apply sufficient base fertilizer; Select high-quality fry and stock them when the water temperature is stable at around 10℃.
breeding method
(1) The water should reach a depth of more than 2m, and the pond should have a stable, sufficient and pollution-free natural water source and a perfect water intake and drainage system. The sandy soil at the bottom of the pond is good, the bottom is flat, and the silt is controlled at about 10cm. The water quality should also meet the standards of aquaculture water, and the transparency should be above 35cm. The water body should have running water all the year round. It is suggested to install an aerator to increase the oxygen content in water.
(2) Both old and new ponds should be disinfected. After 7- 10 days of disinfection and exposure in the pond, about 80cm of culture water should be injected. After testing the water with small fish, the water should be added to more than 2m, and the yellow croaker is ready to be stocked. Before stocking fish, apply sufficient base fertilizer at one time to cultivate plankton according to the situation in the pond.
(3) Select high-quality fry. Generally, the stocking time is in late April, and the temperature is different in different regions. As long as the temperature conditions permit (the water temperature is stable at around 10℃), fry can be released.
(4) Pseudosciaena crocea is an omnivorous fish, which requires high protein content and feed quality. It is required that the content of protein in feed is 35%-45% and the content of crude fat is 5%-8%. Then feed the feed reasonably and scientifically according to the weather, water quality and water temperature.
(5) The disease resistance of Pseudosciaena crocea is relatively strong, and prevention is the main thing in the culture process. Water can be disinfected regularly, drug bait can be fed regularly to prevent diseases, and antibiotics can also be fed in moderation. If the disease occurs, the right medicine can be given in time, and the green fish medicine with high efficiency and low toxicity should be selected for treatment.
