Culture method of sea bass (how to catch sea bass)

1. Culture method: Bass is specially cultured in ponds and cages, and the stocking density in ponds is 800- 1000 fish per mu. In order to improve the water quality and make full use of the residual bait, 40 bighead carp with the specification of 250g and 50g crucian carp 100 can be interplanted per mu, which is the best before the fry go into the pond. There are 25 fish per square meter in cage culture, and 30-40 fish can be put per square meter where there is running water.

2. Feeding method and feeding amount: the feeding amount depends on the growth of fish, water quality, weather and feed quality.

3. The fry just entering the pond should be mixed with miscellaneous fish with meaty bones, ground into pulp with a meat grinder, boneless, and then a small amount of eel feed is added to make a mixed feed, which is fed three times a day, and the feeding amount is 50% of the weight of the fish species, and then gradually reduced to 20%. In the first three days of feeding, it is best to add 5 grams of Lidaling and 4 grams of oxytetracycline to every 50 kilograms of feed for disease prevention.

4. After10 days, the fish grow up gradually, and the feeding should be "four fixed". When taming, the board should be dismantled before feeding, and the feeding should be slow first and then fast, with fewer times, and the feed should be evenly thrown within a certain water surface range, so that the feed will be swallowed by the fish when it floats on the water surface.

5. When the fry grows to about 15cm, it can be cut into palatable pieces and fed with chilled fish, which generally accounts for 12% of the fish weight, and then gradually decreases to 8%- 10%. Feeding high-energy puffed feed, the feeding amount should be controlled at 8%- 10% of the fish weight, and the feeding amount should be adjusted every 8- 10 days. In a word, we should not feed spoiled feed, anoxic fish, fish in rainy days, fish that don't grab food, and fish that grow fast until it goes on the market.

6. Feeding management: The water quality of perch is fresh, the dissolved oxygen content is high, and the transparency is above 30cm. So change the water frequently, especially in all seasons. Disinfect with quicklime for 2-3 times during the whole breeding period, maintain slight alkalinity while improving water quality, and insist on patrolling the pond in the morning and evening. In cage culture, cages should be inspected and cleaned frequently to prevent hypoxia caused by net clothing blockage.
