This technology is expected to demonstrate an area of ​​400,000 mu in the province. The main cultured species are grass carp, squid, stingray, catfish, catfish, etc. The total output is 280,000 tons, the total output value is 2.2 billion yuan, and the new profit is 200 million yuan. Suitable for promotion in the province's refined fish ponds. HEBEI PINGLE FLOUR MACHINERY GROUP CO., LTD , https://www.plrollermill.com
Technical points:
1. It is required that the production of main cultured fish accounts for 80%, and that of stocked fish accounts for 20%.
2, the main cultured fish are: grass carp, herring, catfish, squid, head bream, yellow croaker, etc.; breeding fish are: bream, squid, large oysters, scales, etc.
3, feeding technology: set up a bait station, domesticated main breeds to form a feeding habit. Feeding adhere to the "four set." The daily feeding amount is determined according to the season, the quality of the water, the type of fish, the amount of ponds, food intake, and activities.
4, feeding and management. Equip and use aerators. Discharge the old water in the pond regularly and add fresh water. From June to September every year, use quicklime or probiotics to regulate and improve water quality. The disease is mainly prevention, insisting on prevention and treatment. Sooner or later, each patrol pond will be well-recorded. (Deng Renxiang, expert of Provincial Aquatic Technology Promotion Center
