Fall Management Techniques for Fish Species

The suitable temperature for autumn is the peak season for the growth of fingerlings. Autumn fish species management should grasp the following work.
1. Timely ponds After 2 to 3 months of cultivation of fish ponds, water quality tends to age, natural foods decrease, and harmful substances such as hydrogen sulfide and pathogens increase. After entering the autumn, the fish should be transferred to ponds that have been sterilized in the clear pond to purify the culture environment.
2. Scientific feeding is suitable for the autumn climate. Fish species have large food intake and rapid growth. The supply of food must be guaranteed. In the case of herbivorous fish species, the pool of fingerlings containing squid and squid should be mainly fed with green bait, and the concentrate should be properly fed. Every day, ten thousand grass carp species are fed with duckweed and tender grasses ranging from 70 to 90 kilograms and concentrate feed 1.5 to 2.5 kilograms. For polyculture of pupa and carp ponds, fertilization is required once every 10 to 15 days, and 70 to 90 kg of fermented human and animal manure is applied per mu, so that the transparency of the pool water is maintained at 30 to 35 cm. In order to use grass carp as the main species for carp and carp species, fertilization should be given priority, and feeding should be supplemented. In addition to Shiji Fei, apply topdressing once every 5 to 10 days, and treat 80 to 100 kg of manure per mu. 20,000 fish per day, two to four kilograms of bait, and 50 to 70 kilograms of green bait.
3. Divided and managed fish species should be properly reared according to different specifications, so that the specifications of the fish species put in the same pool are the same. Fish species above 16 cm can be placed in adult fish ponds, and small fish species need special pools to avoid competition.
4. During regular patrol fish species cultivation, it is necessary to maintain a daily patrol pool, observe the fish’s feeding and living conditions, pay attention to changes in water quality, change new water frequently, and add new water once a week. And often clean the food market, remove the residue leftover bait in time, every half a month in the food market with 0.5 kg of bleached water sprinkling, regular feeding baits, 2 times a month, each time for 3 days. Found sick fish, dead fish to remove in a timely manner.
