The suitable water temperature in autumn is the peak season for fish growth. In the autumn, the management of fish species should focus on five tasks: clear ponds, sub-cultivation, sparse breeding, feeding, and patrol pools.
1. The ponds in Qingtang pond are cultivated after 2-3 months of fish species, the water quality is aging, the natural food is reduced, and the harmful substances such as hydrogen sulfide and pathogenic bacteria are increased. After the autumn, the fish species should be transferred to ponds that have been sterilized through clear ponds for cultivation. .
2. Dividing the fingerlings in different sizes according to different specifications, so that the specifications of the fingerlings in the same pool are the same. Generally, more than 16 cm of fingerlings can be put into adult fish ponds, while small fingerlings need special pond cultivation.
3. It is an important part of increasing the survival rate of wintering fish species that large-sized fingerlings are bred in the rare autumn season. Should be based on the size of the water, water depth and other conditions, reasonable dilute, promote the growth of fingerlings. 1.5 meters deep ponds, put 7-8 centimeters per mu of water species 4000-6000 tail. At the end of the year, the length of the fish species can reach 13-17 cm.
4, feeding the autumn fish species large food intake, rapid growth, must ensure the supply of food. The food is dominated by herbivorous fish species, and the fish species pool should be mainly fed with green bait, and the appropriate feed should be properly fed. First throw the green bait, then cast the refined bait.
5. During the cultivation of patrol fish ponds, it is necessary to insist on daily patrol pools to 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.
