Fish stocks for grass carp and group head bream should account for 40-50% of the total stocking amount, carp accounts for 20-30%, carp and carp accounts for 20-30%, carp and carp accounts for 10%, and fish species specifications 100-200 g/tail. In winter, when they are stocked, they usually start after the adult fish are caught and can adapt the fish species to the living environment of the reservoir as soon as possible. In the spring, when the fish is stocked, it is usually carried out after the spring, and the reservoir can use the free time for dry storage, disinfection, and deforestation. The amount of fish released per hectare of water is 3000-3750 kg.
Feeding technology Reservoir fish farming can be fed only with compound feed or fed with compound feed and green feed. The daily feeding amount should be constantly adjusted according to the changes in water temperature and the weight gain of the fish. The compound feed can be calculated according to the daily bait rate table for cage fish farming and fed regularly at a fixed point; the amount of green feed fed is 1.5-3.0% of the total weight of herbivorous fish, and should be placed in the feed box. The compound feed is generally fed twice a day, 8-9 am and 2-3 pm; green feed is fed once a day in the afternoon.
Production management should disinfect and remove reservoirs before the release of fish species, increase the survival rate of fish species, and frequently check fish escape prevention facilities. Small reservoirs of fish are also often confronted with conflicts with irrigation water. In the drought year, the water for the reservoir should be “tried”, ie, the irrigated area, the minimum water level for the fish culture, and the time for pumping water. In special circumstances, it is necessary to move Kugan fish, water to fish, and ensure that production and fish farming are correct.
