After one year of use, the fish ponds have deposited a lot of food residues, fish excrement and other garbage, forming a layer of pond mud at the bottom of the pond. These pond muds not only affect the depth of the fish ponds, but also contain a large amount of humus in the pond mud. They are easily decomposed in hot weather and consume a large amount of dissolved oxygen, leading to deterioration of water quality. In addition, these ponds may contain a large number of pathogenic bacteria or parasites, which seriously affect the healthy growth of farmed fish in the second year. Therefore, the comprehensive clean-up of silt in fish ponds in winter and the reinforcement of fish pond ponds are extremely beneficial to the second year of fish farming.
The method of trimming fish ponds is to first catch and fish low-temperature-resistant fish (such as freshwater whitefish, tilapia, etc.) before the first cold air in the winter, and it is not enough for the listed fishery pond, but it must be Take insulation measures. In the future, according to the actual quantity of food fish in the fishpond and the supply and demand situation in the local market, they will try to get listed in batches before the Spring Festival, and finally completely dry the pond. After 2 days to 3 days after the dry pond, until the surface layer mud has evaporated some of the water, the mud can be cleared. Cleared pond mud is piled on the pond base and used as a base fertilizer for growing plant feed. If there is too much mud in the surface pond, it can be laid on the ground and dried as a fertilizer. After clearing the surface pond mud, we must also level the bottom of the pond, raise and reinforce the pond foundation, and maintain auxiliary facilities such as aqueducts, waterways, and bait-feeding racks. After the fish ponds are finished, do not put water immediately and allow the bottom of the pond to be exposed for more than half a month to kill some pathogens and parasites. In the 20 days to 30 days prior to the release of fish, fishponds should be used to disinfect fish ponds. After the toxicity disappears and the reinforced pond-base embankments are solid, new water can be added for reuse according to production needs.
