Pond farming is a fish farming method used in most areas of China. The current output accounts for more than 60% of freshwater fish farming. It has the characteristics of small investment, large returns, quick results, and stable production. Today, I will talk to you about the method of raising fish in freshwater ponds. Freshwater pond fish farming: fish pond conditions

Water quality: Abundant water sources and good water quality are the basic conditions for fish farming.
Bottom quality requirements: The best bottom quality of the pond is loam, sandy loam, and then clay.
Area: Generally, the area of a fish pond is 5-10 acres, which is easy to manage. The brood stock ponds, fry ponds, and fingerling ponds are suitable for 3-5 acres.
Water depth: Generally, the water depth of the fish pond is 2~3 meters. The wintering pool is preferably 1.5-2 meters below the thickest ice layer in severe cold. The water depth of the fry pond and hatching pond is preferably 1.0_1.5 meters. Fish seed ponds generally require a water depth of 1.5-2.0 meters.
Freshwater pond fish farming: preparations Rest the pond, remove weeds and impurities at the bottom of the pond, and level the pond.

Rest the pond, remove weeds and impurities at the bottom of the pond, and level the pond.
A. Clear pond disinfection
Soil method to clear the pond: that is, draining the water in winter, removing the predators and improving the bottom quality through freezing, drying and exploding the sun at the bottom of the pond.
Drug clearing pond: Can use quicklime or bleaching powder.
B. Water injection and cultivation water quality
After the pond is disinfected, after the drug toxicity disappears, you can live in the new water. 7-10 days before the fish stocking, put in the base fertilizer and cultivate the water quality.
Freshwater pond fish farming: fingerling stocking
In fish farming, stocking large-scale fish species is a high-yield measure for pond fish farming. Large-sized fish species have the characteristics of strong disease resistance, high survival rate and rapid growth. Under pond breeding conditions, grass carp generally stocks fingerlings weighing 0.25 kg. After 4 months of rearing, it can reach a size of 0.5_0.75 kg in autumn. If stocking 0.5_0.75 kg, it can grow to 1.0_1.5 kg. Silver carp and bighead carp are generally put in first-year-old fingerlings, 12-18 cm in size, and can reach 0.5-0.75 kg in the pond. Other fish such as carp, crucian carp and bream are stocked with first-year-old fingerlings, with a sparse density, and the size is about 12-14 cm. After several months of rearing, the carp can reach the size of 0.5 kg and the bream 150-350 grams. More than 100 grams of crucian carp.
