The winter leisure season of the fishery is a crucial period for the construction of new fish ponds or the reconstruction of old fish ponds. For the fish ponds that have just been excavated, pond construction and technical treatment are required. The old fish ponds have been cultivated for one year or many years. During the breeding process, fertilizers and bait residues, fish manure, and sediment impurities have accumulated over time. If they are not updated in time, they will affect the next year’s aquaculture production and the improvement of benefits. Today, Xiaobian talks about the technical measures for standardization construction and renovation of fish ponds.

1. The selection of breeding sites must be constructed in accordance with the requirements of fishery farming.

1. The location of the fish pond should be scientific and reasonable, and choose a place where the water source is stable and not easily polluted by pollution sources.

2. The soil of the pond is suitable for loam. The shape of the pond is rectangular. The ratio of length to width is generally 2-4:1, and the width of one side is preferably not more than 50m. It is not appropriate to have tall trees and buildings around the pond. Shading, wind blocking and obstructing farming operations.

3. Fish ponds must adopt dredging measures every year to improve the quality of the sediment and prevent deterioration of water quality.

4. Each fish pond should have separate injection and drainage channels, and build anti-escape facilities to escape fish.

2. The planning and design of fish pond construction should be reasonably determined according to the cultured species and breeding model.

1. The construction and reconstruction of fish ponds should be based on the varieties and breeding models that need to be cultured in the current year to determine the planning and design of the reconstruction.

2, breeding adult fish: the pond area is about 10 acres of ponds is appropriate, the water depth is more than 3m, the fish pond is mainly rectangular, the ratio of length to width is 5:3, the ratio of the area of ​​the fish pond and the fish pond is 8:2 or 9:1.

3. High-yield fish ponds: The bottom of the pool is not water-permeable, has a water source that meets the fishery water standards, a complete irrigation and drainage system and an effective aeration facility, and has a certain area to grow feed crops.

4. Farming fry: The pond area can be slightly smaller, the requirements are complete, and the fish pond reconstruction construction should be changed according to the cultured species.

Third, fish pond culture conditions must be maintained according to the needs of breeding and improved year by year

1. After the fish are all started at the end of the year, all the pond water will be drained in time, the silt will be removed, and the piled silt will be transported to the farmland and vegetable fields for fertilizer.

2, through the removal of silt, repairing ponds, etc., can effectively expand the capacity of fish ponds, enhance the ability to resist drought and water.
