This standard applies to the pond breeding of green carp in Bayannur region; Main technical content: Basic environment 3.1 Pond requirements Pond area: 5 mu to 10 mu. Pond shape: East-west orientation, rectangular, with a length-width ratio of 3:2 or 2:1. Pond depth: 2.5 m to 3 m. Bottom quality: The pond bottom should be flat, with a slight slope to one corner, and the sediment thickness should not exceed 15 cm, with minimal leakage. 3.2 Water source The water source should have sufficient water volume and no pollution sources that threaten fishery water quality. The water quality of the water source should comply with GB 11607. 3.3 Water quality The water quality of the breeding pond should comply with NY 5051. 3.4 Other requirements a) Each pond is equipped with one aerator, with a power of 0.3 kW/mu to 0.5 kW/mu. b) The water inlet and outlet should be convenient and independent. 4 Breeding techniques 4.1 Preparation work T/TFHT Y022—2020 24.1.1 Pond preparation and cleaning a) Repair the pond banks and level the pond bottom, removing weeds and excess sediment. b) Clean the pond with lime. 10-15 days before fish stocking, the pond is filled with 5 cm to 10 cm of water, and 60 kg/mu to 75 kg/mu of lime is added, dissolved in water, and sprayed throughout the pond. The next day, the pond is raked once. If the pond is cleaned with water, the water depth should be 1 m, and the lime dosage should be 125 kg/mu to 150 kg/mu. c) For ponds with high pH values, bleaching powder (effective chlorine 30%) is suitable for pond cleaning. When the water depth is 5 cm to 10 cm, the dosage of bleaching powder is 2 kg/mu to 3 kg/mu. For ponds cleaned with water, the concentration of bleaching powder reaches 20 mg/kg. 24.1.2 Application of
