The rational allocation of broodstock stocking density can not only make full use of the water body, but also make the gonad develop well. Stocking broodstock in winter generally requires the selection of ponds with sufficient water sources, flat bottoms, sheltered winds, and water insulation, with an area of ​​10-15 acres. The main broodstock broodstock pond can be reared with 5 to 8 kg of broodstock broodstock per acre, 10 to 15 tails, broiled broodstock of the same specifications and 3 to 5 tails, and 3 to 5 tails of broodstock with a tail weight of about 10 kg. The main broodstock broodstock pond can be stocked with 15 to 20 kilograms of broodstock broodstock per acre with 10 to 15 tails, and bred broodstock with a tail weight of about 10 kilograms. The main pond raising grass broodstock, can be stocked with 8 to 10 kg of grass broodstock 15 per acre, with brood broodstock or broodstock bred 3, broodstock head bream broodstock 12 kg, the ratio of male to female is generally 1:1.5, the lowest a lot At 1:1.
Strengthen the management of overwinter broodstock pools with special personnel management, frequent patrol ponds, regularly add new water, increase dissolved oxygen, prevent leakage, maintain a certain water level, and increase water temperature. When the weather is continuous and the water temperature is above 6°C, appropriate amount of fine material and green leaves such as vegetables and leaves should be fed to enhance the physique of the broodstock. For the main ponds for raising puffer fish and squid, some fermented manure should be put in periodically throughout the wintering period to increase the water temperature and improve the water quality.
