How to prevent winter broodstock from falling out

Broodstock breeding is generally divided into four stages: postpartum care, autumn cultivation, winter cultivation and spring cultivation. In the winter cultivation stage, due to low temperature, broodstock activity is reduced, and feeding capacity is weak, fish diseases often occur. If poor management occurs, the production of broodstock will be artificially hatched in the coming year, fish species will be supplied, and adult fish breeding will have a great impact on several production processes. . To prevent broodstock from falling out in winter, we should focus on the following work. Rationally rearing a reasonable stocking density is an important condition for ensuring the success of broodstock breeding. The broodstock stocking density can both fully utilize the water body and make the gonadal well developed. The ponds for raising winter broodstock should generally be well-watered, flat at the bottom of the pond, sheltered from the sun, and a pond that retains water and heat, and an area of ​​10 acres to 15 acres is appropriate. The main broodstock broodstock pond can be stocked with 5 to 8 kg of tail fish per acre, 10 to 15 tails, and broilers with the same specifications of 3 to 5 tail broodstock, tail weighs about 10 kg of grass broodstock 3 to 5 tail. The main broodstock pond can be stocked with 15 to 15 tails of 15 kg to 20 kg per mu, and 3 to 5 tails of broodstock weighing approximately 10 kg in weight. The main grass raising broodstock pond, can be stocked with 8 kg to 10 kg of grass broodstock per acre 15, with oyster or broodstock 3, broodstock bream broodstock 12 kg or so, the ratio of male to female is generally 1:1.5, the lowest Not less than 1:1. Strengthen the daily management of the overwinter broodstock pool requires special management, frequent patrol ponds, regular addition of fresh water, increase dissolved oxygen, prevent leakage, maintain a certain water level, and increase the temperature of the entire water body. When the weather is continuously fine and the water temperature is above 6°C, appropriate amount of fine material and green leaves such as vegetables and leaves must be fed to feed the fish directly to enhance the body quality and reduce the loss of sputum. For the pond where the main carp is raised, some fermented manure should be put in regularly throughout the wintering period to increase the water temperature and fertilize the water quality. In the winter cold season of fish disease prevention and control, broodstock is easy to get watery mildew, white skin and other diseases, attention should be paid to the following matters: When catching broodstock, pay attention to the action is light and avoid damaging the fish's skin and scales. Do not use fish with more severe mechanical damage as a broodstock for the following year. Treatment of hydromycosis can be carried out with 3%~6% saline solution for 10 minutes, or with gallnut drowning Quanchiposa. Treatment of white skin disease can be bleached powder Quanchiposa.
