The culturing of broodstock in culturing broodstock
According to the quality of broodstock and the characteristics of gonadal development, cultivating should be divided into stages and focus. 1, the spring training that prenatal training, time 3 to 5 months. The focus is to promote the development and maturation of the gonadal, and strive to eat food as early as possible. The amount of feed should be sufficient, and appropriate amounts of fresh feed should be fed; and the flushing should be strengthened to prevent the brooding pond from lacking oxygen and floating heads. 2. Cultivation in summer is postnatal and postnatal. The time is from June to August. At this time, the sexual product is gradually absorbed by the fish, but the water temperature is high, and the water temperature must be controlled and adjusted within the appropriate temperature range by adding water or increasing the water depth. The feed should be sufficient to restore the physical strength and damage caused by breeding. . 3, the autumn cultivation time is from September to November, the gonad gonad enters a new round of development period, and the cultivation will directly affect the sexual maturity of the second year. First of all, we should pay attention to regulating water quality, maintaining adequate water depth for winter, checking for potential diseases to prevent winter deaths, and secondly, we must invest enough to increase some fat and protein components, so that the gonadal development and winter consumption before winter Lay a good foundation. 4. Winter cultivation From December to March of the following year, the wintering period is the main reason. In most regions, except for individual weather, feed is generally not provided to control water quality and prevent freezing and lack of oxygen. However, there are differences between South and North China. For example, during the wintering period in South China is very short (December to January). When the temperature is appropriate, as long as the broodstock feeds, some feed should be properly fed because the wintering time is short. Detrimental to gonadal development, through intensive cultivation, can get some compensation.
