秋、冬季是亲鱼育肥和性腺发育的重要阶段。冬季水温低,鱼的活动力差,食量大大减退,处于越冬阶段。所以,在秋季、冬前要给亲鱼创造良好的营养条件,促使亲鱼积累大量脂肪,顺利越冬,并为性腺发育准备必要的养料。草、青鱼池如草料、螺蛳等饲料供应不足,要投喂适量的麸皮、米糠等精料,每天每尾用干料量为100—150克。当水温下降后,亲鱼摄食量逐渐减少,可隔天投饲1次,每次投饵量也
Autumn and winter are important stages of broodstock fattening and gonadal development. Low winter temperatures, poor fish activity, food intake greatly reduced, in the winter stage. Therefore, in the fall and winter before the broodstock to create good nutrition conditions, to promote the broodstock to accumulate large amounts of fat, smooth winter, and gonadal development necessary nutrients. Grass, fish ponds such as grass, snails and other feed shortages, to be fed the right amount of bran, rice bran and other fine materials, the amount of dry material per day per tail is 100-150 grams. When the water temperature dropped, broodstock food intake gradually reduced, feeding one day can be the next day, each feeding amount is also
