搞好鱼类的越冬管理,是池塘养鱼增产的重要措施之一。其主要措施有: 1 做好越冬前的准备 1.1 加强秋季培育因鱼类到了冬季就基本上停止摄食和生长,处于半休眠状态,仅靠消耗体内积存的脂肪维持生命,因此,要加强后期的饲养管理,多喂些豆饼、花生饼.棉子饼等脂肪和蛋白含量较高的精饲料。在饲料结构中加些能量饲料的比例,并且不要过早停食。这样,才能促使鱼体肥壮,提高抗寒、抗病能力 1.2 适当肥水越冬前追施几次粪肥,一般每次每亩水面50～100kg,使池水能繁殖较多的浮游生物,持别是浮游植物。它不仅是鱼的最佳饵料.而且可通
Improving winter management of fish is one of the important measures for raising fish production in the pond. The main measures are as follows: 1 to prepare for the winter before 1.1 to strengthen the autumn cultivation as the fish to the winter to basically stop feeding and growth, in a semi-dormant state, rely on the consumption of body fat accumulated to maintain life, therefore, to strengthen the late Feeding and management, feeding more bean cake, peanut cake. Cotton seed cake and other fat and protein content of high feed. Add some energy feed to the feed structure and do not stop eating too soon. In this way, in order to promote fish fat, improve cold resistance and disease resistance 1.2 Appropriate fertilizer before winter topdress several manures, usually per acre of water 50 ~ 100kg, so that the water can multiply more plankton, do not hold a plankton plant. It is not only the best fish food, but also through
