一、加强秋后饲养,增强体质。金鱼在最适水温20℃～28℃范围时,水温越高新陈代谢越旺盛,生长越快。当水温降至5℃以下时则休眠越冬。我国大部分地区11月至翌年3月为金鱼的越冬期。应在越冬前1个月加强饲喂管理。多投喂蛋白质、脂肪含量高的优质饲料,如蛋黄、蚕蛹、蚯蚓、黄粉虫等,让它尽量多贮备一些能量,提高抗寒、抗病能力,以便安全越冬。二、严格消毒杀菌,防止病害。金鱼在越冬前和越冬后都应彻底
First, to strengthen autumn feeding, enhance physical fitness. Goldfish in the optimum temperature 20 ℃ ~ 28 ℃ range, the higher the water temperature the more prosperous metabolism, the faster the growth. When the water temperature dropped below 5 ℃ when the winter dormancy. Most parts of China from November to March the following year is the winter goldfish. Feeding management should be strengthened one month before winter. More fed protein, high fat content of high-quality feed, such as egg yolk, silkworm pupa, earthworms, Tenebrio, etc., let it reserve as much energy as possible, improve cold, disease resistance, in order to secure wintering. Second, strict disinfection and sterilization, prevent disease. Goldfish should be thoroughly harvested before and after winter
