鱼种在进入冬季后，随着水温的下降，其新陈代谢作用逐渐减弱，食欲也相应减退，体质变得较虚弱，易遭敌害生物的攻击和致病菌的侵袭，严重影响了池塘鱼种的越冬成活率。因此，如何保证亲鱼顺利越冬，是池塘养鱼生产中的一个重要环节。通过多年的生产实践，我们积累了一些提高 After entering winter, with the decrease of water temperature, the metabolism of fish gradually weakened and the appetite decreased correspondingly. The constitution became weaker and vulnerable to attack by attacking organisms and pathogenic bacteria, which seriously affected the fish species Overwintering survival rate. Therefore, how to ensure the successful winter wintering broodstock is an important part of fish production in ponds. Through years of production practice, we have accumulated some improvements
