北方地区的越冬池,一般都有面积大、鱼池深,又有补水条件等优点,很适合搞集约化养鱼,特别是近年来各地养殖单位用它来搞驯化养鱼种后原池座塘越冬,又具有损伤少、易管理、省水电、产量和越冬成活高等优。但也有些初搞的地方因缺乏掌握关键性技术和管理措施,出现了驯化产量低,越冬效果差等不利现象。为此,介绍几条关键性措施供参考应用。 The wintering ponds in northern China generally have the advantages of large area, deep fish ponds, supplemental water conditions, etc., and are very suitable for intensive fish farming. In particular, aquaculture units around the country have engaged in the domestication of fish ponds in recent years Wintering, but also with less damage, easy to manage, provincial water and electricity, yield and survival of the higher winter superiority. However, some places that were initially engaged failed to grasp the key technologies and management measures, resulting in unfavorable phenomena such as low domestication yield and poor winter wintering effect. To this end, introduce a few key measures for reference applications.
