目前,有些养鱼户还不重视或不习惯将养鱼生产中的各种原始数据和具体情况详细记录下来,以致无法很好地总结经验教训。 建立养鱼生产日志,相当重要,也比较简单,只要详细记录如下几项内容就可以了: 1、天气情况:记录每天的最低与最高水温。最低水温于日出前测量,最高水温在午后测量。 2、投饲情况:记录投饲的时间、种类和数量等。 3、水质情况:记录水色、pH值、溶氧量、透明度等情况及水生生物活动情况。
At present, some fish farmers do not pay attention to or are accustomed to keeping a detailed record of the various raw data and situations in fish production so that they can not properly sum up their experiences and lessons. The establishment of fish production log, is very important, but also relatively simple, as long as detailed records of the following items on it: 1, the weather conditions: record the daily minimum and maximum water temperature. The minimum water temperature measured before sunrise, the maximum water temperature measured in the afternoon. 2, feeding situation: record feeding time, type and quantity. 3, water quality: record aqua, pH, dissolved oxygen, transparency, etc. and aquatic biological activities.
