北方地区由于地理条件的特殊,其气候不同于我国南方气候,养殖周期短,因此在养殖过程中的管理也不同于我国南方地区。为了加快养殖鱼类的生产进程,缩短养殖周期,加强鱼池的季节管理也就至关重要。1 春季管理1.1 随着春季的到来,气温逐渐回升,北方地区池塘中的冰快逐步融化,鱼类的活动也逐渐增强,此时经过长期越冬的鱼体体质有待于恢复,这时水质的好坏会严重影响鱼类摄食。由于经过越冬的池水严重老化,水体pH值
Due to the special geographical conditions in the north, the climate is different from the climate in southern China and the breeding cycle is short. Therefore, the management in the breeding process is also different from that in southern China. In order to speed up the process of farmed fish production and shorten the breeding cycle, it is also very important to strengthen the seasonal management of fish ponds. 1 Spring Management 1.1 With the arrival of spring, the temperature gradually rose. The ice in ponds in the northern part of China gradually melted and the activity of fish gradually increased. At this moment, the body of the fish which had been overwintered for a long time had to be recovered, and the water quality was good Bad will seriously affect the fish feeding. Due to severe winter water over winter, water pH
