There are ways to rejuvenate weak fish species in autumn.
Due to the hot summer climate, aging water quality and feeding management and other reasons, the physique of fish species raised by many farmers is weak. If these weak fish species are not rejuvenated in time when the autumn is high and cool, it is not conducive to the overwintering of fish species, and will greatly affect the annual output in the coming year. Therefore, it is very important to rejuvenate weak fish species in autumn. The methods of rejuvenation of weak fish species in autumn are introduced as follows: after the high temperature season of turning ponds and Qingtang in spring and summer, the general water quality is aging, the natural organisms are reduced, and the harmful bacteria are increased, which is not conducive to the fish.
