After fattening in the pond in autumn, the fish species are generally strong and easy to adapt to the cage environment. At the same time, when the caisson overwintered with large water surface, not only the body weight consumption of the fish species overwintering was less than that in the pond, but also the fish began to eat earlier after overwintering in spring, and the growth period was about one month longer than that of the fish in the box in spring.
