What season is the best for raising fish?

This question is difficult to answer. Fish like to eat in spring and are weak, but they are anorexic when the temperature is high in summer and have a good appetite in autumn. In order to supplement the nutrition needed in winter, they hibernate when it is cold in winter. Generally speaking, imitating a small ecological environment in autumn is beneficial to the growth and development of fish. But it is necessary to change all the year round, which is essential.
