As far as fry is concerned, it should be small-sized fish of that year, and the size is generally within 10cm. Then, the best stocking time should be determined according to your stocking waters and production methods. If you are going to sell large-scale fry specially produced and bred, you can buy sea flowers that have just come out of the circle (that is, just hatched) for breeding. At this time, carp and crucian carp fry will be listed in Hunan in mid-March and will be stocked.

Large fish can also be cultivated, so summer flowers of carp, crucian carp and other fish can be cultivated at the end of March, and summer flowers of grass, silver carp and other fish can be cultivated at the end of May and beyond. If you are going to breed large-scale commercial fish that can be listed at the end of the year, you can breed your own fry, or you can buy large-scale fry or fish raised by others, usually in autumn or winter, and most of them are large fish in autumn.
