Zusammenfassung: | The invention belongs to the field of crucian breeding, and discloses a breeding method for inhibiting gonad development of crucian fingerlings, according to the breeding method, the stocking density and the fingerling specification are reasonably controlled, quantitative feeding feed is matched, a temporary breeding mode is constructed, preparation is made for subsequent main breeding or polyculture, the routine of promoting gonad development of crucian by carps is broken, and the breeding efficiency is improved. The method effectively solves the problem that the breeding mode of breeding design is disturbed due to precocious puberty of crucian fingerlings and spawning in spring of the next year, so that the crucian accumulates more energy for self growth, the yield of the crucian is increased, and the same progress is made in the aspect of specification; and the breeding method is simple to operate, does not need to strictly control breeding conditions, and can be applied to fishery on a large scale.
