摘要
淡水鲳亲鱼经温水越冬,强化培育,其性腺可提早成熟。采用常规催产技术可提早产卵。孵化所得的鱼苗育成夏花鱼种,当年即可养成商品鱼。
The brood fish of Piaractus brachypomus could reach sexual maturity earlier than usual by means of warm water over-wintering and intensive cultivation. The matured fish could be induced to spawn through conventional methods. The fish summerlings obtained from fry intensive rearing could grow into the marketable sizes in the same year.
