The invention relates to a method for discriminating acanthopagrus schlegelii, pagrosomus major and hybrid offsprings thereof based on morphological parameters. The method includes the following steps that the morphological parameters of a sparidae sample are measured, wherein the morphological parameters comprise total length, body length, body thickness, eye diameter and eye posterior segment length; discriminant equations for an acanthopagrus schlegelii selfing group, a pagrosomus major selfing group, a female pagrosomus major and male acanthopagrus schlegelii hybridization group and a female acanthopagrus schlegelii and male pagrosomus major hybridization group are established; the obtained morphological parameters are substituted into the discriminant equation set to determine fish varieties. By means of the method, acanthopagrus schlegelii, pagrosomus major and hybrid offsprings thereof can be rapidly and accurately discriminated.
