2 hybrids of ♂ were comprehensively analyzed in six countable morphological parameters, 10 meristic parameters and 24 truss framework parameters. ANOVA showed that the countable parameters of the F₁ and F₂ hybrids were intermediate betweenexcept for the same number of spines in the anal fin. For the meristic and truss framework parameters, the F₁ hybrid was larger than 3-5/total length, 5-7/total length, and O. niloticus in body width/total length, body height/total length, truss parameter /total length, and caudal peduncle height/total length. The F₂ hybrid showed no significant difference with the F₁ hybrid in 16 meristic and truss framework parameters; however, the F₂ hybrid was larger than the F₁ hybrid in head length/total length, truss parameter /total length, and hybrid in body length/total length, caudal peduncle length/total length, truss parameter /total length, and 2 hybrid stock was initially clustered with the F₁ hybrid stock, then they were clustered with . Discriminant fomulations for the four stocks were developed with countable and measurable parameters, and the order of discriminant accuracy for these stocks was 2 hybrid. More F₁ hybrid individuals were assigned to (92.9% in countable formula, 57.1% in measurable formula) than and hybrid individuals were assigned to F₁ hybrids by the discriminant formula of hybrid (68.6% in countable formula, 77.2% in measurable formula). Principal component analysis showed that the scatter plots of the F₁ and F₂ hybrids were distributed between hybrid showed more overlapping with S. melanotheron. The above results showed that the hybrid inherited the morphological traits of their parents with some maternal inheritance. The F₂ hybrid inherited some morphological parameters from the F₁ hybrid, but also showed some distinct variations in other parameters.
