Enzymatic variation in African clariid catfishes Teugels, G.G. Guyomard, R. /Legendre, Marc POISSON D'EAU DOUCE EXPERIMENTATION HYBRIDE POLYMORPHISME ENZYMATIQUE APPLICATION AQUACULTURE Enzymatic polymorphism was examined at 13 protein loci in four African clariid catfish species : Claria anguillaris (Linnaeus, 1758), C. gariepinus (Burchell, 1822) and Heterobranchus longifilis Valencienne, 1840. The latter appears to be closer to C. anguillaris and C. gariepinus than C. ebriensis. These results correspond with recently published karyological and morphometrical data. Reproductive compatibility, under laboratory conditions at least, is demonstrated between C. gariepinus and H. longifilis. The hybrids were shown to be completely intermediate between the parental strains.
