Protein electrophoresis (PAGE) was used to study the three morphologically different species of Spicara (S. flexuosa, S. maena, S. smaris). Of the 28 enzymatic and additional myogenic loci, five monomorphic loci (LDH‐1*, G6PD‐1*, PGI‐1* and two PMMs*) were species‐specific markers of S. smaris with respect to S. flexuosa and S. maena. Four of the 28 enzymatic loci were polymorphic (EST‐1*, GLDH*, PEPD*, PGI‐2*). Discriminating genetic markers were not identified between S. flexuosa and S. maena. Genetic distance (D) as calculated by Nei's index (1978), between S. smaris v. S. maena and S. flexuosa showed a value, respectively of Z) = 0·137 and 0·141. Between S. flexuosa and S. maena the value was Z)=0‐006. From the data it can be inferred that S. flexuosa and S. maena are conspecific, despite morphological differences.
