| Different colors | |
| Remarks | Females seem to be larger than males; apparently this is due to the fact that females reach a greater age as well as to the difference in the growth rate (Ref. 10538). |

| Diagnosis |
Diagnosis: This species is distinguished from other species of Alosa entering freshwater in the Mediterranean basin by: dorsal profile convex; 40-60 thin gill rakers in individuals larger than 200 mm standard length, with 25 to 38 on its lower part; and no teeth on palatine (Ref. 10538, 59043). Description: Dorsal profile convex (Ref. 59043). Upper jaw with median notch (Ref. 59043). There are 40-60 gill rakers on the first arch with 25-38 on its lower part (Ref. 10538, 13696, 59043). Total number of dorsal fin rays 18-22; total number of anal fin rays 20-25; total number of pelvic fin rays 9 (Ref. 10538). Scales in a longitudinal series 58; scales in a transverse series 20; elongated scales at base of caudal fin lobes (Ref. 11601, 59043). Number of pre-pelvic ventral scutes 19-23; number of post-pelvic ventral scutes 13-16; total number of ventral scutes: 33-39 (Ref. 10538). Number of vertebrae: 53-57 (Ref. 10538). |
