  • Growth / growth performance : Sabatié, 1990 | Sabatié et al., 1996 .
  • Habitat / home range : amphihaline species, schooling and strongly migratory, penetrating far up rivers (but not into small tributaries). Adults are usually found in open waters along the coast. In freshwater, inhabits major rivers but may also enter tributaries .

  • Migration / movement : Bauchot, 1987 | Furnestin & Vincent, 1955 | Munroe, 2016b | Sabatié et al., 1996 .
  • Morphology / anatomy : Bauchot, 1987 | Fischer et al., 1981b | Munroe, 2016b | Sabatié et al., 1996 | Whitehead, 1967a | Whitehead, 1981 | Whitehead, 1985 .
  • Reproduction : known lake populations from Morocco need access to rivers to spawn. Larvae and small juveniles inhabit deep slow-flowing areas of rivers, some swimming upstream in late summer and autumn. Juveniles (up to 1+ years) are usually found near estuaries or river mouths, possibly making vertical diurnal movements synchronized with the tides; they remain in estuaries for over one year .

  • Size : up to 600 mm SL; 2.7 kg .
