Marine; freshwater; brackish; pelagic-neritic; catadromous (Ref. 51243); depth range 10 - 20 m (Ref. 7399). Temperate; 64°N - 20°N, 26°W - 42°E

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Eastern Atlantic: Scotland to Cape Verde; in the Mediterranean and Black Sea. Also in coastal waters from southern Norway to Morocco, rare off Mauritania (Ref. 3573). Records from the lagoon of Accra are probably misidentifications.

Max length : 61.0 cm FL male/unsexed; (Ref. 117745); common length : 30.0 cm SL male/unsexed; (Ref. 7399); max. published weight: 2.5 kg (Ref. 117745)

Short description Morphology | Morphometrics

Dorsal spines (total): 5; Dorsal soft rays (total): 7-9; Anal spines: 3. Longer pectoral fins, lack of black spot at the pectoral fin base. Golden spot present in gill cover (Ref. 35388).

Biology     Glossary (e.g. epibenthic)

Adults are neritic usually in schools, entering lagoons and lower estuaries (Ref. 7399); rarely entering freshwater (Ref. 3573, 59043). Juveniles move to coastal lagoons and estuaries in winter and especially in spring (Ref. 59043). They feed on small benthic organisms, detritus, and occasionally on insects and plankton (Ref. 2804). Juveniles feed only on zooplankton (Ref. 59043). Reproduction takes place in the sea, from July to November. Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Minimum size allowed for fishing is 20 cm. The quality of the flesh is variable (Ref. 30578).
