| Scientific Name with Original Description | | | Clupea maderensis Lowe, 1839(June), Trans.zool.Soc.Lond., 2(3):189 (Madeira) (wrongly dated 1841 in some publications, e.g. CLOFNAM). |
| Diagnostic Features
| | | Body elongate, but variable in depth, belly fairly sharply keeled; total scutes 31 to 34.
Lower gillrakers 70 to 166 (in fishes 6 cm standard length or more).
Upper pectoral finrays white on outer side, the membrane between black. Resembles S. aurita, but pelvic finrays i 7 (i 8 in S. aurita ) and no black spot on hind part of gill cover (but faint gold or black area just behind gill opening). Distinguished from S. rouxi by having more lower gillrakers (only 30 to 40 in S. rouxi ) and the caudal fin grey, its tips almost black (yellow in S. rouxi ).
|
| Geographical Distribution | |
| | Mediterranean (southern and eastern parts, also penetrating Suez Canal); eastern Atlantic (Gilbraltar southward to Angola and a single recorded specimen from Walvis Bay, Namibia). |
| Habitat and Biology | | Coastal,pelagic,but tolerant of low salinities in estuaries,
schooling, preferring waters of 24° C, at surface or at bottom down to 50 m, strongly migratory.Feeds on a variety of small planktonic invertebrates, also fish larvae and phytoplankton.
Breeds only once in the year, during the warm season (July-September), in coastal waters.
Juveniles and adults show clear north-south migrations in the Gabon Congo-Angola sector of their' range and also in the Sierra Leone -Mauritania sector, each area having nurseries; the movements are correlated with the seasonal upwelling. Migrations in the central part (Ivory Coast-Ghana) are not so marked. |
| Size | | | To 30 cm standard length, usually to 25 cm. |

Global Capture production for
Sardinella maderensis
(FAO Fishery Statistic) |  | 
 |
|
Of considerable importance off West African coasts, but combined with S. aurita in most statistics, partly because the two are often caught together. The total catch reported for this species to FAO for 1999 was 146 097 t. The countries with the largest catches were Senegal (105 120 t) and Latvia (15 031 t).
| |  Related Fishing Techniques |
| Remarks | | Many more West African references in the literature (right up to the present time) give this fish as S. eba a substantial number use the name S. cameronensis for fishes caught in the Cameroon area. Attempts to distinguish three species, however, remain unconvincing in view of the considerable variation in body depth and, most likely, gillraker numbers.
