Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 16-19; Anal spines: 0; Anal soft rays: 19 - 23. Upper jaw with distinct median notch, into which tip of lower jaw fits. Lower gill rakers long, fine and numerous, about 3 times as long as gill filaments; upper gill rakers bent sharply upward, V-shaped. Caudal fin deep chrome, tips long and pointed.

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

Eastern Central Atlantic: Dakhla, Western Sahara to at least Lobito, Angola, corresponding to the extreme northerly and southerly limits of the 25°C isotherms throughout the year; dwarf population exist in Lake Nokoué, Benin. Cape Verde records based on erroneous type locality for Ethmalosa fimbriata by Bowdich - followed by later authors.

Biology     Glossary (e.g. epibenthic)

Occurs in inshore waters, lagoons and more than 300 km up rivers (e.g. Gambia River). Feeds by filtering phytoplankton, chiefly diatoms. Breeds throughout the year in waters of salinities 3.5-38 ppt, but with peaks in at least some areas. Spawns in the sea, in estuaries and rivers. Feeds on phytoplankton, chiefly diatoms. Marketed fresh, also smoked and dried.

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01020 (0.00864 - 0.01204), b=3.04 (2.99 - 3.09), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  2.5   ±0.0 se; Based on diet studies.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (K=0.25-0.36; tm=1; Fec=16,000).
Vulnerability (Ref. 59153):  Moderate vulnerability (41 of 100) .
Price category (Ref. 80766):   High.
