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

Eastern Central Atlantic: Senegal to Gabon; also Cape Verde, São Tome-Principe Islands, and Rolas Islands. There is little doubt that only a single species of Lethrinus exists in the tropical western Atlantic.

Length at first maturity / Size / Weight / Age

Maturity: L_m 22.8, range 21 - ? cm
Max length : 50.0 cm TL male/unsexed; (Ref. 2295); common length : 30.0 cm TL male/unsexed; (Ref. 2295)

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 10; Dorsal soft rays (total): 9; Anal spines: 3; Anal soft rays: 8. The outer surface of the maxilla is smooth, without a knob or pronounced longitudinal ridge. Inner surface of the pectoral fin axil without scales. Overall color is olive green or brown and pinkish. The cheeks have a network of fine reticulations below the eye.

Found in shallow coastal waters (Ref. 2263). Feeds mainly on bottom-dwelling invertebrates. Marketed fresh (Ref. 171), smoked and dried salted (Ref. 2295). Abundant during the winter months (Ref. 2683).

Estimates based on models

Preferred temperature (Ref. 115969): 24.4 - 28, mean 26.6 (based on 60 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01479 (0.00917 - 0.02386), b=2.95 (2.82 - 3.08), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.46 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=2).

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).

Climate Vulnerability (Ref. 125649): High to very high vulnerability (74 of 100).

Price category (Ref. 80766): Very high.
