Short description Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 45-54; Anal spines: 0; Anal soft rays: 36 - 42. Caudal fin margin usually concave. Color is silvery on back, silvery whitish on belly. M. gayi gayi and M. gayi peruanus differ by the total number of vertebrae, total number of gill rakers and relative length of head (Ref. 1371).

Occurs from the shallow continental shelf to the upper continental slope (Ref. 1371). Sometimes found off the bottom or in midwater (Ref. 1371). Marketed fresh and frozen and also used for fishmeal (Ref. 1371).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00550 (0.00299 - 0.01011), b=3.09 (2.93 - 3.25), based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 4.4 ±0.6 se; Based on diet studies.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.19-0.21; tmax=13).

Vulnerability (Ref. 59153): Moderate to high vulnerability (54 of 100) .

Price category (Ref. 80766): High.
