Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 13; Dorsal soft rays (total): 14 - 15; Anal spines: 0; Anal soft rays: 13 - 14; Vertebrae: 39.

Found in oceanic waters, sometimes not far from the coast (Ref. 13628). Forms large mixed schools with the skipjack tuna. Its spawning grounds are located well offshore. Preys on surface and deep-sea fishes, squids, amphipods, shrimps, crabs and stomatopods and decapod larvae. The largest fishery for blackfin tuna operates off the southeastern coast of Cuba and uses live-bait and pole. Utilized fresh, dried or salted, canned and frozen (Ref. 9987).

Estimates based on models

Preferred temperature (Ref. 115969): 10 - 20.5, mean 14.4 (based on 163 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01148 (0.00699 - 0.01886), b=3.05 (2.91 - 3.19), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.4 ±0.3 se; based on diet studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.22; tm=3; tmax=5).

Prior r = 0.77, 95% CL = 0.51 - 1.16, Based on 1 data-limited stock assessment.

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100).
