Uses: no uses
Comments: From reports, whereas 8,000 tons of this species were landed in 1986 (in Carneiro and Castro, 2005, as M. ancylodon), the catch decreased to 4,000 tons in 2002 (a decline in commercial stocks of at least 50% over this 16-year period). In southern Brazil, demersal resource stocks evaluation obtained from 1975 to 1994 show a decreasing total biomass since the beginning of exploitation and that the resource is heavily exploited in that region (Haimovici, 1998, as M. ancylodon) (Ref. 88197).

Short description Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 27-29; Anal spines: 2; Anal soft rays: 8 - 10. Macrodon atricauda differs from M. ancylodon by the following characteristics: pored lateral line scales 49-63 (vs. 66-78); anal fin soft rays 9-10, rarely 8 (vs. usually 8, occasionally 9); dorsal fin soft rays 27-28, rarely 29 (vs. 28-29, rarely 27); pectoral fin rays 16-17 (vs. 15-16); largest front canines 2.5 to 3.2 in eye length, proportionally smaller and thinner when compared to M. ancylodon (Ref. 88197).

This species is heavily exploited throughout its range (Ref. 88197).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00617 (0.00404 - 0.00942), b=3.09 (2.96 - 3.22), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (36 of 100).
