Length at first maturity / Tamaño / Peso / Age

Maturity: L_m 103.5, range 99 - 108 cm
Max length : 150 cm TL macho / no sexado; (Ref. 244)

Found on the continental and insular shelves, often occurring in shallow water close inshore. Prefers estuaries and shallow bays, especially sandy and algal-covered areas and eelgrass flats. Feeds on small fishes and probably crustaceans and other benthic invertebrates. Often solitary, though some may cluster in resting areas on bottom. Ovoviviparous (aplacental), with 10 to 20 young in a litter. Meat is regarded as of inferior quality.

Estimates based on models

Preferred temperature (Ref. 123201): 14.8 - 21.8, mean 18.8 °C (based on 52 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00240 (0.00110 - 0.00521), b=3.14 (2.96 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.8 ±0.2 se; based on diet studies.

Generation time: 6.7 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resiliencia (Ref. 120179): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Fec=10; K=0.16; tmax=20.6).

Fishing Vulnerability (Ref. 59153): High vulnerability (64 of 100).

Price category (Ref. 80766): High.
