Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 49 - 54; Espinas anales: 0; Radios blandos anales: 32 - 38.

Obligate air-breathing (Ref. 126274); Can stay out of the water for 3 to 4 days at temperatures ranging from 10 to 15°C (Ref. 37350). Is a typical ambush predator that lies in wait for its prey on the bottom. Hunts mainly in the morning and in the evening, feeding primarily on fish (Ref. 12569). Matures at the age of 2 years and length of 30 cm. Spawns in June and July (Ref. 56557). Eggs are pelagic. Utilized for human consumption.

Estimates based on models

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

Bayesian length-weight: a=0.00741 (0.00490 - 0.01121), b=3.00 (2.88 - 3.12), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 4.4 ±0.3 se; based on diet studies.

Generation time: 8.5 ( 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 (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (62 of 100).

Price category (Ref. 80766): Unknown.
