Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 49-54; Anal spines: 0; Anal soft rays: 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=0.00776 (0.00496 - 0.01215), b=3.00 (2.87 - 3.13), 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): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

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

Price category (Ref. 80766): Unknown.
