Descrição suscinta Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 15 - 17; Raios dorsais (total) : 8 - 9; Espinhos anais: 3; Raios anais : 4 - 5. Head spines very strong - nasal, preocular, supraocular, postocular, tympanic, parietal and nuchal spines present, coronal spines absent; large head and elongate body; strong spiny ridge on head; 3rd dorsal spine not much longer than 2nd, 4th or 5th; strong notch on pectoral fin (Ref. 27437). Bright red with some black on fins; gill chamber mostly pale (Ref. 27437). Caudal slightly rounded (Ref. 6885).

Very common on soft bottoms (Ref. 2850). Oviparous (Ref. 205). Eggs are extruded in floating gelatinous masses (Ref. 31279). Have a thick glandular tissue on posterior margin of fin spines which is believed to be venomous (Ref. 57406). Rarely taken by game fishers (Ref. 27436). Flesh sweeter than that of other rockfishes (Ref. 27436).

Estimates based on models

Preferred temperature (Ref. 115969): 1.2 - 6.7, mean 3.8 (based on 417 cells).

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00708 (0.00408 - 0.01228), b=3.16 (3.00 - 3.32), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nível Trófico (Ref. 69278): 3.6 ±0.3 se; based on diet studies.

Resiliência (Ref. 120179): Muito baixo(a), tempo mínimo de duplicação da população maior que 14 anos (tmax> 100 (validated age: 62 yrs); tm= 13; Fec > 10,000).

Prior r = 0.03, 95% CL = 0.02 - 0.05, Based on 2 full stock assessments.

Fishing Vulnerability (Ref. 59153): High vulnerability (59 of 100).

Climate Vulnerability (Ref. 125649): Moderate vulnerability (38 of 100).

Categoria de preço (Ref. 80766): Very high.
