Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 12 - 14; Rückenflossenweichstrahlen (insgesamt): 14; Afterflossenstacheln 3; Afterflossenweichstrahlen: 6 - 8; Wirbelzahl: 27. This species is distinguished by the following characters: 8 head spines strong - nasal, preocular, supraocular, postocular, tympanic, coronal, parietal and nuchal spines; 2 or more infraorbital spines; differs from S. melanostictus by having a pale body with no distinct spots on the membranes of the spinous dorsal fin; shorter dorsal-fin spine 1, 1.5?3.0 times into orbit length, 4.3?7.2% SL (vs. 1.0?1.8 times into orbit length and 5.9?9.6% SL); shorter dorsal-fin spine 4, 9.8?15.5% SL (vs. 12.0?18.4% SL); shorter and fewer gill rakers, 3.4?6.3% SL (vs. 3.9?7.1% SL) and 29?34 (vs. 30?36), respectively (Ref. 87139).

Usually found offshore (Ref. 27437). Viviparous (Ref. 34817).

Estimates based on models

Preferred temperature (Ref. 123201): 1.1 - 6.6, mean 3.8 °C (based on 232 cells).

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

Bayesian length-weight: a=0.00851 (0.00542 - 0.01337), b=3.12 (2.99 - 3.25), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.2 se; based on diet studies.

Generation time: 18.3 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Widerstandsfähigkeit (Ref. 120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (tmax=205).

Prior r = 0.03, 95% CL = 0.02 - 0.05, Based on 1 stock assessment.

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (74 of 100).

Preiskategorie (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 11.9 [4.4, 36.8] mg/100g; Iron = 0.229 [0.094, 0.634] mg/100g; Protein = 17.4 [16.2, 18.8] %; Omega3 = 0.635 [0.243, 1.657] g/100g; Selenium = 55.3 [18.9, 166.5] μg/100g; VitaminA = 8.1 [1.9, 35.6] μg/100g; Zinc = 0.287 [0.150, 0.547] mg/100g (wet weight);
