Profusion of dark spots on the body, head and fins. Dark in coloration (Ref. 37032).

Biology     Glossary (e.g. epibenthic)

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5781   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00269 (0.00115 - 0.00629), b=3.24 (3.04 - 3.44), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.66 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (tm=4; Fec=1,772).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
Price category (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 37.9 [23.5, 80.5] mg/100g; Iron = 0.781 [0.471, 1.202] mg/100g; Protein = 18.6 [17.7, 19.5] %; Omega3 = 0.271 [0.161, 0.458] g/100g; Selenium = 45.8 [25.3, 84.3] μg/100g; VitaminA = 6.17 [2.51, 14.71] μg/100g; Zinc = 0.573 [0.426, 0.794] mg/100g (wet weight);
