Biology     Glossary (e.g. epibenthic)

A sedentary rockfish found in shallow water and bays (Ref. 2850), among sheltering weed-covered rocks or around pilings (Ref. 27436). Viviparous, with planktonic larvae and pelagic juveniles (Ref. 36715). Fin spines are sharp and mildly venomous and can cause annoying wounds (Ref. 27436). Small live specimens make excellent bait for large lingcod (Ref. 27436). Flesh is firm and tasty, but rarely found in markets (Ref. 26346).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00360 - 0.03662), b=3.00 (2.74 - 3.26), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.62 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (tmax=34; tm=5).
Vulnerability (Ref. 59153):  High vulnerability (58 of 100) .
Price category (Ref. 80766):   Medium.
