Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 13; Rückenflossenweichstrahlen (insgesamt) : 11 - 14; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 5 - 8; Wirbelzahl: 26. Head spines strong - nasal, preocular, postocular, tympanic and parietal spines present, supraocular, coronal and nuchal spines absent (Ref. 27437). Toothed knob in front of each upper jaw, deep notch between jaws (Ref. 27437). Caudal fin moderately indented (Ref. 6885). A red rockfish, silver ventrally (Ref. 27437). Branchiostegal rays: 7 (Ref. 36715).

Common offshore, on soft bottoms (Ref. 2850). Young occur in shallow water, often at surface under drifting kelp (Ref. 2850). Viviparous, with planktonic larvae and pelagic juveniles (Ref. 36715, 34817). The biggest individuals are sometimes found in markets where the flesh is sold as rockfish fillet (Ref. 27436). Rarely caught by anglers (Ref. 27436).)

Estimates based on models

Preferred temperature (Ref. 123201): 4.4 - 8.6, mean 5.9 °C (based on 131 cells).

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

Bayesian length-weight: a=0.01000 (0.00499 - 0.02004), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.39 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (tm=5; tmax=86; Fec=14,000).

Prior r = 0.12, 95% CL = 0.08 - 0.18, Based on 1 full stock assessment.

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (36 of 100).

Preiskategorie (Ref. 80766): Medium.
