Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 5 - 6; Rückenflossenweichstrahlen (insgesamt) : 6 - 8; Afterflossenweichstrahlen: 5 - 7. Unpaired breast row of plates absent, but paired plate rows cover whole breast. Snout with a pair of strong spiny hooks; numerous barbels on branchiostegal membranes. Dorsal plates 31-34 (Ref. 232). Spiny and soft dorsal fins almost fused. No spines on the hind part of the head (Ref. 35388).

Inhabits inshore waters, deeper waters in winter in Skaggerak, preferring sandy bottoms, rarely with stones. Maximum depth reported at 270 m (Ref. 28197). Temp. range: 4.0-8.0 °C. Feeds on bottom crustaceans and polychaetes. Matures after about 1 year; a few spawning in the second year (Ref. 722). The eggs are laid in seaweed (Ref. 9900). Spawns in February - April, female laying 2,500-3,000 yellow eggs with a diameter of 2 mm. Period of development is very long and 6-8 mm long pelagic larvae hatch after 10-11 months (Ref. 35388).

Estimates based on models

Preferred temperature (Ref. 115969): 7 - 11.7, mean 9.2 (based on 442 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00397 - 0.02640), b=2.99 (2.77 - 3.21), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.3 se; based on diet studies.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (K=0.47; tm=1-4; tmax=3; Fec=2,400).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (26 of 100).
