Biology     Glossary (e.g. epibenthic)

Adults inhabit soft muddy to moderately hard bottoms (Ref. 5951). Feed predominantly in daytime on organisms living in, on or near the bottom; shrimps, amphipods, crabs, sea urchins and snails (Ref. 12232). Batch spawner (Ref. 51846).

Estimates based on models

Preferred temperature (Ref. 123201): 0.7 - 13.1, mean 6.1 °C (based on 303 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00493 - 0.01404), b=3.08 (2.93 - 3.23), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.1 se; based on diet studies.
Generation time: 3.5 (2.6 - 4.2) years. Estimated as median ln(3)/K based on 20 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.11-0.7(?); tm=2-3; tmax=10).
Prior r = 0.16, 95% CL = 0.10 - 0.23, Based on 3 full stock assessments.
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (34 of 100).
