Biology     Glossary (e.g. epibenthic)

Adults spawn apparently during autumn and early winter. Hatching probably occurs in spring and size at hatching at about 12 mm TL. Main food items are polychaetes and benthic crustacean (Ref. 5192). Larval pelagic phase is short (Ref. 41551).

Estimates based on models

Preferred temperature (Ref. 115969): -1.8 - 0.9, mean -1 (based on 273 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00257 (0.00167 - 0.00396), b=3.15 (3.02 - 3.28), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.3 se; based on diet studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec < 10,000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
