Length at first maturity / Size / Weight / Age

Maturity: Lm 21.2  range ? - ? cm
Max length : 40.0 cm NG male/unsexed; (Ref. 36453)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 75-89; Anal spines: 0; Anal soft rays: 60 - 71. Dark spots on ocular side irregularly and two dark small spots at end of both dorsal and anal fin bases on blind side symmetrically (Ref. 27363).

Biology     Glossary (e.g. epibenthic)

Feeds on amphipods, small crabs and polychaetes (Ref. 36453). In spring mature individuals migrate to 37°S and southwards to spawn and in autumn migrate offshore for feeding and growing (Ref. 41500).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00279 - 0.00861), b=3.17 (3.02 - 3.32), based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.49 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (32 of 100) .
