Maturity: Lm ?  range ? - ? cm
Max length : 42.0 cm SL male/unsexed; (Ref. 5192)
Yolk larvae (2.3-3.2 cm TL) found from late October to early December; small juveniles from mid-January to mid-March, thus hatching may occur in late winter. Feeds on fish (Ref. 5192).

Phylogenetic diversity index (Ref. 82804
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00214 (0.00129 - 0.00354), b=3.21 (3.05 - 3.37), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 4.2 ±0.7 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
