Bayesian length-weight: a=0.01175 (0.00571 - 0.02419), b=3.04 (2.88 - 3.20), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.7 ±0.5 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (24 of 100).
