Bayesian length-weight a=0.00047 (0.00025 - 0.00088), b=3.28 (3.12 - 3.44), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		4.0   ±0.6 se; based on size and trophs of closest relatives
Resilience
(Ref. 120179) 		Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 8,000-12,000).
Fishing Vulnerability
