Bayesian length-weight a=0.01072 (0.00936 - 0.01227), b=3.03 (3.01 - 3.05), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level
(Ref. 69278) 		4.0   ±0.52 se; based on food items.
Resilience
(Ref. 120179) 		Medium, minimum population doubling time 1.4 - 4.4 years (K=0.21-0.86; Fec=4,165).
Fishing Vulnerability
(Ref. 59153) 		Low to moderate vulnerability (27 of 100). 🛈
