Bayesian length-weight a=0.01288 (0.00658 - 0.02524), b=3.04 (2.88 - 3.20), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level
(Ref. 69278) 		3.2   ±0.48 se; based on food items.
Resilience
(Ref. 120179) 		Low, minimum population doubling time 4.5 - 14 years (K=0.13; tmax=12).
Fishing Vulnerability
(Ref. 59153) 		Moderate vulnerability (38 of 100). 🛈
