Bayesian length-weight a=0.00977 (0.00625 - 0.01527), b=3.11 (2.98 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level
(Ref. 69278) 		3.8   ±0.2 se; based on diet studies.
Resilience
(Ref. 120179) 		Low, minimum population doubling time 4.5 - 14 years (tmax=22; K=0.16).
Fishing Vulnerability
(Ref. 59153) 		Moderate to high vulnerability (50 of 100). 🛈
