Bayesian length-weight a=0.00141 (0.00076 - 0.00263), b=3.43 (3.27 - 3.59), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level
(Ref. 69278) 		3.9   ±0.65 se; based on food items.
Resilience
(Ref. 120179) 		Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153) 		Moderate to high vulnerability (47 of 100). 🛈
