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) 		3.4   ±0.59 se; based on food items.
Resilience
(Ref. 120179) 		Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153) 		High vulnerability (60 of 100). 🛈
