(Ref. 82804) 		PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
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) 		4.1   ±0.7 se; based on size and trophs of closest relatives
Resilience
(Ref. 120179) 		Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153) 		High vulnerability (59 of 100). 🛈
