(Ref. 82804) 		PD50 = 0.7520 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.01230 (0.00620 - 0.02443), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level
(Ref. 69278) 		4.0   ±0.66 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 vulnerability (38 of 100). 🛈
