Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00955 (0.00430 - 0.02123), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		2.0   ±0.00 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) 		Moderate to high vulnerability (55 of 100). 🛈
Price category
