Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00372 (0.00165 - 0.00837), b=3.41 (3.22 - 3.60), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level
(Ref. 69278) 		3.2   ±0.40 se; based on food items.
Resilience
(Ref. 120179) 		Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 1,206).
Fishing Vulnerability
(Ref. 59153) 		Moderate vulnerability (40 of 100). 🛈
