Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.0   ±0.2 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 120179):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (tmax=12).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100). 🛈
