50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00520 - 0.01924), b=3.09 (2.93 - 3.25), in cm total length, based on LWR estimates for species & Subfamily-BS (Ref.

Trophic level (Ref.
69278): 2.7 ±0.22 se; based on food items.
Widerstandsfähigkeit (Ref.
120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (tm = 0.13; tmax = 0.33; Batch Fec = 1-7;).
Fishing Vulnerability (Ref.
