50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00490 - 0.01121), b=3.00 (2.88 - 3.12), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.

Trophic level (Ref.
69278): 4.4 ±0.3 se; based on diet studies.
Generation time: 8.5 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Widerstandsfähigkeit (Ref.
120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
