50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00426 - 0.01291), b=3.13 (2.98 - 3.28), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.3 ±0.46 se; based on food items.
Generation time: 1.7 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
回复力 (Ref.
