Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00331 - 0.00870), b=3.26 (3.12 - 3.40), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.1 ±0.63 se; based on food items.
Generation time: 6.9 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
جهندگی (Ref.
120179): پايين ، كم, كمينه زمان لازم براي دو برابر شدن جمعيت 5/4 – 14 سال (K=0.10).
Fishing Vulnerability (Ref.
