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=0.00324 (0.00142 - 0.00736), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.0 ±0.00 se; based on food items.
Generation time: 19.2 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
جهندگی (Ref.
120179): خیلی آهسته, كمينه زمان لازم براي دو برابر شدن جمعيت بيش از 14 سال (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (86 of 100).
