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=0.00676 (0.00311 - 0.01469), b=3.10 (2.93 - 3.27), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.5 se; based on size and trophs of closest relatives
جهندگی (Ref.
120179): زياد, كمينه زمان لازم براي دو برابر شدن جمعيت ، كمتر از 15 ماه (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
