Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.4   ±0.22 se; based on food items.
جهندگی (Ref. 120179):  زياد, كمينه زمان لازم براي دو برابر شدن جمعيت ، كمتر از 15 ماه (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (16 of 100).
