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=0.01000 (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): 3.2 ±0.5 se; based on size and trophs of closest relatives
جهندگی (Ref.
120179): متوسط, كمينه زمان لازم براي دو برابر شدن جمعيت 4/1 – 4/4 سال (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
