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=0.00813 (0.00372 - 0.01775), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.4 se; based on size and trophs of closest relatives
جهندگی (Ref.
120179): پايين ، كم, كمينه زمان لازم براي دو برابر شدن جمعيت 5/4 – 14 سال (Assuming fecundity<100).
Fishing Vulnerability (Ref.
59153): Low vulnerability (19 of 100).
