Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278): 4.0 ±0.5 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 (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (54 of 100).
