Estimates based on models

Preferred temperature (Ref. 123201): 10.1 - 18.6, mean 13.7 °C (based on 68 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00282 (0.00133 - 0.00596), b=3.25 (3.08 - 3.42), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.6 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): High to very high vulnerability (74 of 100).
