Estimates based on models

Preferred temperature (Ref. 115969): 4.1 - 10.7, mean 6.6 °C (based on 1209 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 1.5000   [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):  3.6   ±0.5 se; based on size and trophs of closest relatives
लौटाव (Ref. 120179):  निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Assuming fecundity<100).
Vulnerability (Ref. 59153):  Very high vulnerability (76 of 100) .
