Estimates based on models
Preferred temperature (Ref. 123201): 9.8 - 14, mean 11.7 °C (based on 15 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 4.1 ±0.6 se; based on size and trophs of closest relatives
लौटाव (Ref. 120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).
