Estimates based on models
Preferred temperature (Ref. 123201
): 8.5 - 19.5, mean 13.7 °C (based on 29 cells).
Phylogenetic diversity index (Ref. 82804
= 0.6289 [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
): 3.6 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153
): Moderate vulnerability (39 of 100).
