Estimates based on models
Preferred temperature (Ref. 123201
): 26.1 - 27.2, mean 26.4 °C (based on 12 cells).
Phylogenetic diversity index (Ref. 82804
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00555 - 0.02485), b=2.96 (2.79 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.3 ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Assuming Fec > 10,000).
Fishing Vulnerability (Ref. 59153
): Moderate to high vulnerability (50 of 100).
