Estimates based on models
Preferred temperature (Ref. 115969
): 26.9 - 29.1, mean 28.4 °C (based on 526 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00515 - 0.02940), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.4 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).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
