Estimates based on models
Preferred temperature (Ref. 115969
): 16.1 - 29.3, mean 28 °C (based on 860 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00739 - 0.02049), b=2.92 (2.78 - 3.06), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.3 se; based on size and trophs of closest relatives
Generation time: 0.9 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (11 of 100) .
