Estimates based on models
Preferred temperature (Ref. 115969
): 25.2 - 29.3, mean 28.5 °C (based on 3110 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01349 (0.00861 - 0.02115), b=2.98 (2.85 - 3.11), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 2.0 ±0.00 se; based on food items.
Generation time: 6.5 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (51 of 100) .
