Estimates based on models
Preferred temperature (Ref. 123201
): 13.2 - 23.4, mean 19.2 °C (based on 97 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00649 - 0.02558), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 4.0 ±0.66 se; based on food items.
Generation time: 7.0 ( 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.).
Fishing Vulnerability (Ref. 59153
): Moderate to high vulnerability (54 of 100).
