Estimates based on models
Preferred temperature (Ref. 123201
): 19.7 - 27.9, mean 25.6 °C (based on 394 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02344 (0.01045 - 0.05258), b=2.88 (2.71 - 3.05), in cm total length, based on LWR estimates for this Genus-BS (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
