Estimates based on models
Preferred temperature (Ref. 123201
): 25.3 - 28.9, mean 27.7 °C (based on 556 cells).
Phylogenetic diversity index (Ref. 82804
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00174 - 0.01147), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this Subfamily-BS (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Assuming Fec < 100).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
