Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01698 (0.00799 - 0.03608), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for species & Subfamily-BS (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (25 of 100).
