Phylogenetic diversity index (Ref. 82804
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00759 (0.00597 - 0.00963), b=2.91 (2.84 - 2.98), in cm total length, based on LWR estimates for this species (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.53 se; based on food items.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.23, assuming Fec > 10,000).
Fishing Vulnerability (Ref. 59153
): Very high vulnerability (90 of 100).
