Estimates based on models

Preferred temperature (Ref. 115969): 24.5 - 29, mean 27.5 (based on 294 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.00 (2.82 - 3.18), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.0 ±0.00 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (tm=4; K=0.428; Tmax=25).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (33 of 100).
