Estimates based on models

Preferred temperature (Ref. 115969): 12.5 - 27.6, mean 18.2 (based on 576 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00741 (0.00645 - 0.00852), b=3.03 (2.99 - 3.07), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.49 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (K=0.38-0.47).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (31 of 100).

Price category (Ref. 80766): Very high.
