Estimates based on models

Preferred temperature (Ref. 115969): 13.1 - 25.4, mean 23.7 (based on 68 cells).

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

Bayesian length-weight: a=0.02138 (0.01284 - 0.03560), b=2.99 (2.85 - 3.13), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.45 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (tm=2).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (37 of 100).

Climate Vulnerability (Ref. 125649): Very high vulnerability (81 of 100).
