Estimates based on models

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

Bayesian length-weight: a=0.00513 (0.00255 - 0.01032), b=3.13 (2.94 - 3.32), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.45 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Fec=16,500 (landlocked population)).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (28 of 100).
