Estimates based on models

Preferred temperature (Ref. 123201): 17.5 - 23.5, mean 19.7 °C (based on 31 cells).

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

Bayesian length-weight: a=0.00479 (0.00196 - 0.01170), b=3.16 (2.95 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.2 se; based on size and trophs of closest relatives

Generation time: 2.4 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec < 1,000).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
