Estimates based on models

Preferred temperature (Ref. 123201): 15.6 - 26.5, mean 23.5 °C (based on 180 cells).

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

Bayesian length-weight: a=0.00295 (0.00131 - 0.00665), b=3.18 (3.00 - 3.36), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.37 se; based on food items.

Generation time: 12.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

लौटाव (Ref. 120179): बहुत नीचे, न्यूनतम जनसंख्या दुगनी समय अवलागत 14 महीने। (tm=9-26; tmax=33).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (79 of 100).

Price category (Ref. 80766): Unknown.
