Estimates based on models

Preferred temperature (Ref. 123201): 24.5 - 28.9, mean 27.7 °C (based on 706 cells).

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

Bayesian length-weight: a=0.02512 (0.01442 - 0.04376), b=3.00 (2.85 - 3.15), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.0 ±0.00 se; based on food items.

लौटाव (Ref. 120179): माध्यम, न्यूनतम जनसंख्या दुगनी होने का समय 1.4 - 4.4 वर्ष। (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (49 of 100).
