Estimates based on models

Preferred temperature (Ref. 123201): 20.6 - 27.7, mean 23.3 °C (based on 42 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01413 (0.00578 - 0.03452), b=3.07 (2.86 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.47 se; based on food items.

लौटाव (Ref. 120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Assuming fecundity<100).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (43 of 100).

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 24.6 [3.3, 473.3] mg/100g; Iron = 0.734 [0.067, 8.603] mg/100g; Protein = 19.3 [14.1, 24.6] %; Omega3 = 0.137 [0.042, 0.426] g/100g; Selenium = 43.3 [7.9, 211.2] μg/100g; VitaminA = 14.9 [1.0, 174.9] μg/100g; Zinc = 1.04 [0.07, 12.42] mg/100g (wet weight);
