Estimates based on models

Preferred temperature (Ref. 123201): 7.8 - 13.4, mean 10.8 °C (based on 55 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00562 (0.00288 - 0.01097), b=3.11 (2.94 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.7 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (50 of 100).

Nutrients (Ref. 124155): Calcium = 8.03 [1.46, 39.68] mg/100g; Iron = 0.318 [0.074, 0.996] mg/100g; Protein = 16.4 [13.6, 18.8] %; Omega3 = 0.538 [0.174, 2.078] g/100g; Selenium = 13 [4, 41] μg/100g; VitaminA = 9.9 [2.3, 43.2] μg/100g; Zinc = 0.325 [0.163, 0.604] mg/100g (wet weight);
