Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01514 (0.00660 - 0.03472), b=2.99 (2.79 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.39 se; based on food items.

Generation time: 6.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Daya lenting (Ref. 120179): sedang, Waktu penggandaan populasi minimum 1.4 - 4.4 tahun (K=0.17).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (48 of 100).

kategori harga (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 84.4 [45.8, 169.8] mg/100g; Iron = 1.3 [0.8, 2.2] mg/100g; Protein = 17.2 [16.1, 18.2] %; Omega3 = 0.397 [0.156, 1.003] g/100g; Selenium = 70.8 [31.9, 148.7] μg/100g; VitaminA = 28.2 [10.2, 70.6] μg/100g; Zinc = 1.45 [0.97, 2.05] mg/100g (wet weight);
