Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 24 - 26; Mjukstrålar i ryggfenan (totalt) : 30 - 42; Mjukstrålar i analfenan: 31 - 46.

Inhabits slow and shallow waters of rivers of plains and estuaries; never available above an altitude of 366 m. Also found in canals, streams, beels, ponds and inundated fields (Ref. 1479). Has been placed into aquaria and kept by hobbyists; it stays on the bottom and spawns in the upper water-level. The more slender and generally smaller males pursue the female in courtship; several males may join in.

Estimates based on models

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

Bayesian length-weight: a=0.00407 (0.00318 - 0.00521), b=3.02 (2.96 - 3.08), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.5 ±0.51 se; based on food items.

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (K=1.0-1.7).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Price category (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 354 [225, 712] mg/100g; Iron = 2.41 [1.44, 4.14] mg/100g; Protein = 17.6 [16.2, 18.9] %; Omega3 = 0.173 [0.085, 0.348] g/100g; Selenium = 52.6 [24.3, 111.0] μg/100g; VitaminA = 31.9 [13.8, 72.4] μg/100g; Zinc = 1.43 [1.06, 1.97] mg/100g (wet weight); based on nutrient studies.
