Asia: Indus, Ganges-Brahmaputra and Mahanadi river basins in India. No valid records from Irrawaddy, Salween or other river basins of Myanmar. Reports of Chitala chitala from Thailand and Indo-China were based on Chitala ornata and those from Malaysia and Indonesia on Chitala lopis.

Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 0; Rückenflossenweichstrahlen (insgesamt): 9; Afterflossenstacheln 0; Afterflossenweichstrahlen: 117 - 127. The only species in which subadults and adults have a series of transverse gold or silver bars on the dorsum, but this color feature is not always present (Ref. 7431). Differs from C. ornata in never having ocellated spots and from C. blanci and C. lopis in never having a black spot on the pectoral fin base (Ref. 7431).

Facultative air-breathing (Ref. 126274); Adults inhabit freshwater rivers, lakes, beels, nullahs in the plains (Ref. 41236), reservoirs, canals and ponds (Ref. 1479). Feed on aquatic insects, mollusks, shrimps and small fishes (Ref. 1479). Females lay eggs usually on stake or stump of wood, males fan them with tail, keep them aerated and silt-free, guard them against small catfish and other predators; complete give-away to fishermen; females not observed at egg posts; moderately important food fish (Ref. 2686). Spawn once a year during May to August (Ref. 6459).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5166 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01259 (0.00522 - 0.03035), b=3.05 (2.83 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.59 se; based on food items.

Generation time: 3.7 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (tm=2).

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

Preiskategorie (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 72.1 [24.2, 211.9] mg/100g; Iron = 1.51 [0.55, 3.74] mg/100g; Protein = 17.4 [15.7, 19.1] %; Omega3 = 0.358 [0.132, 0.991] g/100g; Selenium = 104 [32, 279] μg/100g; VitaminA = 17.1 [3.8, 70.3] μg/100g; Zinc = 0.686 [0.386, 1.490] mg/100g (wet weight); based on nutrient studies.
