Etymology: Cirrhinus: Latin, cirrus = curl fringe (Ref. 45335).
More on author: Bloch.
The species Cirrhinus mrigala (Hamilton, 1822) is considered as valid in Eschmeyer (CofF ver. May 2011: Ref. 86870) following Menon (1999: Ref. 41236). Please send references, or more studies are needed.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; brackish; benthopelagic; potamodromous (Ref. 51243); depth range 5 - ? m (Ref. 4832). Tropical; 28°N - 7°N
Asia: native to large rivers in the Indian subcontinent (Ref. 12693). Has been so widely transported in connection to aquaculture that its natural distribution can no longer be determined (Ref. 33488).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 100.0 cm SL male/unsexed; (Ref. 33488); common length : 40.0 cm TL male/unsexed; (Ref. 6028); max. published weight: 12.7 kg (Ref. 4832)
Adults inhabit fast flowing streams and rivers (Ref. 41236). Can tolerate high levels of salinity. Juveniles are omnivorous to about 5 cm TL, adults are almost entirely herbivorous. Feed on plankton, but also grazes on algae. Spawning occurs in marginal areas of the water body with a depth of 50-100 cm over a sand or clay substrate. A 6 kg female can lay a million eggs (of 1 mm diameter) (Ref. 6028). Widely cultured in India but fails to breed naturally in ponds, thus induced breeding is done. Fishery harvests 40 cm fish weighing 1000 g and of about 3 years. A very active fish that thrives in ponds but spawns in swift rivers. Fingerlings are in great demand for stocking ponds between July and November (Ref. 4832).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00699 - 0.00990), b=3.04 (2.99 - 3.09), in cm total length, based on LWR estimates for this species (Ref. 93245
Trophic level (Ref. 69278
): 2.4 ±0.17 se; based on food items.
Generation time: 13.1 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.12-0.29).
Fishing Vulnerability (Ref. 59153
): Moderate vulnerability (43 of 100).
Nutrients (Ref. 124155
): Calcium = 188 [86, 396] mg/100g ; Iron = 1.17 [0.53, 2.08] mg/100g ; Protein = 16.7 [15.5, 17.9] % ; Omega3 = 0.38 [0.14, 1.02] g/100g ; Selenium = 203 [72, 545] μg/100g ; VitaminA = 9.7 [3.5, 29.5] μg/100g ; Zinc = 0.808 [0.368, 1.407] mg/100g (wet weight); based on nutrient studies.
