Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; pelagic-neritic; amphidromous (Ref. 51243); depth range 0 - 50 m (Ref. 189). Tropical; 26°N - 7°N, 76°E - 99°E (Ref. 189)
Indian Ocean: eastern coasts and estuaries of India, and also Irrawaddy River at Rangoon, Myanmar. All Indian references to a species with over 7 pectoral filaments must apply to Coilia reynaldi.

Morphology | Morphometrics
soft rays: 80. Body tapering, belly rounded before pelvic fins, with 6 to 9 + 7 to 11 = 13 to 19 keeled scutes from just behind pectoral fin base to anus. Maxilla short, not reaching to edge of gill cover. Pectoral fin with 10 to 13 long filaments; the branched fin rays much shorter those of pelvic fin.
Occurs in coastal and tidal stretches of rivers, but apparently no data on salinity tolerances. Its presence above Barrackpore on the Hooghly in India suggests that it can live in freshwater. Larvae feed on copepods; thereafter mainly on copepods, but also on prawns, larval decapods and other crustaceans. Breeds in the lower parts of estuaries. The time and duration of the breeding season reported vary for different estuaries in India.

Bayesian length-weight: a=0.00282 (0.00125 - 0.00638), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.46 se; based on food items.
Generation time: 1.6 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (K=0.7).
