"Gagata" is a genus of catfishes (order Siluriformes) of the family Sisoridae. It includes seven species, "G. cenia", "G. dolichonema", "G. gagata", "G. itchkeea", "G. melanoptera", "G. pakistanica", and "G. sexualis". "G. gasawyuh" is considered a synonym of "G. gagata" and "G. youssoufi" of "G. sexualis".cite journal|url=http://silurus.acnatsci.org/ACSI/library/biblios/2007_Ferraris_Catfish_Checklist.pdf|title=Checklist of catfishes, recent and fossil (Osteichthyes: Siluriformes), and catalogue of siluriform primary types|first=Carl J., Jr.|last=Ferraris|journal=Zootaxa|volume=1418|pages=1–628|year=2007|format=PDF]

Distribution

"Gagata" species are distributed in the Indus drainage in Pakistan and India, east and south (including peninsular India) to the Tenasserim drainages in Burma. "G. cenia" originates from the Indus, Mahanadi, Ganges, and Brahmaputra drainages in Pakistan, India, Bangladesh, Burma and possibly Nepal; it is also reported from the Irrawaddy drainage and Salween drainage. "G. dolichonema" inhabits the upper Salween River basin in China and the Irrawaddy, Salween, and Tenasserim River basins in Burma. "G. gagata" is from the Ganges drainage in India and Bangladesh and is reported from the Brahmaputra and Irrawaddy drainages. "G. itchkeea" is known from the Narmada, Krishna, and Cauvery drainages in peninsular India, though its presence in the Cauvery needs to be confirmed. "G. melanoptera" is distributed in the Irrawaddy, Rangoon, Sittang, and lower Salween drainages in Burma. "G. pakistanica" is from the Indus drainage in Pakistan. "G. sexualis" originates from the Ganges and Brahmaputra drainages in India, Bangladesh and Nepal.

Description

"Gagata" species have a compressed head, eyes on side of the head, a depressed snout, small conical teeth in lower jaw, branchiostegal membranes broadly fused to isthmus, no serrations on anterior margin of pectoral spine but serrate posteriorly, no well-developed maxillary barbel membrane, outer and inner mental barbels close together with their origins nearly parallel in a transverse line, short nasal and maxillary barbels, and a lack of palatal teeth.cite journal|url=http://www.mapress.com/zootaxa/2006f/zt01345p096.pdf|title=Genera of the Asian Catfish Families Sisoridae and Erethistidae (Teleostei: Siluriformes)|first=Alfred W.|last=Thomson|coauthors=Page, Lawrence M.|journal=Zootaxa|volume=1345|pages=1–96|year=2006|format=PDF]
