Cauvery river system is one of the major freshwater aquatic systems in Peninsular India with a number of tributaries and reservoirs on it. The system inhabits a variety of endemic fish species. Thippagondanahalli Reservoir (TR) is a medium reservoir on Arkavathy River, a tributary of River Cauvery. This report is on the first record of dwarf gourami, Trichogaster lalius belonging to the family, Osphronemidae, from the TR. The reservoir is located in Bengaluru South Taluk, Karnataka [13â°02’41”N 77â°36’24”E; Area at FRL (Full Reservoir level): 1162.0 ha]. A total of nine specimens of the species were collected from the reservoir during various seasons (pre-monsoon, monsoon, post-monsoon) in 2015-16. It is a species having high value in the ornamental fish industry and a great demand in international market. Population study and proper management practices will help to improve the population of the species; will add on fisherman income and improve their livelihood. Further studies are required to find the parent population of T. lalius. The introduction of T. lalius in TR may be accidental and the macrophytes in the reservoir being suitable for the inhabitation of the species would have supported in establishing the population.
