FISH BIODIVERSITY OF NARMADA IN SUBMERGENCE AREA OF INDIRA SAGAR RESERVOIR
552 / 0
Abstract
The present study has been conducted to assess the spatial and temporal variation of fish fauna in the stretch of Indira Sagar submergence area. This paper attempts to document the fish biodiversity of Indira sagar reservoir submergence area and tributaries of river Narmada viz., Ganjal and Machak, temporal variation therein and also assess the impact of formation of reservoir on the riverine fish fauna. During the study fifty two species belonging to 28 Genera, 13 Families and 7 Orders were encountered. Twenty species were recorded in Machak River whereas twenty nine species were
recorded in Ganjal River, nineteen species were recorded in Narmada River near Nemavar village and thirteen species were reported at the tail end of the reservoir near Purni. The study indicates that this region is still a hotspot of fish biodiversity and conservation measures should be followed to sustain fish biodiversity of tributaries.
Key words : Biodiversity, reservoir, river Narmada.
