Description 948-954
A total of ten different marine/brackish water fish species was recorded at Tribeni, a completely freshwater region
located 212 km upstream from the sea in Hooghly estuary just after tidal bore, a natural high wave and high flow regime
created during the spring tide around full moon/new moon days. A range of 85 – 179 km upstream shift of recorded marine
fish species from their normal distribution range may be attributed to high turbulence, flow, and wave associated with bore
tide as there is no sign of saltwater ingress in the Tribeni area as revealed through the analysis of associated environmental
parameters. In addition to salinity, such extreme climatic events like tidal bore should also be considered to explain the fish
species distribution in a tidal estuary
