The Gangetic River Dolphin Platanista gangetica is an endangered species and this species has also been included under Appendix I of CITES. This study was based on direct count method by raft survey and multiplatform survey. In addition, questionnaire survey was also conducted with locals and fishermen of the study area to know their perceptions on dolphin. The water quality of the sites, where dolphin were seen, was analyzed using standard methods. Two dolphins were observed in the upper section of the Koshi Barrage and this is a very low number that could extinct in very future if no conservation measures are taken. Also, a rare sighting of the species has been reported by locals near irrigation canals and small tributaries of the Koshi River. Survey carried out below the Koshi Barrage revealed only four dolphins. According to local people, 10 to 15 dolphins used to appear in this section but because of change in the course by Koshi River due to the outburst of Koshi Dam, there was a low water level to support the dolphin habitat, so they might have migrated to the Ganges in India. The water quality of Koshi at the site of dolphins occurrence was determined to be normal. Accidental trapping and killing of dolphin with the use of fishing nets are identified as major threat. Various human activities like fishing, washing, transporting forest products, establishment of the ferry, construction of irrigation canals, high dams etc. ....

The Meghna River is one of the most important rivers in Bangladesh, one of the three rivers, the Ganges delta, and the largest delta in the world in the Bay of Bengal. The water quality of Meghna has become a matter of concern due to serious levels of pollution. The present study was conducted to assess the surface water quality of upstream of the Meghna River using physic-chemical parameters in summer and winter season at five different points. Water quality was evaluated by laboratory analysis considering a total of six water quality parameters, pH, DO, BOD, COD, salinity and TDS and water samples were collected from five stations. The study indicates that some parameters exceed the permissible limit for drinking purpose, it may cause potential threat to the human, but the water of this river is not immediate threat to human or ecosystem.
