Freshwater ecosystem degradation in the Turag River basin is increasing due to rising human settlement, reduced water flow during the dry season, new large land development projects, and toxic emissions caused by brick kilns. The population of river dolphins was estimated through surveys carried out from December 2012 to November 2013. Surveys were conducted on a fortnightly basis. The dolphins were counted within an 18.4 km stretch (known to be the most polluted stretch) of the 75 km long river. A total of 62 dolphin sightings were recorded, both as individual sightings and as groups. The highest monthly count was in August. The besthigh-low estimates of 9-11-7 individuals were recorded in August 2013 in river ecology. Seasonal changes in spatial distribution were observed. The survey revealed that rising floodwater stimulated an increase in the dolphin population in the study area from July to October. The maximum encounter rate was also 0.49 sightings km −1 for the month of August. The sightings and encounter rates of dolphins were lower from December to July (dry and premonsoon period) likely due to reduced water flow and adverse water quality of this river.

The aquatic mammalian species is the best indicator for the health of water specially dolphins. Due to human anthropogenic activities, dolphin survival rate and movement are reduced. The dreadful conditions of coastal habitats can have major concerns for dolphin population and distribution. Some dolphins swim in a short distance and some swim in a long distance. Southeast Asia is a significant geographical region for dolphin conservation. Several dolphins are highly important for the maritime area of Bangladesh that were sighted in the coastal and marine water such as Irrawaddy dolphin, Indo-Pacific Humpback dolphin, Bottlenose dolphin, Spotted dolphin, Spinner dolphin, and Ganges dolphins. Marine protected area (MPA) is a valuable zone for dolphin conservation as well as biological species. This primary information of dolphins helps for further investigation in the Bangladeshi water. The research action plan must be considered with coastal habitat, marine protected area and fishing community to conserve dolphins. We should be concerned about dolphin conservation through local and international community to develop the environment and the blue economy. Local community directly involved in the maritime area due to livelihood opportunities.
