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.
