The Pacific Ocean off of Ecuador encompasses important habitats for 27 marine mammal species and the Amazon basin is home to otters, manatees, and 2 species of dolphin. Since 1996, Nazca Institute researchers, in cooperation with foreign NGO's such as Yaqu Pacha, have been studying the population biology, behaviour and conservation issues regarding the marine and aquatic mammals of Ecuador.
The Ecuadorian coastal habitats, especially in the provinces of Manabí and Esmeraldas, are preferred breeding grounds of the South Eastern Pacific Humpback whale population. From June to October, we have accompanied the whales every year since 1996 to monitor population size, distribution and the impact of whale watching tourism on their natural behaviour. Since 2000 have worked in close cooperation with fishermen in Esmeraldas, combining whale watching with our normal research activities.
