The 1st ever dolphin census of the Marañon and Huallaga rivers in Peru reveals a thriving population.

An expedition carried out by World Wildlife Fund – Peru (WWF Peru) and Pro Delphinus successfully completed the 1st ever dolphin census of the Marañon and Huallaga rivers of Peru, two major tributaries of the Amazon river.

The expedition, which lasted 3 days and covered over 300 kilometers, revealed a rich population of the 2 dolphin species that are native to Peru.  One of these species is the well known pink dolphin (Inia geoffrensis) and the other is the gray dolphin (Sotalia fluviatilis), according to Andina.

However, not all is well, WWF Peru tells us.  Both species are at risk due to hydroelectric power projects in the region, which would disrupt migration patterns, while the pink dolphin is particularly under threat from local populations because they are used for fishing bait.

Andina also informs that the census results are to be published in the following days.
