After a long trip on the 3rd of September yesterday we started our activities in the market of Mocajuba. We started by deploying one of the soundtraps (an autonomous recording system) to record dolphins sounds continuously while we observed botos and identified each individually. Later on we decided to test different types of temporary taggings to keep track of all individuals visiting the market on that day, we tried an zinc oxide oitment, lipstick and chopstick. The marks we made were visible, but as dolphins are frequently touching and rubbing against each oother they fade out easily. However we were able to begin a catalog of individuals based on their natural markings, and temporary tagging helps to identify when a new boto comes by.
Today we will try tag deploying for the first time, fieldwork looks promising.
