Dear all,
I am an Italian marine biology researcher. 
I am interested in studying the Indian humpback dolphin (Sousa plumbea) population inhabiting the waters off Zanzibar Arcipelago, Tanzania.
I think it would be necessary to monitor these cetaceans and their inshore distribution that renders them particularly susceptible to the effects of human activities in the coastal zones.
On this purpose, I would like to run a project studying their behavioural ecology and reactions towards vessel activity, making a comparison between Unguja and Pemba Island.
In fact, on Unguja Island there’s a lot of disturbance caused by human activities, while in Pemba these anthropogenic factors seem to be really rare.
Thus, I would like if anyone has some articles about the situation of humpback dolphins in this area, that can be really useful for my project.
These are the articles that I have already found:
