Feeding habits of Sotalia fluviatilis in the Amazonian Estuary

In this paper we present an analysis of the fifty S.fluviatilis feeding habits in the Amazonian Estuary. Animals were bycaught by the artisanal fishing fleet between 1996 and 2001. Feeding habits were analyzed by prey occurrence frequency (%F) and number percentage and stomachs contents preys simila...
