Research Topic: The influence of fishing on the trophic structure of fish in Amazonian rivers
Understanding the trophic levels of fish is important to assess the impacts of anthropogenic activities, such as fishing. In recent years, some regions in Amazon are experiencing increased fishing pressure, which can affect important ecosystem services that fish perform. In my Ph.D. I aim to investigate the possible direct effects of artisanal fishing on the trophic structure of fish communities in clearwater rivers (Tapajós, Tocantins, Trombetas) in the Brazilian Amazon through the stable isotope tool combined with fishers’ local ecological knowledge.
