Tunas off northwest Africa: The epipelagic diet of The Bigeye and Skipjack tunas [PDF]

Fisheries Research, 2021
Abstract Tunas are among the most exploited top predators worldwide, with negative impacts on some of their stocks. Changes in their population abundance can impact marine food-webs and have the potential to alter entire ecosystems. To better understand the impacts of the exploitation of tuna stocks in the most critical habitats, basic knowledge on ...
