Description

Resource competition between fisheries and marine mammal continue to raise concern worldwide. Understanding this complex conflict requires data on spatial and dietary overlap of marine mammal and fisheries. In Uruguay, the South American sea lions population has been dramatically declining over the past decade. The reasons for this population decline are unknown but may include the following: </br>(1) direct harvesting; </br>(2) reduced prey availability and distribution as a consequence of environmental change; or </br>(3) biological interaction with fisheries. This study aims to determine resource overlap and competition between South American sea lions (SASL, <i>Otaria flavescens</i>, n=10) and the artisanal fisheries (AF), and the coastal bottom trawl fisheries (CBTF).

Data Records
