Influence of environmental and operational variables in commercial fishery landings: The case of pair trawlers in southeastern Brazil
Faced with the overexploitation reality of many of the world fish stocks and climate change, understanding the relationships between catches, fishing strategies and environmental conditions becomes crucial. In this context, this study aimed to describe the correlations between operational and enviro...
