Ecology and management of small-scale benthic fisheriesthe stalked barnacle in europe

Resumo

Despite the undeniable importance of small-scale benthic fisheries (also known as S-fisheries) the approaches used in their management fail to incorporate the spatial heterogeneity of their targeted stocks. This has led to important depletions of S-fisheries worldwide. Taking the European stalked barnacle fisheries as the case study, the aims of this thesis are to increase the understanding of the large-scale biological heterogeneity of benthic stocks and explore models that increase the sustainability of the S-fisheries targeting them. The thesis counts with three objectives: 1) The development of a general governance model that promotes the social, ecological and economical sustainability of S-fisheries, 2) the understanding of the large-scale reproduction and recruitment dynamics of a coastal benthic stock and 3) the assessment of spatial management tools like rotational harvest in S-fisheries. The lessons derived from this thesis contribute to the Sustainable Development Goals (SDGs) of the 2030 Agenda of the United Nations (particularly SDG 14: Life below water) through policy recommendations that increase the long-term sustainability of S-fisheries from a broad social-ecological perspective.
