Abstract
Aquaculture and fisheries are essential resources for the agri-food
production of the north Adriatic coast. In particular mussels farms occupy a
large area of the gulf of Trieste. A total of 16 producers, working in small
cooperatives or individually, utilize 30 vessels on the 15 km of mussels
long-line along the coast. Our study intends to analyze and evaluate the
sustainability of this activity also in relation to its productivity, and to
contribute to development of a tool for the optimization of ecological
sustainability of mussel production. The analysis of sustainability is done
with the application of two different indexes: Ecological Footprint and
Emergy Analysis. Emergy Analysis entails comparison of this activity with
other types of aquaculture (or agriculture), which utilize different methods
to obtain the same final production. The computation of Ecological
Footprint, an index seldomly apply to marine systems, will highlith the
dependency of mussels aquaculture in the Gulf of Trieste from other local
or national resources. The evaluation is based on a data set obtained trough
interviews and questionnaires submitted to the producers, which intended
to evaluate the materials, technologies, methods of production, and
commercial channels, and an official informations from local authorities
Production data have been submitted by public structures and sales
cooperatives (producers).Keywords: Fisheries Economics, Modeling and Economic Theory, Integrated Modeling Approach of Social and Environmental Interactions in Support of Marine Resource ManagementKeywords: Fisheries Economics, Modeling and Economic Theory, Integrated Modeling Approach of Social and Environmental Interactions in Support of Marine Resource Managemen
