| Abstract |
- Mussels aquaculture is a relevant activity for the fishery sector of the North
Adriatic. Around 15 km of coastal water of the Gulf of Trieste, Italy, are
used for the mussel long line farming, for a production of about 5000
tonn/year. The aim of this work is to assess sustainability of this activity in
a Ecological-Socio-Economical (ESE) perspective by evaluating the role of
mussels farming in the socio economic system and in the ecological
system. A socio economic analysis has been conducted involving local
stakeholders in meetings, and also by contacting them with bilateral
interviews and questionnaires. Results of questionners, together with
mussels production data declared at the Sanitary authority, and official
economic data, have been used to quantify the economic relevance of the
activity, and problems perceived by local farmers. For the ecological
analysis, we monitored -on monthly basis- mussels growth and water
quality parameters in 6 sites along the gulf. Feeding preference and
faeces/pseudofaeces production, impact on surface sediment ad its
reversibility have been investigated, too. Results have been used to
calibrate a bioenergetic model representing the mussel physiology and
growth in relation to environmental conditions, and the impact of mussel
aquaculture on water column. The integration of the whole set of models
and information will be used to give an evaluation of the ecological
footprint of the activity and as a tool for coastal management.
