Abstract
The workshop on Aquaculture engineering and offshore culture, organised on June 23–25, 1993, with the collaboration of IFREMER, was gathered around the theme “Open sea aquaculture”.
Conditions of development of mussel, sea bass and sea bream aquaculture in open sea in the Mediterranean have been presented and discussed. Three aquaculture sites have been visited. Those three sites illustrated graduation of expositions from sheltered bay to open sea.
Open sea exposition became a growing need for increasing space resources as well as for escaping coastal environment degradations. It is unaviodable for certain countries like Cyprus, Malta and Portugal because of rarity if not absence of sheltered sites. In the case of Malta, three open sea aquaculture farms are operating. As no anterior aquaculture know-how exist on the island, which could be used as footboard, this a consequent “jump in the darkness”
Other aspects than technological have been examined, especially risk management in aquaculture, its coverage by insurance, and the environmental constrains related to the activity.

The Editor would like to thank the French Government, IFREMER, namely Mr. Philippe Ferlin, the National Coordinator for his support to the organisation of this activity. Thanks are also addressed to the participants from the Member/Associated countries who accepted to contribute to the seminar.
Note from the reviser
The revision and publication of this document could only be done a long time after the closure of the project. This has led to some difficulties in finalising the documents and implementing corrections, because authors and contributors as well as some of the original material or files were no longer available.
Therefore contributions from participants and session papers annexed to most of the documents were left in their original from. No language corrections were introduced, the content was not modified and left under their respective authors' responsibility.
Considering the above, we hope that the reader will understand that a standard of publication could not be maintained on a level as high as we would have liked it to be.
