In the last decades, the human harvesting of marine resources became more efficient as the understanding of the habits and behaviours of the various species available in the sea gradually increased. Technologies naturally developed over time and fishing systems became more sophisticated and increasingly adapted to catch the most desirable species and sizes. This evolution is still in progress and technological development goes on especially in the Mediterranean area, where small and relatively old fishing vessels are traditionally used. These technical advances in fishing gears have generally led to more efficient fishing operations and improved access to resources and fishing grounds. On the other hand, general awareness on the environmental problems due to the exploitation of fisheries resources has also increased. Therefore, in order to preserve fishery resources and marine environments, fishing gears and their impacts need to be further investigated and less impacting techniques should be developed. In this regard, fishing technologists are responsible to provide fishery managers as well as fishermen and stakeholders, with useful advice and technical solutions for mitigating adverse impacts of fishing gears. By taking these problems into account, the book contents are based on the requirements of ecosystem-approach to fisheries management. The Code of Conduct for Responsible Fisheries of the FAO (1995) encouraged the use of selective, environmentally safe and cost effective gear and techniques. Thus the book aims at providing information on sustainable fishing technologies, and transfers the expertise on fishing technology to Mediterranean fisheries scientists and end-users such as fisheries managers, administrators, controllers etc. This book is structured to provide information on fishing gear technology, selectivity, bycatch-impact reduction and fishing vessel technology, with particular attention to the Mediterranean context. The information included might be used to learn how to assess the impacts and selectivity of different fishing gears and find technical solutions to mitigate these impacts and to address scientific studies. Furthermore, advices on the properties of fishing vessels affecting energy efficiency have been also considered in order to address possible technical changes to the currents boats. Finally the contents of this book might be considered as a useful tool when preparing management measures as well as for the establishment, enforcement or improvement of fishing rules.
