Book (series)Practical Guidelines for the Use of Artificial Reefs in the Mediterranean and the Black Sea
Studies and Reviews. General Fisheries Commission for the Mediterranean
2015Also available in:
No results found.Artificial reefs have been used for a long time around the world and have served many purposes ranging from habitat restoration, fish stock enhancement and fisheries management to research and recreation. At present, fish stock enhancement and fisheries management are the main reasons driving reef construction in the Mediterranean Sea, while habitat restoration is the main purpose for their use in the Black Sea. The increasing interest for artificial reefs has given rise to several concerns rega rding their possible negative impacts, due to the use of unsuitable materials and to waste dumping. Consequently, the need emerged over the past fifteen years to develop guidelines in order to support managers and scientists in the use of artificial reefs in European seas. Based on such existing guidelines, this document aims to further provide up‐to‐date information and guidance regarding specific management practices for the planning, siting, construction and anchoring of artificial reefs in t he Mediterranean and the Black Sea and for monitoring their effectiveness from an ecological and socio‐economic point of view. After providing an overview of existing definitions and legislations relating to the deployment of artificial reefs, this document illustrates the main aspects related to the different steps involved in the planning, siting and construction phases. A detailed presentation of the specific types and purposes of artificial reefs follows, with a description of their possible impacts and of existing methodologies to monitor and assess their effectiveness. Finally, these guidelines give insights about the socio‐economic effects of artificial reefs and control, surveillance and maintenance issues. -

Book (stand-alone)Technical guidelines for scientific surveys in the Mediterranean and the Black Sea
Procedures and sampling for demersal (bottom and beam) trawl surveys and pelagic acoustic surveys
2020Also available in:
No results found.In the Mediterranean and the Black Sea, the assessment of demersal stocks mainly relies on scientific surveys (bottom and beam trawl) while the assessment of pelagic stocks is essentially based on acoustic surveys using acoustic techniques with mid-water trawling. These routine surveys-at-sea provide essential information, which in turn are crucial to fine-tune the assessments of the status of resources and to estimate more precisely indicators at the population and fish community levels. However, survey practices differ from one subregion to another, each approach having its own strengths and limitations. In addition, there is still a lack of large-scale standardized surveys aimed at analysing the diversity and distribution of the main demersal and pelagic species across the Mediterranean and the Black Sea. One way of tackling this issue is to carry out international scientific surveys covering the main demersal and pelagic stocks based on a common methodology. The methodology presented in this publication aims at supporting the planning and implementation of regional demersal (bottom and beam) trawl and pelagic acoustic surveys. It can be useful for the implementation of new surveys-at-sea in areas where demersal trawl and pelagic acoustic surveys are not regularly carried out. It can also contribute to increasing comparability between existing surveys thanks to the standardization of methods, sampling of catches and data recording and analysis. Finally, it represents a valuable tool to define minimum requirements towards sustainability and management objectives at the regional and subregional level.
