Book Description
This workshop stressed that the concept of reference points (RPs) needs to be closely connected to the management objective of concerned fisheries, taking into account various parameters such as maximum sustainable yield, economic and social benchmark and environment concern. Participants stressed the need to define different RPs for each dimension of management or to identify a single RP aimed at ensuring the sustainability of the system, thereby no longer limited to biological aspects. A review of possible approaches to setting RPs and indicators for Black Sea fisheries emphasized the dynamic nature of recent ecosystem changes. The traffic light approach was illustrated as a means of following dynamic changes and gaining a broad perspective on events at the ecosystem level. The workshop outlined the main RPs obtained by applying the bio-economic optimization models of effort and effort-catch as derived from the theory of population dynamics.

Book Description
This document draws the picture of the existing market of meagre and describes the possible routes for development. Meagre culture started in France and in Italy in the late '90s and is developing in the Mediterranean Region, jumping from a few tonnes in 2 000 to over 10 000 tonnes expected in 2010, highlighting the appearance of a new aquaculture species on the market. Indeed, based on its aquaculture characteristics, meagre has the potential to become a mass market species, moving from the present position of a niche species with a limited production directed to selected market segments. The paper recommends some actions to be undertaken to consolidate good conditions for future growth and to reduce commercial risks.

Book Description
The aim of this paper is to analyse the trade in fish and fishery products in the Mediterranean basin. With reference to the fisheries sector, it appears that the influence of market forces on the management of fisheries (and vice-versa) is increasing. After an overview of recent trends in fishery production, the study focuses on the exchange of fishery products, based on data from UN-Comtrade and FAO and Eurostat data. The core of the study comprises an analysis of the fish trade between the two sides of the Mediterranean basin, the EU and the non-EU countries. At the European level, the trade in fish products between the northern and the southern Mediterranean is of particular importance when considering recent in production and consumption, as well as the legal framework covering both the production and trade sides of the fishery sector. The cross-sectoral analysis of fishery production and trade provides a number of conclusions and lessons for the future of fishery management.

Book Description
"The document "Indicators for the sustainable development of finfish Mediterranean aquaculture: highlights from the InDAM Project" reports the activities carried out during the first year of the InDAM Project "Indicators for Sustainable Development of Aquaculture and Guidelines for their use in the Mediterranean", in support to the GFCM CAQ Working Group on Sustainability in Aquaculture (WGSA). The project focuses on the practical use of the indicators for sustainable aquaculture and their adaptation to the Mediterranean Region. The methodology applied for the identification of the preliminary list of indicators was based on the PCI (Principles, Criteria and Indicators) approach and took into consideration the main outcomes and achievements of the recent projects carried out in the Mediterranean on the identification of indicators for sustainable aquaculture. The document also reports the results of the workshop on the "Selection of indicators for the sustainable development of aquaculture in the Mediterranean Sea" (27-28 November 2008, Montpellier, France), the expert meeting on "Indicators for the sustainable development of aquaculture in the Mediterranean Sea" (24-26 February 2009, Montpellier, France) and the workshop on "Guidelines and application of indicators for sustainable development of aquaculture" (19-20 November 2009, Salammbô, Tunisia), with recommendations given by the WGSA. The two pilot studies on the selection and evaluation of the indicators for aquaculture sustainable development carried out in Mugla, Turkey, and Monastir, Tunisia, are described. The report also includes a series of documents gathered and produced by the experts involved in InDAM activities."--P. [4] of cover.
