“…This is probably because fish stocks have a longer history of commercial exploitation in Europe than crustacean stocks (Ungfors et al . ). Furthermore, assessment methodology differs between the NE Atlantic and the Mediterranean and between different stocks and species.…”

Meta‐analysis of marine biological resources can elucidate general trends and patterns to inform scientists and improve management. Crustacean stocks are indispensable for European and global fisheries; however, studies of their aggregate development have been rare and confined to smaller spatial and temporal scales compared to fish stocks. Here, we study the aggregate development of 63 NE Atlantic and Mediterranean crustacean stocks of six species (Nephrops norvegicus, Pandalus borealis, Parapenaeus longirostris, Aristeus antennatus, Aristaeomorpha foliacea and Squilla mantis) in 1990–2013 using biomass index data from official stock assessments. We implemented a dynamic factor analysis (DFA) to identify common underlying trends in biomass indices and investigate the correlation with the North Atlantic Oscillation (NAO) index. The analysis revealed increasing and decreasing trends in the northern and southern NE Atlantic, respectively, and stable or slowly increasing trends in the Mediterranean, which were not related to NAO. A separate meta‐analysis of the fishing mortality (F) and biomass (B) of 39 analytically assessed crustacean stocks was also carried out to explore their development relative to MSY. NE Atlantic crustacean stocks have been exploited on average close to FMSY and remained well above BMSY in 1995–2013, while Mediterranean stocks have been exploited 2–4 times above FMSY in 2002–2012. Aggregate trends of European crustacean stocks are somewhat opposite to trends of fish stocks, suggesting possible cascading effects. This study highlights the two‐speed fisheries management performance in the northern and southern European seas, despite most stocks being managed in the context of the European Union's Common Fisheries Policy.

“…Besides, it is the IFG stakeholders who have developed the recently approved MP for the key fished stocks relevant to the area, which are currently in the implementation phase. The study area location in the Scottish West Coast inshore fisheries is comprised of single country fisheries, where ample data for many possible indicators useful for the management of the fishery is available (NWIFG Executive Committee, 2011;Scientific Technical and Economic Committee for Fisheries, 2012;The Scottish Government, 2010;Ungfors et al, 2013). The ease of access by the researcher in terms of communication and language, including all the above reasons, make the NWIFG and OHIFG case studies ( Fig.…”

“…This species is exploited on muddy seafloors prevalently by means of bottom trawls and to a lesser extent, in smaller areas (e.g., the northern-eastern Adriatic channels), by means of baited traps (Vrgoč et al, 2004;Ungfors et al, 2013). In the Adriatic Sea, it occurs on muddy (silty-clay) grounds at depths from around 50 m to over 400 m (Artegiani et al, 1979;Wieczorek et al, 1999), with important concentrations occurring around 70 m depth off Ancona, around 220 m depth in the Pomo pit and in the Velebit Channel, Kvarner and Kvarnerić region along the Croatian coast (Karlovac, 1953;Crnković, 1964Crnković, , 1965Froglia and Gramitto, 1981, 1986, 1988IMBC et al, 1994;Froglia et al, 1997).…”

The Saga of the Management of Fisheries in the Adriatic Sea: History, Flaws, Difficulties, and Successes toward the Application of the Common Fisheries Policy in the Mediterranean

In the past 40 years, the fishery in the Mediterranean Sea has seen numerous changes in technology, fleet composition, effort allocation, and management strategies. In this paper, our aim is to summarize the improvements, and highlight the flaws and difficulties that have characterized fisheries management in the Mediterranean Sea in the past decades. We (the authors) advocate the importance of the regionalization of the Common Fisheries Policy (CFP) in the Mediterranean. We focussed on the Adriatic Sea, with two case studies-the fishery for sardine and anchovy, and the fishery for Nephrops. The former is emblematic as it is one of the most valuable and well-studied fisheries in the Mediterranean but it is also an example of a management process that is slowly bearing fruit. Nephrops, on the other hand, has been facing the same destiny as other stocks in the Mediterranean; namely, its peculiar biology, a complex fishery, a poorly tailored data collection and inadequate assessments, have delayed action until very recent times. We use these examples to cover several aspects of Mediterranean fisheries management: (i) a historical overview of the development of these fisheries and their management; (ii) an overview of the main players involved in the scientific analysis and management process and their current and ideal roles; (iii) the flaws of the current stock assessment system; and (iv) recent developments and potential solutions to comply with the latest reform of the CFP before 2020. We argue that to align Mediterranean management with the CFP and achieve MSY targets, the lack of coordination and definition of roles between the General Fisheries Commission for the Mediterranean, the European Commission Directorate-General for Maritime Affairs and Fisheries, the Scientific, Technical and Economic Committee for Fisheries and the Joint Research Centre need to be resolved. There is a need for adequate assessment models and Carpi et al.CFP Application in the Mediterranean data to answer increasingly complex management questions, as well as regular external review of the stock assessment models to assure their quality. Finally, the need for the implementation of a TAC system as an effective tool for Mediterranean fisheries to achieve sustainability is discussed and advocated.
