This is clearly reflected in the statement from World Summit on Sustainable Development (Johannesburg): "MPAs are the key to achieving at least 10% of each of the world's ecological regions effectively conserved - the target established at the 6th Conference of Parties to the Convention on Biodiversity". At the same time, it is widely considered that MPAs can make a significant contribution to regional economic development and to improving the well-being of local communities. Fisheries are one of the main threats to marine biodiversity and ecological processes and MPAs are therefore important for conserving ecosystem services provided by the sea and sustaining tourism that depends on these. By restricting damaging activities, MPAs offer protection for marine natural resources and provide them with critical habitats they need at key times, e.g. for breeding or feeding. MPAs benefit species and habitats of regional interest and may also help to avoid or at least limit the deleterious effects of non-sustainable uses and activities, including pollution and other sources of degradation, in favour of the local economy. However, MPAs, by definition, protect only a defined area and there is a risk that damaging activities may be intensified or inadequately controlled in areas outside the MPA. Establishment of MPAs should therefore be part of a wider strategy for managing marine resources with clearly defined objectives. Effective management of a complex ecosystem under human pressure is not possible without science. The natural sciences are needed to understand the functioning of the ecosystem. MPAs have to be selected, designed, managed and networked in such a way to ensure the maintenance of ecological processes to sustain ecosystem functioning (e.g. connectivity through adult movement and larval dispersal of marine species, habitat representation and replication, preservation of spawning aggregations, recruitment and nursery grounds). Since the first MPA was declared in the Mediterranean, more than 40 years ago (Parc national de Port-Cros, France), a great deal of research has been conducted to describe, characterize and model the ecological effects of protection from fisheries. The EMPAFISH project (European Marine Protected Areas as tools for FISHeries management and conservation), supported by the European Commission, has as general objectives: 1) to investigate the potential of different regimes of MPAs in Europe as measures to protect sensitive and endangered species, habitats and ecosystems from the effects of fishing; 2) to develop quantitative methods to assess the effects of marine protected areas and 3) to provide the EU with a set of integrated measures and policy proposals for the implementation of MPAs as fisheries and ecosystem management tools. The first step to reach these objectives is to know the ecological processes involved in the functioning of a MPA and to understand how ecological networks and relationships between species within an ecosystem reorganize after protection from fishing. From the fisheries point of view, there is an urgent need to know how the behavioural and population responses of individual species and ecological interactions among species may translate into recruitment subsidy and ‘spillover’, which in turn may lead to sustained or enhanced fishery yield in the surrounding region. This cannot be done without well-designed scientific research. Within the EMPAFISH consortium, the 20 case studies included have been the subject of detailed, long-term research. The general objective of EMPAFISH Work Package 1 (WP1: “Ecological effects of Marine Protected Areas”) is to identify and quantify ecological effects of MPAs and to organise the findings in a database for subsequent global meta-analysis and modelling. This booklet constitutes deliverable nº 3 of the EMPAFISH project, under WP1. The present document begins with a brief overview of the ecological processes important for conservation and what are, generally speaking, the expected ecological effects of MPAs. The core of the document is devoted to descriptions of the research done to date at each EMPAFISH case study site to document and understand the ecological effects of protection measures. In chapter 4, a summary of former EC FP5 research project BIOMEX is included; in this project, a consortium of 9 labs (most of them included in EMPAFISH) collected data on 5 out of the 20 cases studies included in EMPAFISH (plus one, Cabrera Archipelago National Park, not included) in order to estimate spillover from MPAs to neighbouring unprotected areas. The majority of these data (using visual census, baited video, ichthyoplankton surveys, and both experimental and onboard commercial fisheries) are to be used within EMPAFISH. Finally, a succinct summary of data available for first analyses within the WP1 is done in chapter 5, including a brief description of new data collected in the framework of EMPAFISH. The bibliography incorporated at the end of this document gives an updated list of articles/references on all ecological studies at the 20 case study sites included in the EMPAFISH project.

  • PESCA ARTIGIANALE SOSTENIBILE NELLE AREE MARINE PROTETTE ITALIANE1 Stato Dell’Arte E Prospettive Future
    PESCA ARTIGIANALE SOSTENIBILE NELLE AREE MARINE PROTETTE ITALIANE1 Stato dell’arte e Prospettive future La direttiva quadro per la strategia marina 2008/56/CE, promuove l’applicazione di un approccio ecosistemico alla gestione delle attività antropiche in mare, per mantenere la pressione di tali attività entro limiti compatibili, ovvero che venga mantenuto nel tempo un buono stato ecologico e che la resilienza dell’ecosistema marino alle perturbazioni antropiche non sia compromessa, consentendo al tempo stesso l’uso sostenibile dei servizi ecosistemici ora e in futuro. Si vuole arrestare la perdita di biodiversità marina, garantendone conservazione e uso sostenibile, grazie all’istituzione di una rete di aree marine protette efficacemente gestite ed ecologicamente rappresentative. La creazione di Siti natura 2000 a mare è stata individuata come primo passo per arrestare la perdita di biodiversità dell’ecosistema marino, nonché per mantenere la sua funzione di fornitore di servizi ecosistemici2. In Italia, come in altri paesi Europei, le AMP (Aree Marine Protette), costituiscono spesso il sistema avanzato di gestione delle aree facenti parte della rete Natura 2000 a mare. Infatti, pur se la politica delle aree protette deriva da leggi e tradizioni diverse da quella della direttiva Habitat, è innegabile la comune finalità. Inoltre i perimetri di molti siti Natura 2000 sono coincidenti o comunque intersecanti con quelli delle aree protette sia terrestri che marine. Nel caso di esistenza di un’area protette anche la gestione del sito natura 2000 trova un soggetto che condivide appieno gli obiettivi e che ha già alle spalle una storia, più o meno lunga di gestione. Quanto è accaduto e sta accadendo all’interno delle aree marine protette su problematiche specifiche quali la pesca, intesa come servizio ecosistemico, è un elemento di conoscenza importante per testare le politiche di conservazione attiva della biodiversità 1.

  • 12 Fishery Reserves in the Mediterranean Sea
    Fishery reserves in the Mediterranean Sea: the Gulf of Castellammare case study ∗ C. Pipitone , F. Badalamenti, G. D’Anna, M. Coppola, G. Di Stefano, G. Scotti Abstract The effects of fisheries management based on artificial reefs and on trawl banning are explored in the Gulf of Castellammare fishery reserve by means of biological (from trammel and trawl survey) data collected during several research programs between 1990 and 2001. The artificial reefs have caused an increase of diversity but not of biomass, as suggested by the comparison between the associated fish assemblage and that of nearby sandy bottoms. The associated species however do not have any trophic relation to the boulders, except the two- banded seabream, Diplodus vulgaris . An overall increase of experimental trammel net yields in the artificial reef area was observed from 1990 to 1998, due mainly to pelagic species associated with the boulders. The trawl ban caused a dramatic increase of groundfish biomass in the protected area (+711% after four years, total species). Different species had different increase rates, from 2-fold for the musky octopus, Eledone moschata to 127-fold for the gurnard, Lepidotrigla cavillone . Eight and ten years after the ban started, the yields did not vary significantly in the overall area, but decreased near to (both outside and inside) the protected area, probably due to increased legal and illegal trawling. The mean size did not increase in three studied species, except for the monkfish, Lophius budegassa . In conclusion the Gulf of Castellammare fishery reserve is considered a positive example of marine coastal fisheries management, especially considering the effects of the trawl ban on the abundance of groundfish stocks, although the cooperation between scientists and administrative bodies is still far from optimal.

  • Additions to the Italian Annotated Bibliography on Bluefin Tuna (Thunnus Thynnus, Linnaeus, 1758) and Comprehensive Overview
    SCRS/2020/057 Collect. Vol. Sci. Pap. ICCAT, 77(2): 226-274 (2020) ADDITIONS TO THE ITALIAN ANNOTATED BIBLIOGRAPHY ON BLUEFIN TUNA (THUNNUS THYNNUS, LINNAEUS, 1758) AND COMPREHENSIVE OVERVIEW Antonio Di Natale1 SUMMARY After the very first attempt to list together the many papers published so far on bluefin tuna (Thunnus thynnus) by Italian scientists, concerning the biology of this species, the fisheries and many other scientific and cultural issues, it was necessary to prepare an addition to the annotated bibliography published in 2019. Therefore, the present paper provides 351 additional papers, all annotated with specific key words, which brings the available papers on this species up to 2100, all duly annotated. This paper also provides an overview of the papers published over the centuries and decades, the main authors and the score of the main topics and themes included in the papers. This updated bibliography was set together to serve the scientists and to help them in finding some rare references that might be useful for their work. RÉSUMÉ Après la première tentative d’établir une liste des nombreux articles publiés à ce jour sur le thon rouge (Thunnus thynnus) par des scientifiques italiens, concernant la biologie de cette espèce, la pêche et bien d'autres questions scientifiques et culturelles, un complément à la bibliographie annotée publiée en 2019 s’est avéré nécessaire. Par conséquent, le présent document fournit 351 articles supplémentaires, tous annotés avec des mots clés spécifiques, ce qui porte à 2100 le nombre d'articles disponibles sur cette espèce, tous dûment annotés. Ce document fournit également un aperçu des articles publiés au cours des siècles et des décennies, les principaux auteurs et la note des principaux sujets et thèmes inclus dans ceux-ci.
