PREPARATION OF THIS DOCUMENT This publication has been prepared within the project “LaMed – Strengthening cooperation on fisheries and aquaculture management in the Mediterranean and the Black Sea” implemented by the General Fisheries Commission for the Mediterranean (GFCM) in 2011–2012 and funded by the Directorate General for Fisheries and Aquaculture of the Italian Ministry of Agricultural, Food and Forestry Policies (MiPAAF). The LaMed project was divided into two components: • Component 1. Fisheries laws and regulations in the Mediterranean and the Black Sea • Component 2. Mediterranean coastal lagoons management: interactions between aquaculture and capture fisheries In particular, component 2 was designed and developed within the overall context of integrated coastal zone management (ICZM) and ecosystem approach from an aquaculture perspective. The main objective of this component was to explore issues related to the sustainable use of coastal lagoons in the Mediterranean area, taking into consideration the ecological features and intrinsic fragility of lagoon ecosystems and the variety of management strategies applied in different countries and at different times. The goal was to gather elements for the development of a sustainable management strategy, also through the preparation of guidelines to be translated in a Mediterranean action plan for coastal lagoons management, within the framework of the GFCM objectives and mandate. This document represents the main outcome of the project and offers a comprehensive – although not exhaustive – review aimed at providing background information and technical support to administrators, managers and decision-makers. ACKNOWLEDGEMENTS This document is the fruit of team work; it could not have been completed without the cooperation and contribution of the national experts from the Mediterranean region.

Mediterranean coastal lagoons: sustainable management and interactions among aquaculture, capture fisheries and the environment Studies and Reviews. General Fisheries Commission for the Mediterranean. No 95. Rome, FAO. 2015. 278 pp. ABSTRACT The Mediterranean region hosts around 400 coastal lagoons, covering a surface of over 641 000 ha differing in both their typology and use. Fisheries and various forms of aquaculture have been traditionally carried out in Mediterranean coastal lagoons since ancient times and are part of the cultural heritage of the region. Traditional lagoon management linked to extensive aquaculture and fish harvesting has certainly contributed, over time, to preserve these peculiar ecosystems, although much of the coastal lagoon areas have progressively disappeared due to land reclamation and other uses. Recently, coastal lagoons have become a relevant environmental concern: land claiming, pollution and the lack of management, among other factors, have strongly modified both the structure and functioning of these sensitive coastal ecosystems. In particular, the management of traditional aquaculture and capture fisheries activities has been identified as the main instrument to maintain lagoons’ ecological features and to prevent the degradation of their sensitive habitats, both from an environmental and socioeconomic point of view. To guarantee the sustainability of aquaculture and capture fisheries in lagoons, proper management plans should be established so as to ensure the preservation of both biodiversity and local knowledge. This should also be considered as a fundamental pillar for any programme aiming at the preservation and restoration of lagoons’ environment. This volume is divided into three main sections. The first part of the document (Part 1) gives an overview of the general context, with particular reference to the LaMed project carried out within the activities of the GFCM Committee on Aquaculture (CAQ) and to the main conclusions of an ad hoc expert meeting held in 2011, and presents a review of Mediterranean coastal lagoons summarizing the information obtained from literature and from country reports compiled within the project activities. In the second part (Part 2), eleven country reports collected from Albania, Algeria, Egypt, France, Greece, Italy, Montenegro, Morocco, Spain, Tunisia and Turkey are fully presented and offer an updated review of the state of Mediterranean coastal lagoons and of interactions among aquaculture, capture fisheries and the environment. Finally, five case studies are presented in the third part of the document (Part 3). These works have been selected by some of the experts of the LaMed project and provide insights on: 1) the lagoon of Venice, the most exhaustively studied coastal lagoon in the whole Mediterranean; 2) the Doñana area, an interesting example of productive wetlands dedicated to sustainable aquaculture in Spain; 3) the state of the European eel resource and its exploitation and elements for the preparation of a common management plan in the GFCM area; 4) the status of advice and management of European eel towards a stock-wide assessment and; 5) the indicators on the sustainability of Mediterranean coastal lagoons. iv CONTENTS PART 1.

These analyses suggested the paraphyly of the genus Liza and also that the separation of Liza, Chelon and Oedalechilus might be unnatural. Moreover, all the species of the genus Mugil plus orthologs of Crenimugil crenilabis clustered together; however, molecular analyses suggested possible introgressions in Mugil cephalus and moreover, that fish identified as Mugil curema could correspond to two different species as already shown by karyotypic analyses. Keywords: Mugilidae, grey mullets, mitochondrial DNA, Mugil cephalus, introgression. INTRODUCTION We have focused this study on Mugilid species for which both cytochrome b (cytb) and 16S rDNA mtDNA sequences The family Mugilidae, commonly referred to as grey have been already published. Their geographic distributions mullets, includes several species which have a worldwide are briefly presented here. Oedalechilus labeo is limited to distribution; they inhabit marine, estuarine, and freshwater the Mediterranean Sea and the Moroccan Atlantic coast, environments at all latitudes except the Polar Regions [1]; a whereas, Liza and Chelon inhabit also the Eastern Atlantic few spend all their lives in freshwater [2].

Abstract: Vast amounts of fish bone lie preserved in Denmark’s soil as remains of prehistoric fishing. Fishing was particularly important during the Atlantic period (ca. 7,000-3,900 BC, i.e., part of the Mesolithic Stone Age). At this time, sea temperature and salinity were higher in waters around Denmark than today. Analyses of more than 100,000 fish bones from various settlements from this period document which fish species were common in coastal Danish waters at this time. This study provides a basis for comparing the fish fauna in the warm Stone Age sea with the tendencies seen and predicted today as a result of rising sea temperatures.

  • Some Targeted Reference Points for Thin Lip Grey Mullet Liza Ramada Management in Bardawil Lagoon, North Sinai, Egypt Sahar F
    OPEN ACCESS Freely available online Aquacu nd ltu a r e s e J i o r u e r h n s a i Fisheries and Aquaculture Journal l F ISSN: 2150-3508 Research Article Some Targeted Reference Points for Thin Lip Grey Mullet Liza Ramada Management in Bardawil Lagoon, North Sinai, Egypt Sahar F. Mehanna*, Mohammed G. Desouky, Ahmed F. Makkey National Institute of Oceanography and Fisheries, Fisheries Division, Suez, Egypt ABSTRACT The evaluation and management of fisheries resources requires knowledge of spatial and temporal changes in the habitat-associations of fishes as well as studying the biology and dynamics of commercial fishes of that fishery. The thin lip mullet, L. ramada is one of the most important and high valued species in Bardawil lagoon, Egypt. Long term commercial catch statistics show a significant decrease in the commercial landings of grey mullet in Bardawil lagoon since 1995. By learning more about this species and protecting the habitat upon which it depends, we can ensure that this important valuable fish remains abundant. Age was determined based on scale’s readings of fish collected in May 2017 to December 2017 and in May 2018 to October 2018. Growth parameters, mortality rates, exploitation level as well as the critical lengths and ages were estimated. Based on yield per recruit analysis, the mullet fishery in Bardawil lagoon was found to be heavily exploited. The study suggested some applicable reference points for sustaining and optimizing the thin lip grey mullet yield in Bardawil lagoon. Keywords: Egypt; Bardawil lagoon; Mugilidae; Population dynamics; Management INTRODUCTION many detailed information such as age and growth, mortality and exploitation rates should be available.

Recently, several compounds with endocrine disruption ability have been included in the list of priority substances and therefore, implementation of biomarkers assessing the presence and the effects of such substances are required. In the present work we applied a battery of chemical and biological markers in order to study the effects of endocrine disruptors in four thicklip grey mullet (Chelon labrosus) populations from the Basque Country (Bay of Biscay) inhabiting differently polluted estuaries: Arriluze and Pasaia are marinas located in highly industrialized and densely populated areas, Plentzia is a leisure and touristic town and Gernika is located in the Biosphere Reserve of Urdaibai. Chemical analyses of fish bile were performed in order to determine the uptake of endocrine disruptors. Liver, gonad and brain samples were collected for the study of expression levels of genes associated with reproduction and development such as vtg, cyp19a1 and a2, er and rxr.
