Book Description
Most of the major impacts of fishing on the ecosystems recorded around the world occur in the Mediterranean. This variety of interactions is due to four main interrelated factors: the wide range of fishing gear and practices; very intensive fishing; a high diversity of exploited habitats, ranging from shallow water to the deep-sea and oceanic domain; and high biological diversity.

Book Description
Based on the most recent scientific data, and without neglecting historical publications, Fishes in Lagoons and Estuaries in the Mediterranean 3 comprehensively details Mediterranean lagoonal–marine migratory fish. It provides information regarding their systematics, ecobiology, ethology, genetics and their exploitation. This volume, third in a set of books on Mediterranean ichthyofauna, offers a synthesis of the knowledge acquired from 1890 to the present day for each of the 21 species most frequently found in Mediterranean lagoons and estuaries. These species are detailed across two volumes, 3A and 3B. The scientific data presented in this book concern their lagoon life as much as their marine life, and are therefore of particular interest for both the management of fish stocks and for the conservation of species. Designed to give rapid and comprehensive access to the body of knowledge on Mediterranean lagoonal and estuarine migratory fishes, this volume is for anyone involved in the use, management or protection of natural environments and their populations, including ecobiologists, geographers, engineers, teachers, students and researchers.

Book Description
Fishes in Lagoons and Estuaries in the Mediterranean 2 extensively covers the systematic, biological, ecological, behavioral and genetic aspects of the sedentary fishes that spend their entire lifecycle in the coastal fringes, sometimes referred to as “extreme environments”. This second volume of a set of books on Mediterranean ichthyofauna presents in-depth scientific, historical and current knowledge at the family, genus and species levels. Designed to give rapid and comprehensive access to the body of knowledge on Mediterranean lagoonal and estuarine sedentary fishes (over 1200 scientific works are referenced), this volume is for anyone involved in the use, management or protection of natural environments and their populations, including ecobiologists, geographers, engineers, teachers, students and researchers.

Book Description
This atlas aims to present sound approaches to maturity sampling for a wide range of Mediterranean species – including bony fish, cartilaginous fish, both oviparous and viviparous, crustaceans and cephalopods – based on an accurate determination of the different maturity stages. It includes macroscopic photos of gonads belonging to the main species and, for some, a validation-based histological analysis.

Book Description
This is a detailed, illustrated and up-to-date study of the fauna, flora, landscapes, coastal areas and seascapes of the entire Mediterranean Basin, and the Sea itself. Since the publication of the first edition in 1999, the field has advanced in significant ways and this revision is timely.

Book Description
The wide variety of marine species of the Mediterranean and the Black Sea, found in different geographical subregions and habitats, has led to the development of a highly diversified fishing sector characterized by a broad range of fishing gear. Over time, harvesting marine resources has become more efficient due to a progressively improving understanding of the habits and behaviours of the various target species. In order to find ways to conserve fish resources and the marine environment, there is a need to further study these different types of fishing gear as well as to develop less impactful techniques. To this end, a comprehensive overview of fishing gear and methods in use in the Mediterranean and the Black Sea can facilitate the mitigation of incidental catch of vulnerable species, the mitigation of adverse impacts of fisheries on juvenile fish and discards, the decarbonization of fishing fleets through more energy efficient gear, the development of innovative gear to remove marine litter, and the reduction of lost, abandoned and otherwise discarded fishing gear, to name a few. This catalogue aims to provide such an overview and to describe the main technical characteristics and modes of use of fishing gear in operation in the region, considering specificities and differences not only at the regional level but also at the country and local levels.

Book Description
The main themes of the Symposium were biodiversity in enclosed and semi-enclosed seas and artificial habitats, and the restoration of degraded systems. These themes are highly relevant today. The papers dealing with the first theme represent current research and concerns about marine biodiversity in enclosed seas. The papers in the second theme represent a synthesis of up-to-date knowledge on artificial habitats.

Book Description
Bycatch – a term widely used to refer to part of the catch unintentionally caught during a fishing operation, in addition to target species, and consisting of the discards and incidental catch of vulnerable species – is considered one of the most important threats to the profitability and sustainability of fisheries, as well as to the conservation of the marine environment and ecosystems. Understanding the bycatch issue and adopting effective measures in order to reduce bycatch rates are essential steps towards minimizing the impacts on vulnerable species and ensuring both a sustainable fisheries sector and healthy seas. In the Mediterranean and the Black Sea, the incidental catch of vulnerable species – namely seabirds, sea turtles, elasmobranchs, marine mammals and macrobenthic invertebrates – represents one of several challenges for the industrial, semi-industrial and small-scale fisheries that coexist in the region, as well as for the diverse and sensitive ecosystems impacted. Typically, data on this issue have been collected in an opportunistic manner and in ways that make comparisons difficult. The annual absolute values of incidental catch of vulnerable species are not available: studies cover only a small portion of the total fishing activity and often present important knowledge gaps for many types of fishing gear, countries and/or subregions, as well as on temporal scales, for example, to establish reliable baselines. The result is that little is known of the scope of the problem, despite incidental catch being a significant pressure on the populations of vulnerable species, as well as a concern for fishers.This regional review is an attempt to compile, in one single document, all available data and historical records on the incidental catch of vulnerable species in the Mediterranean and Black Sea fisheries, obtained from existing literature, databases and other grey sources, and collated in a standardized and comparable way. The main objective is to provide comprehensive baseline information, earmark the main data gaps, as well as identify the most impacting types of fishing gear by taxonomic group. This work is a reminder of the importance of standardized data collection and the need to have baseline information in order to support decision-making in the identification of appropriate bycatch mitigation techniques, thus enabling analysis of their effectiveness and comparison over time and space, as well as facilitating the implementation of relevant conservation and/or management measures at the national, subregional and regional levels.
