Annotation Many of the world's fisheries are in trouble - they no longer yield the catches, and potential profits, they once did. The habitats that support fisheries have been damaged by pollution and other irresponsible use of coastal land. Destructive fishing methods like trawling and blast fishing have also changed fish habitats resulting in support of fewer fish. The authors draw on more than 1000 scientific papers covering 11 groups/species of marine invertebrates. From this large literature, they distill 20 lessons for assessing and guiding the use of restocking and stock enhancement in the management of invertebrate fisheries. · Written by 7 expert authors · Covers 11 groups/species of marine invertebrates · Reviews over 1000 scientific papers · Identifies 20 lessons that can be learned from past restocking and stock enhancement initiatives · Proposes a new approach to assess the potential value of hatchery releases to complement other forms of management · Assesses progress of disciple against the blueprint for a responsible approach.

During the last decades, aquatic resources have been severely depleted due to human-induced factors such as overexploitation and pollution and more recently due to deviations in the physicochemical parameters of oceans, dramatic changes in weather patterns and melting of glaciers. The effects of these man-made factors are occurring in a relatively shorter time scale and, in many cases, are beyond the capacity of organisms to adapt to these deviations. The majority of natural aquatic resources, which are one of the most important food sources on the planet, are being used to the extent that limits their capacity for regeneration. Despite ongoing attempts towards developing strategies for long-term management of aquatic resources all over the world, efforts have met with limited success. Thus, the sustainable use of aquatic resources has become a very important reality considering a projected human population of 11 billion by the year 2100. With this reality in mind, the purpose of this book is to shed more light on the field of marine ecology by emphasizing the diversity of aquatic life on earth and its importance both as part of a balanced ecosystem and as part of critical source of food on earth. The book covers important findings, discussions and reviews on a variety of subjects on environmental and competitive interactions of marine organisms at different trophic levels and their effects on the productivity, dynamics and structure of marine ecosystems around the world. Each chapter focuses on a specific case in the field of marine ecology and was written by researchers with years of experience in their respective fields. We hope that academicians, researchers and students as well as experts and professionals working in the field of marine ecology will benefit from these contributions. We also hope that this book will inspire more studies to help better understand the marine environment and develop strategies to better protect this crucial element of life on earth.

In this book, numerous prominent aquaculture researchers contribute 27 chapters that provide overviews of aquaculture effects on the environment. They comprise a comprehensive synthesis of many ecological and genetic problems implicated in the practice of aquaculture and of many proven, attempted, or postulated solutions to those problems. This is an outstanding source of reference for all types of aquaculture activities.

Mullets (grey mullets) are a family (Mugilidae) and order of ray-finned fish found in temperate and tropical waters worldwide. There are approximately 80 species of mullet; these fish have been considered an important food source in Mediterranean Europe since Roman times. This book provides a long overdue update on the biology and ecology of mullet

Whether it's throwing a fresh local prawn on the BBQ or dangling a line off the local jetty, fisheries resources are economically and socially important for many Australians. Australian fisheries have undergone significant management changes over the last decade and Australia is now recognised as a world leader.This book is a comprehensive analysis of fisheries management in Australia. It provides practical insight into the cross-disciplinary tools of fisheries management. It takes the reader away from the outdated notion of "managing the fish" to the reality of managing human behaviour. It does so without losing track of the fundamental need to consider the ecosystem and its components.The book covers a diverse range of contemporary topics including: sharing fisheries resources between commercial and recreational fishers, marine park planning, current regulatory and policy environments, consultative and participatory frameworks, by-catch mitigation and fisheries habitat management. It is a must for tertiary students studying fisheries, fisheries management professionals, the fishing industry and anyone else with an interest in how our valuable but finite fisheries resources are managed.

U.S. mariculture production of bivalve molluscs-those cultivated in the marine environment-has roughly doubled over the last 25 years. Although mariculture operations may expand the production of seafood without additional exploitation of wild populations, they still depend upon and affect natural ecosystems and ecosystem services. Every additional animal has an incremental effect arising from food extraction and waste excretion. Increasing domestic seafood production in the United States in an environmentally and socially responsible way will likely require the use of policy tools, such as best management practices (BMPs) and performance standards. BMPs represent one approach to protecting against undesirable consequences of mariculture. An alternative approach to voluntary or mandatory BMPs is the establishment of performance standards for mariculture. Variability in environmental conditions makes it difficult to develop BMPs that are sufficiently flexible and adaptable to protect ecosystem integrity across a broad range of locations and conditions. An alternative that measures performance in sustaining key indicators of ecosystem state and function may be more effective. Because BMPs address mariculture methods rather than monitoring actual ecosystem responses, they do not guarantee that detrimental ecosystem impacts will be controlled or that unacceptable impact will be avoided. Ecosystem Concepts for Sustainable Bivalve Mariculture finds that while performance standards can be applied for some broad ecosystem indicators, BMPs may be more appropriate for addressing parameters that change from site to site, such as the species being cultured, different culture methods, and various environmental conditions. This book takes an in-depth look at the environmental, social, and economic issues to present recommendations for sustainable bivalve mariculture.

Illuminating Hidden Harvests: the contributions of small-scale fisheries to sustainable development (hereinafter IHH) is a global study uncovering the contributions and impacts of small-scale fisheries through a multidisciplinary approach to data collection and analysis. The study provides information that quantifies and improves understanding of the crucial role of small-scale fisheries in the areas of food security and nutrition, sustainable livelihoods, poverty eradication and healthy ecosystems. It also examines gender equality as well as the nature and scope of governance in small-scale fisheries. The IHH study was carried out in support of the implementation of the Voluntary Guidelines for Securing Sustainable Small-Scale Fisheries in the Context of Food Security and Poverty Eradication (SSF Guidelines), themselves developed in recognition of the plight of small-scale fishers, fishworkers and associated communities and released as a contribution to the International Year of Artisanal Fisheries and Aquaculture 2022. The purpose of this report is to contribute to a more holistic understanding of what small-scale fisheries are, their importance, and why they are essential to efforts to achieve the Sustainable Development Goals (SDGs). By using this knowledge wisely within a human rights-based approach in line with the SSF Guidelines, and by empowering small-scale fishers and fishworkers, a more inclusive, equitable, sustainable and resilient small-scale scale fisheries subsector can be achieved. Realizing this goal would benefit hundreds of thousands in fishing communities and society at large. With this in mind, the IHH report is aimed at all those with a stake or an interest in the small-scale fisheries subsector, in particular decision-makers who are concerned with fisheries, poverty eradication, food security and nutrition, and sustainable development more generally. It is also addressed to small-scale fisheries actors themselves and those who support them.
