In this report knowledge on fish passage from both the biological and the engineering perspectives, including basic aspect on fish biology and behaviour relevant to fish migration, different types of fish passage facilities, ecological and hydrological requirements for enhancing the effectiveness of fish passages, as well as the monitoring, evaluation and maintenance of fish passages, is presented.

In the last decades, the human harvesting of marine resources became more efficient as the understanding of the habits and behaviours of the various species available in the sea gradually increased. Technologies naturally developed over time and fishing systems became more sophisticated and increasingly adapted to catch the most desirable species and sizes. This evolution is still in progress and technological development goes on especially in the Mediterranean area, where small and relatively old fishing vessels are traditionally used. These technical advances in fishing gears have generally led to more efficient fishing operations and improved access to resources and fishing grounds. On the other hand, general awareness on the environmental problems due to the exploitation of fisheries resources has also increased. Therefore, in order to preserve fishery resources and marine environments, fishing gears and their impacts need to be further investigated and less impacting techniques should be developed. In this regard, fishing technologists are responsible to provide fishery managers as well as fishermen and stakeholders, with useful advice and technical solutions for mitigating adverse impacts of fishing gears. By taking these problems into account, the book contents are based on the requirements of ecosystem-approach to fisheries management. The Code of Conduct for Responsible Fisheries of the FAO (1995) encouraged the use of selective, environmentally safe and cost effective gear and techniques. Thus the book aims at providing information on sustainable fishing technologies, and transfers the expertise on fishing technology to Mediterranean fisheries scientists and end-users such as fisheries managers, administrators, controllers etc. This book is structured to provide information on fishing gear technology, selectivity, bycatch-impact reduction and fishing vessel technology, with particular attention to the Mediterranean context. The information included might be used to learn how to assess the impacts and selectivity of different fishing gears and find technical solutions to mitigate these impacts and to address scientific studies. Furthermore, advices on the properties of fishing vessels affecting energy efficiency have been also considered in order to address possible technical changes to the currents boats. Finally the contents of this book might be considered as a useful tool when preparing management measures as well as for the establishment, enforcement or improvement of fishing rules.

This comprehensive publication "Handbook on Freshwater Aquaculture" is the collective effort of a wide array of eminent people associated with Indian aquaculture. Special emphasis has been given to aquaculture and its prospects and problems in rural India especially the lesser known areas. The book covers almost all important aspects of freshwater aquaculture, both traditional and modern aquaculture techniques, water quality issues, integrated farming practices, environmental, socio-economic and livelihood issues. It is expected that the book will prove to a source of useful information for the needs of students, scholars, farmers and researchers.

Aquaculture is one of the fastest growing sectors of agriculture globally. Production in freshwater and marine fisheries has plateaued or is declining, and the increasing demand for seafood and need for affordable protein sources in third world countries will ensure growth of aquaculture in the future. Tilapia are the second most cultured fish world-wide behind the carps, and even though they are easily cultured in a wide variety of environments and are relatively resistant to aquaculture stressors compared to other cultured finfish species, significant losses to disease still occur under intensive culture. This book discusses the biology, management practices and human consumption of tilapia.

In general, aquaculture and fish farming cause negative impacts on the environment and wild fish populations. One of the major problems is the escape of farmed fish, especially exotic species, which can alter the population dynamics and ecology of wild stocks. Therefore, the reduction or even extinction of natural stocks may occur through predation and/or competition for resources. This book discusses the biology, behaviour and conservation strategies of both carp and catfish.

Japan is one of the world's largest fish-eating countries with a long history, and has developed its own customs and values in terms of managing fisheries resources. The first half of this book introduces the history and institutional features of capture fisheries management in Japan, with 9 case studies from sub-arctic to tropical ecosystems, from sedentary to migratory species, and from small-scale coastal to offshore industrial fisheries. For example, coastal fisheries management is more community-based, and local people have the authority and take priority in the decision-making process. In contrast, offshore fisheries are more industrialized and commercially oriented, and the national government plays a major role in their management. One of the main challenges in world fisheries is to implement the ecosystem approach, but there is no one-size-fits-all solution for its implementation. The second half of this book considers the advantages and limitations of the Japanese fisheries management regime and discusses the necessary environmental policy measures to bridge the gaps between fisheries management and ecosystem-based management. As a case study, management measures in the Shiretoko World Natural Heritage area are analyzed. In closing, the Grand Plan of Japanese fisheries policy for the next 20 years and three future scenarios are presented.

This volume is an interdisciplinary mix of perspectives and studies on social issues in fisheries from a diverse range of case studies and research disciplines. The case is made regarding the dearth of attention to socio-cultural considerations which to date have been largely treated as an externality of fisheries policy. It will be valuable to researchers and decision makers interested in understanding the social dimension of fisheries and provides a timely and relevant compilation of research and analysis on some of the critical socio-cultural issues facing fisheries management and fishing communities today.

I pull on my balaclava and step onto the bridge wing. It's loud outside- I can hear the rumbles of nine vessels' engines and the hiss of ten water cannons ...suddenly the bridge is full of refugees from the upper deck. They are blocking my view out the back windows, but their faces - afraid, excited, awestruck - illustrate the looming presence of the Nisshin. I bend my knees and grip the bench, ready for the crunch. In Blood and Guts, Sam Vincent plunges into the whale wars. Vincent sets sail with Sea Shepherd, led by the charismatic and abrasive Paul Watson. He attends the recent case at the International Court of Justice, which finds Japan's 'scientific' whaling in the southern Ocean to be unlawful. And he travels to Japan to investigate why its government doggedly continues to bankroll the unprofitable hunt. This is a fresh, funny and intelligent look at how Australia has become the most vocal anti-whaling nation on Earth. Vincent skewers hypocrisy and sheds light on motives noble and otherwise. With Japan planning to relaunch its lethal program in 2015, the whale wars are set to continue. Blood and Guts is a riveting work of immersion journalism that lays bare the forces driving this conflict.

Catch share programs are a fishery management tool that dedicates a secure share of quota allowing individual fishermen, fishing cooperatives, fishing communities, or other entities to harvest a fixed amount of fish. With clearly defined fishing privileges, fishermen no longer need to "race to fish," but instead can make harvest decisions based upon market conditions, improving economic performance, and weather conditions, which improves crew safety. These incentives can reduce the cost of taking conservation actions and can encourage individual fishing choices that are more consistent with sustainable fishing practices such as reducing low-value or undersized catch that is discarded at sea but is frequently associated with high mortality rates. The ability to align fishermen's economic incentives with the long-term biological health of the fishery singularly distinguishes catch share programs from traditional fishery management strategies (i.e., trip limits, gear restrictions, etc.). Nationwide, there are 15 catch share programs currently in operation. This book provides basic information on the economic performance of U.S. catch share programs using a standard set of indicators that are uniformly applied across these highly diverse programs.

This informative new volume on the reproduction and development of zebrafish provides a timely and fundamental set of chapters presenting new data and critical reviews to the novice student and veteran researcher alike. It covers two major areas of zebrafish biology, reproduction and development, with toxicology emphasised in a number of chapters. Historically, reproductive biology of zebrafish has not been given the attention afforded to the more intensively studied aspects of embryonic development in this model species. In part, this may be due to fewer tools available to zebrafish reproductive biologists. However, with the advent of transparent juvenile and adult lines, new areas of reproduction research become visible both figuratively and literally. Two chapters are devoted to presenting these exciting new fish lines and examples of their use in research to the reproductive biology research community. Reproduction and embryonic development are a continuum which is emphasised in a new review on RNA-binding proteins in the zebrafish oocyte. It is increasingly clear that embryonic development is dependent upon factors present in the female gamete known collectively as "maternal effects", and these oocyte components are beautifully summarised in this chapter. Other chapters cover normal spawning periodicity and vitellogenic oocyte growth dynamics that should interest ovarian physiologists and those interested in zebrafish husbandry.

This book provides a good mix of both basic and applied topics in the hope that it will be useful and of interest to scientists working on finfish. It has 15 chapters written by 27 contributors and many of them are highly respected scientists. Given the global importance of salmon, contributors are from many countries including 11 from Japan and Russia. These authors bring slightly different and important perspectives to the book, and their expertise and research may not be known to many young scientists in Europe and in the Americas. The volume starts with an overview of salmon, their economic and social importance, and their impacts on the environment. Subsequent topics include morphological, physiological and behavioural differences between wild and farmed salmon; growth, food utilisation and water flow requirements of wild and hatchery salmon; the real and potential ecological impacts of sea cages and hatcheries; the potential use of waste product (gelatine) from the salmon industry; salmon behaviour and genetics including their broad applications that contribute to our understanding of fish biology, and nutritional and anti-nutritional factors in salmon culture. There are also chapters on environmental impacts and the economic importance of the commercial fishery and salmon farming industry; these are very important components of the industry, especially to the seafood sector.

Narrowing in from the broader context of the north Atlantic, through northern Europe, to Britain, northeast Scotland, and finally the fishing village of Gamrie, this anthropology of Protestantism examines millennialist faith and economic crisis. Through his ethnographic study of the fishermen and their religious beliefs, Webster speaks to larger debates about religious radicalism, materiality, economy, language, and the symbolic. These debates (occurring within the ostensibly secular context of contemporary Scotland) also call into question assumptions about the decline of religion in modern industrial societies. By chronicling how these individuals experience life as "enchanted," this book explores the global processes of religious conversion, economic crisis, and political struggle.

Following from Fish for Life Interactive Governance for Fisheries (Kooiman et al., 2005), which presents an interdisciplinary and intersectoral approach to the governance of capture and aquaculture fisheries, this volume pursues what interactive governance theory and the governability perspective contribute to the resolution of key fisheries problems, these include overfishing, unemployment and poverty, food insecurity, and social injustice. Since these problems are varied and can be felt among governments, resource users and communities globally, thediagnosis must be holistic, and take account of principles, institutions, and operational conditions. The authors argue that wicked problems and institutional limitations are inherent to each setting, and must be included in the analysis. The volume thereby offers a new lens and a systematic approach for analysing the nature of problems and challenges concerning the governance of fisheries, explores where these problems are situated, and how potential solutions may be found.""

" It now seems clear that the crisis in the world s fisheries is] a much larger and more complex problem than many had imagined. Yet, examining it through the lens of governability may offer the best hope for alleviating it--as well as alleviating similar crises in other social systems. "James R. McGoodwin (Professor Emeritus, University of Colorado)
