Freshwater fishes are one of the great natural resources of the world, but anthropogenic activities have adversely affected aquatic ecosystems and many species are threatened with extinction. Throughout the 1900s, the distribution and abundance of native freshwater fishes in inland and coastal drainages in southeastern Australia were significantly reduced, and there were extirpations of some populations. This chapter reviews these declines and the use of captive breeding and stocking programmes since the late 1970s to aid the recovery of threatened species, establish and maintain large recreational fisheries, and restore lost biodiversity. The successes of these programmes have been due to the development of best practices for broodfish management, artificial breeding, larval rearing, fingerling production and management of infectious diseases, and guidelines which minimise the effects of domestication, maintain genetic identity of stocked populations, and maximise genetic variation providing a basis for fitness and evolutionary potential of each species.

Aquaculture Health Management: Design and Operation Approaches is an essential reference for the diverse aquaculture community. With the steadily increasing importance of healthy fish production and the expansion of the animal aquaculture industry to new geographic areas, new microbial and parasitic species with pathogenic potential continue to emerge. The book covers the broad spectrum of fish and shellfish health, the functional roles of pathogen emergence, and the impacts of nutrition and preventative medicine such as pre- and probiotics, as well as chemical treatments, relevant legislation and more. This reference takes a comprehensive approach to understanding overall fish health management, making it valuable to aquaculturists, practitioners in aquatic animal health, veterinarians and all those in industry, government or academia who are interested in aquaculture and fisheries and their sustainable futures. - Presents the biosecurity measures used to prevent the spread of disease - Discusses fish immunology to help readers understand preventive medicine for a healthy fish production - Examines the latest scientific methods and technologies to maximize efficiencies for healthy fish production for farming - Includes the most commonly researched fish, crustaceans and mollusks in aquaculture

This document is directed to aquaculture development specialists, coastal resource use planners and government officials involved and interested in the planning and management of coastal aquaculture development within the wider context of resource use in coastal areas. It is intended to serve in the promotion of environmental management of coastal aquaculture. Guidelines are given for improved environmental management of coastal aquaculture based on an overview of selected published experiences and concepts. Potential adverse environmental effects of and on coastal aquaculture practices are addressed with consideration of main socio-economic and bio-physical factors. Methodologies are presented for the assessment and monitoring of environmental hazards and impacts of coastal aquaculture. Selected environmental management options are described for application both at policy-level and farm-level.

It is now accepted that humans are changing the climate of the Earth and this is the most compelling amongst a long litany of reasons as to why, collectively, we have to change our ways of thinking and acting. Most people now recognise that we have to be capable of adapting quickly as new and uncertain circumstances emerge: this capability will need to exist at personal, group, community, regional, national and international levels, all at the same time. Systems Practice is structured into four parts. Part I introduces the societal need to move towards a more systemic and adaptive governance against the backdrop of human-induced climate change. Part II unpacks what is involved in systems practice by means of a juggler metaphor; examining situations where systems thinking offers useful understanding and opportunities for change. Part III identifies the main factors that constrain the uptake of systems practice and makes the case for innovation in practice by means of systemic inquiry, systemic action research and systemic intervention. The book concludes with Part IV, which critically examines how systems practice is, or might be, utilised at different levels from the personal to the societal. The development of our capabilities to think and act systemically is an urgent priority and Systems Practice aims to show how to do systems thinking and translate that thinking into praxis (theory informed practical action) which will be welcomed by those managing in situations of complexity and uncertainty across all domains of professional and personal concern.

There has been a continual expansion in aquaculture, such that total production is fast approaching that of wild-caught fisheries. Yet the expansion is marred by continued problems of disease. New pathogens emerge, and others become associated with new conditions. Some of these pathogens become well established, and develop into major killers of aquatic species. Diagnosis and Control of Diseases of Fish and Shellfish focuses on the diagnosis and control of diseases of fish and shellfish, notably those affecting aquaculture. Divided into 12 chapters, the book discusses the range of bacterial, viral and parasitic pathogens, their trends, emerging problems, and the relative significance to aquaculture. Developments in diagnostics and disease management, including the widespread use of serological and molecular methods, are presented. Application/dose and mode of action of prebiotics, probiotics and medicinal plant products used to control disease are examined, as well as the management and hygiene precautions that can be taken to prevent/control the spread of disease. This book will be a valuable resource for researchers, students, diagnosticians, veterinarians, fish pathologists and microbiologists concerned with the management of diseases of fish and shellfish.

Published in Cooperation with THE WORLD AQUACULTURE SOCIETY Aquaculture loses millions of dollars in revenue annually due to aquatic animal diseases. Disease outbreaks continue to threaten profitable and viable aquaculture operations throughout the world. As a result, aquaculture biosecurity programs that address aquatic animal pathogens and diseases have become an important focus for the aquaculture industry. Aquaculture Biosecurity: Prevention, Control, and Eradication of Aquatic Animal Disease provides valuable information that will increase success in combating infectious aquatic disease. Key representatives of international, regional, and national organizations presented their views on this important issue as part of a special session at the 2004 World Aquaculture Society Annual Conference. The chapters of this book cover a wealth of experience from the varied perspectives of these experts on biosecurity, policies, and measures to take the offensive against the spread of diseases in aquatic animals. With contributions from renowned international experts, covering approaches to biosecurity policies and measures currently practiced, Aquaculture Biosecurity: Prevention, Control, and Eradication of Aquatic Animal Disease is a vital reference for all those concerned about protecting aquaculture from impacts of aquatic animal disease.
