This exciting new reference offers a wealth of practical and technical information on the chemical, physical, and biological effects of intensive rearing conditions on hatchery fish, and the adverse effect these factors can have on their health and physical condition. A unique combination of theory and practical applications is presented throughout the book, providing the scientific basis for managing water quality, fish cultural procedures, and the biological interactions of the fish being produced to prevent diseases and costly production losses. The book begins with a discussion of the physiological functioning of fish under normal conditions. It then explains the interactions between fish and the chemical factors in the rearing environment, including effects of the algal toxins that currently cause serious economic losses in freshwater and marine aquaculture operations world-wide. The next chapter covers the physiological effects of common fish cultural procedures, with emphasis on crowding (density tolerance), handling, and transportation, and effects on smolt development of anadromous salmonids. This section is followed by a discussion of the stress and disease problems that can result from biological interactions between the fish themselves and between fish and facultative and obligate microbial pathogens present in the rearing environment. Emphasis is on methods of preventing stress and disease problems in this section. The book concludes by exploring the biological, physical, and chemical methods of minimizing the fish pathogen load in hatchery water supplies. Thorough and complete, this indispensable resource provides professionals in fishery, biology, aquaculture, and naturalresource management with the basic technical knowledge needed to improve management of the interactions between fish and the chemical, physical, and biological factors in the rearing environment. In addition, this book will serve as a useful text for undergraduate and graduate students enrolled in fishery, biology, and zoology.

Islands are special because they promote unique forms of life, and large proportions of the species they hold are found nowhere else on Earth. The mammals of the South-west Pacific are no exception, with many distributed only across single islands or archipelagos. Mammals of the South-west Pacific details the natural history for more than 180 species of marsupials, bats and rodents from 24 Pacific nations and territories. Species profiles are accompanied by distribution maps, illustrations and photographs – many being the first images ever captured for the species. By combining available knowledge with unpublished data collected over years of field work, Mammals of the South-west Pacific forms a definitive guide to the mammals from this region.

The management of common pool resources and publicly-owned areas is fraught with difficulty. This book explores the long, complex, and frequently contentious history of public lands management in the United States in order to draw lessons for the emerging field of marine spatial planning (MSP). The author first establishes that these two seemingly different settings are in fact remarkably similar, drawing on established theories of policy analysis. The work then examines the management of US National Forests over the past 120 years, including three place-based case studies, to discover recurring themes. The analysis shows how different management approaches evolved over time in response to changing laws and cultural norms, producing outcomes favored by different constituencies. This history also reveals the ambiguities and contradictions inherent in multiple-use management of any public space. Next, the book analyzes recent efforts to advance MSP, both in the US and globally, showing how they mirror past experiences in National Forest management, including similar disagreements among stakeholders. In conclusion the author suggests how those within ocean-related sectors - government, academia, industry, and environmental groups - might achieve their individual and collective goals more effectively based on lessons from the public lands setting.

This book is the first to report that research in allogenics/xenogenics has conclusively shown that fishes have retained bisexual potency even after sexual maturity and spermiation. The XY genotype found in the unexpected female phenotypes sired by supermales (Y1Y2) and androgenic males (Y2Y2) points out the need to employ sex specific molecular markers to identify the true genotype of a juvenile, which matures either as a male or female, depending upon the sex of its pair (female or male) and thereby critically assessing the environmental role in sex determination. This book is meant to assist molecular biologists in the search of sex determining gene(s), fishery biologists endeavouring to develop techniques for profitable monosex aquaculture and ecologists interested in conservation of fishes and their genomes.

This comprehensive book provides first-hand information on the diversity, biology, and ecology of venomous stingrays of freshwater, brackish, and marine ecosystems. Each year thousands of injuries to swimmers and surfers are reported, with 750 to 1,500 stingray injuries reported each year in the US alone. As more vacationers spend their leisure time exploring coasts and tropical reefs, often in isolated areas without immediate access to advanced health care, there will be greater potential for stingray injuries. A thorough understanding about the diversity of stingrays of marine and freshwater ecosystems and their injuries and envenomations would largely improve the public health community's ability to better manage and to prevent stingray injuries. This volume fills that gap. With over 200 photos and illustrations, this book shows the characteristics of venomous stingray families along with other profile information, such as common name, geographical distribution, diagnostic features, reproduction, predators, parasites, the International Union for Conservation of Nature's conservation status. Importantly, it includes valuable information on stingray injuries, envenomation, and medical management. This volume will be very informative for students of fisheries science, marine biology, aquatic biology, and environmental sciences, and will become a standard reference for marine professionals, health practitioners, and college and university libraries, and as a helpful on-board

Energy from wave and tidal power is a key component of current policies for renewable sources of energy. This book provides the first comprehensive exploration of legal, economic, and social issues related to the emerging ocean energy industry, in particular wave and tidal energy technologies. This industry is rapidly developing, and considerable technical literature has developed around the technology. However, it is shown that challenges relating to regulation and policy are major impediments to industry development, and these aspects have not previously been sufficiently highlighted and studied. The book informs policymakers, industry participants, and researchers of the key issues in this developing field. Ocean energy is considered in the context of the blue economy and an industrialising ocean, and the topics covered include: development of policy (policy instruments, risk and delay in technology development); legal aspects (consenting processes, resource management, impact assessment); human interactions (conflicts, consultation, community benefits); and spatial planning of the marine environment. While offshore wind energy, sited in the oceans but not strictly derived from the ocean, is not the primary focus of the book, there is also discussion of the similarities and differences between offshore wind and wave and tidal power policy dimensions.

This book critically examines the available literature on oceanic acidification: including a historical review of pH and atmospheric CO2 levels over the millennia; natural and anthropogenic sources of CO2 to the atmosphere and sea surface; chemical, physical, and biological mode of action; biological effects of acidification to marine plants and animals under laboratory conditions; field observations on seawater chemistry and effects of declining pH; and various technical and political mitigation strategies. Written by Dr. Ronald Eisler, a noted authority on chemical risk assessment, the book summarizes real and projected effects of oceanic acidification.

The greatest complexity of the immune response is shown by vertebrates which are endowed with innate and acquired immunity. Immunological studies performed mostly in mammals have been the reference for studies in other vertebrates. The study of immunological fish defenses has advanced considerably in recent decades. This has been due to the key status of fish in terms of the evolution of acquired immunity and due to the rapid expansion of aquaculture over this period, wherein disease control is of prime concern. Most of the chapters not only review the current advances on fish immune defenses, but also show perspective for future research. The book will be of interest to scientists involved in fish immunology, fisheries and aquaculture as well as for students of fish biology.

Innovative packaging solutions for fish products are explored, detailing intelligent packaging with freshness and time-temperature indicators, applications of modified packaging atmosphere, antimicrobial bio-nanocomposite packaging materials and biodegradable edible films used as primary fish packaging. In addition to covering the current advancements in fish processing the book discusses fraud, adulteration, fair trade practices, traceability and the need for added value, clean and sustainable processing in the fish chain.

Fingerponds are earthen ponds dug at the edge of natural wetlands and stocked naturally with wild fish during flooding. They preserve the wetland environment in which they are situated while maintaining a productive culture system. In this study, the importance of organic manure applications in enhancing nutrient levels, phytoplankton and periphyton productivities and ultimately fish production was examined in experimental Fingerponds set up with the participation of local communities in Uganda. Results show that organic manures enhance algal development and fish production in Fingerponds, but close monitoring and control are needed. Fish yields in Fingerponds can be enhanced to 1500 - 2800 kg/ha over a functional period of 200 to 300 days using animal manure (e.g. chicken), fermented green manure and artificial substrates for periphyton development. Good management practices are required to regulate pond inputs and conditions. High clay turbidity, nitrogen limitation and high recruitment of fish can limit fish production. Overall, Fingerponds were shown to be an effective addition to protein production for poor riparian communities in East Africa and are recommended for adoption.

Estuaries in every country exemplify the same paradox - they are among the most productive ecosystems and also among the most impacted by anthropogenic activities. And although estuarine biodiversity is key to the ecological and economic health of coastal regions, estuaries are exposed to toxic effluents transported by rivers from remote and nearby conurbations and industrial and agricultural concerns, putting them at risk. Increased attention to environmental issues highlights the fragility and importance of estuaries and brings to the forefront the need for an up-to-date assessment of techniques. Environmental Assessment of Estuarine Ecosystems: A Case Study describes a comparative, multidisciplinary ecotoxicological study of two contrasting estuaries in France. Based on the results of this study, the book presents generalizations about how different techniques might be applied and interpreted in future, similar studies assessing the ecotoxicological status of these vital coastal systems. With contributions from international experts, this reference covers all aspects of estuaries from the physiological to the economical. It introduces the state-of-the-art science required to investigate ecotoxicological problems in many estuaries all over the world. Although carefully focused on a specific region, this book covers a broad range of environmental issues and solutions, demonstrating how various pieces of information can be integrated into a sound assessment. Understanding the observations about this region and the techniques used for its assessment provide a benchmark for assessing, remediating, and applying new developments to other estuaries.
