To properly conserve, restore and manage riverine ecosystems and the services they provide, it is pertinent to understand their functional dynamics. Growing human populations and high dependency on natural resources in developing countries have exerted pressure on land and water resources. However, there is a major knowledge gap concerning the influence of human activities on the functioning of tropical rivers in terms of organic matter processing and energy sources supporting riverine consumers. This thesis explores the functioning of tropical upland streams and savanna rivers by assessing the spatial and temporal dynamics in organic processing under different land-use and discharge conditions and the resultant influence on energy sources for riverine consumers. This thesis contributes to the theories of river functioning and has improved understanding of the functioning of African tropical streams by identifying a diverse macroinvertebrate shredder guild and determining its role in organic matter processing. This thesis also shows that large mammalian herbivores enhance terrestrial-aquatic food web linkages in African savanna rivers via the transfer of organic matter. The findings of this researcht are useful for defining future research needs and actions for sustainable management of agriculturally influenced streams and savanna rivers in landscapes witnessing declining wildlife populations and changing land uses.

Presents information that can be useful to facilitate the aquaculture of a wide variety of food species. Operation of an economically successful aquaculture venture depends upon the complete life cycle of a species occurring in captivity. Possible solutions to how such complete control of life cycles of important food organisms might be accomplished are presented in each chapter. Whereas this volume (Part A) deals with Seaweeds and Invertebrates, a compendium volume (Part B) deals with Fishes.

Aquaculture is increasingly complementing global fisheries and is relevant to ocean and freshwater health, biodiversity and food security, as well as coastal management, tourism and natural heritage. This book makes the case for treating the governance of this industry as meriting attention in its own right, abandoning the polemic discussions of fish farming and opening up new ways for debating its past, present and future. Developing and applying an original analytical framework for studying fish farming aquaculture, embedded into larger theory about the changing political system, the author generates and compares new data on the governance of aquaculture. Detailed case studies are presented of Scottish salmon, Aquitaine trout in France and seabass and seabream in Greece. The book shows how ecological issues are related to economic and social issues, as well as interdependences between territories, public and private regulation and different knowledge forms, demonstrating that these are creating alternative approaches for sustainability governance. It provides a deeper understanding of the political aspects of governing European aquaculture, including how it both is structured by and is structuring politics. It is aimed at advanced students, researchers and professionals in aquaculture and fisheries, as well as those with a broader interest in sustainability politics and sustainability governing practices.

Algae have been used since ancient times as food, fodder, fertilizer and as source of medicine. Nowadays seaweeds represent an unlimited source of the raw materials used in pharmaceutical, food industries, medicine and cosmetics. They are nutritionally valuable as fresh or dried vegetables, or as ingredients in a wide variety of prepared foods. In particular, seaweeds contain significant quantities of protein, lipids, minerals and vitamins. There is limited information about the role of algae and algal metabolites in medicine. Only a few taxa have been studied for their use in medicine. Many traditional cultures report curative powers from selected alga, in particular tropical and subtropical marine forms. This is especially true in the maritime areas of Asia, where the sea plays a significant role in daily activities. Nonetheless, at present, only a few genera and species of algae are involved in aspects of medicine and therapy. Beneficial uses of algae or algal products include those that may mimic specific manifestations of human diseases, production of antibiotic compounds, or improvement of human nutrition in obstetrics, dental research, thallassotherapy, and forensic medicine.

This unique book introduces the biological and ecological basis of the production process in water, and the biology of cultured species. It bridges the gap between research data and aquaculture techniques, and covers problems arising in aquaculture production, such as filtering molluscs. It also introduced modern aspects of oceanography that are important for understanding the production process. The book starts with a section dedicated to the production of living material and matter in the aquatic environment. It then goes on to explore in detail the biological basis of mollusc, crustacean and fish cultures, and the reproduction and nutrition of bivalve molluscs. Also discussed are the intensive and extensive aquaculture producing processes in fresh and marine waters, and finally the pathology reared animals. Up-to-date data are provided and explained to the student using graphs and copious illustrations. The work is especially orientated toward the student reader and provides a comprehensive and authoritative text on the subject.

The current scenario provides an ideal opportunity to confer higher priority to the marine resources of the Indian Ocean, particularly in terms of integrated management of the deep sea, shallow sea and coastal resources. This will maximize their potential in the sustainable development goal (SDG) pattern, leading to an appropriate environmental management. Therefore, this book aims to provide an overview of the area and to highlight the potential market opportunities represented by this vast and rapidly developing nation. In doing so the following aspects have been covered: Exclusive title focussing on mineral resources of Indian ocean. Discusses living, nonliving, ocean waves and tidal energy, ocean environment and protection aspects. Includes information on key themes, details of organizations associated with the Indian Ocean. Illustrates deep sea mining technology and environmental perspectives. Covers hydrocarbons-sub sea oil and gas, minerals from placer deposits to deep sea nodules, sea floor massive sulphides and cobalt rich encrustations.

The high market demand based on consumers' trust in fish as a healthy and nutritious food resource made fish processing a very dynamic industry, spurring many innovations in processing and packaging methods. Trends in Fish Processing Technologies not only reflects what is currently new in fish processing but also points out where things are heading in this area. This book provides an overview of the modern technologies employed by the industry. It details the advances in fish processing, including high pressure processing (HPP), pulsed electric field (PEF) treatment and minimally heat processing combined with microwave (MW) and radio-frequency (RF). It provides references to food safety management systems and food safety & quality indicators for processed fish in order to achieve an adequate level of protection. Quality aspects and molecular methods for the assessment of fish and fish products integrity are introduced. Fish products reformulation trends based on sustainability principles that tackles the reduction of salt content and the use of natural antimicrobials are presented. 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.

Access to genetic resources and Benefit Sharing (ABS) has been promoted under the Convention on Biological Diversity, with the aim of combining biodiversity conservation goals with economic development. However, as this book shows, since its inception in 1992, implementation has encountered multiple challenges and obstacles. This is particularly so in the marine environment, where interest in genetic resources for pharmaceuticals and nutrients has increased. This is partly because of the lack of clarity of terminology, but also because of the terms of the comprehensive law of the sea (UNCLOS) and transboundary issues of delineating ownership of marine resources. The author explains and compares relevant provisions and concepts under ABS and the law of the sea taking access, benefit sharing, monitoring, compliance, and dispute settlement into consideration. He also provides an overview of the implementation status of ABS-relevant measures in user states and identifies successful ABS transactions. A key unique feature of the book is to illustrate how biological databases can serve as the central scientific infrastructure to implement the global multilateral benefit sharing mechanism, proposed by the Nagoya Protocol. The research for this book was supported by both the Bremen International Graduate School for Marine Sciences (GLOMAR) and the International Research Training Group INTERCOAST - Integrated Coastal Zone and Shelf-Sea Research.

In this work, several modelling approaches are explored to represent spatial pattern dynamics of aquatic populations in aquatic ecosystems by the combination of models, knowledge and data in different scales. It is shown that including spatially distributed inputs retrieved from Remote Sensing images, a conventional physically-based Harmful Algal Bloom model can be enhanced. Also, Cellular Automata based models using high resolution photographs prove to be good in representing aquatic plant growth. Multi-Agent Systems can capture well the spatial patterns exhibited in GIS density maps. A synthesis modelling framework was developed to include biological/ecological growth and diffusive processes, and local effects in conventional modelling framework. The results of the complementary modelling paradigms investigated in this research can be of help in achieving a sustainable environmental management strategy.

Stock Assessment: Quantitative Methods and Applications for Small Scale Fisheries is a book about stock assessment as it is practiced. It focuses on applications for small scale or artisanal fisheries in developing countries, however it is not limited in applicability to tropical waters and should also be considered a resource for students of temperate fishery management problems. It incorporates a careful sample design, various mathematical models as a basis for predicting consequences for stock exploitation, and discusses the impact of exploitation on non-targeted species. This was a unique concept involving a collaborative effort between U.S. and host country scientists to address issues of regional and global concern through innovative research.
Unlike other books on stock assessment that show mathematical models, this is the only book of its kind that discusses how an assessment is carried out. It looks at the field as a whole and includes sampling, age determination and acoustics.
The book represents the culmination of a nine-year program financed by the United States Agency for International Development to provide new or improved methods of stock assessment for artisanal fisheries.

This new edition of the best-selling book describes the main types of fishways and fish facilities used around the world to assist the passage of fish over dams and other obstructions to their migration. It also focuses on the protection of fish (mainly young fish) from the hazards encountered in their downstream migrations. The book brings together the type of knowledge and research needed to decide on the facility used as well as its design and operation. It emphasizes the need for both biologists and engineers to collaborate in the design and indicates in what fields such collaboration would benefit fisheries conservation in the future. This is the Second Edition of the only book to bring together all of these topics worldwide under one cover.

Aquaculture is currently one of the fastest growing production sectors in the world. It now accounts for nearly half (45%) of the worlds food fish (which refers to production of aquatic animals: fish, crustaceans, molluscs, amphibians) and this increase is expected to reach 50% in 2015. Genetic engineering and biotechnology have contributed vastly to this field. The most commonly used methods in fish biotechnology are chromosome manipulation and hormone treatment which can be used to produce triploid, tetraploid, haploid, gynogenetic and androgenetic fish.

A comprehensive study of pond fisheries. Topics include the organisation and construction of fish ponds, production processes in fish farms for warmwater carp and cold-water trout, and irrigation networks and reservoirs constructed for multipurpose exploitation.

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.

Understanding the Oceans brings together an internationally distinguished group of authors to consider the enormous advances in marine science that have been achieved since the voyages of HMS Challenger a century ago. The whole book draws inspiration from the seminal contribution made by the research conducted on those voyages, and each contributor considers the significance of the findings, relating them to the exciting developments of today and tomorrow. Covering the whole spectrum of the marine sciences, the book has been written and edited very much with the non-specialist reader in mind. Marine scientists, whether students or researchers, will welcome this authoritative sweep through the history of their subject through to the present day; other scientists will find the book to be an accessible and informative introduction to marine science and its historical roots.

This volume is an outcome of the annual meeting of the crustacean society symposia on Crustacean Issues 2. It examines issues in contemporary carcinology. The volume emphasises on larval and postlarval growth in decapods.

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.
