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.

The purposes of the present dictionary are to define the osteological and taxonomic terms referring to fishes, and to explain the rationale, both anatomical and function, of fish skeletal units, in an evolutionary and biological context. This branch of biology - fish osteology - provides a deeper insight into fish evolution, bone homologies, fish terminology, and fish taxonomy.

Ecologists sometimes have a less-than-rigorous background in quantitative methods, yet research within this broad field is becoming increasingly mathematical. Written in a step-by-step fashion, Fractals and Multifractals in Ecology and Aquatic Science provides scientists with a basic understanding of fractals and multifractals and the techniques for utilizing them when analyzing ecological phenomenon. With illustrations, tables, and graphs on virtually every page - several in color - this book is a comprehensive source of state-of-the-art ecological scaling and multiscaling methods at temporal and spatial scales, respectfully ranging from seconds to months and from millimeters to thousands of kilometers. It illustrates most of the data analysis techniques with real case studies often based on original findings. It also incorporates descriptions of current and new numerical techniques to analyze and deepen understanding of ecological situations and their solutions. Includes a Wealth of Applications and Examples This book also includes nonlinear analysis techniques and the application of concepts from chaos theory to problems of spatial and temporal patterns in ecological systems. Unlike other books on the subject, Fractals and Multifractals in Ecology and Aquatic Science is readily accessible to researchers in a variety of fields, such as microbiology, biology, ecology, hydrology, geology, oceanography, social sciences, and finance, regardless of their mathematical backgrounds. This volume demystifies the mathematical methods, many of which are often regarded as too complex, and allows the reader to access new and promising concepts, procedures, and related results.

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.

In this book, the authors examine the governance of marine protected areas (MPA), and in particular they compare two different forms of governance - co-management (CM) and adaptive co-management (ACM). CM is characterized by the decentralization of the decision-making process, incorporating the governed as well as the government. ACM is characterized by the dynamic process whereby co-management decision-making is made continuously responsive to the changing ecological and socio-economic circumstances of the MPA. The authors carry out a comprehensive critical analysis of CM and ACM before applying these concepts to the case study of the Cayos Cochinos Marine Protected Area off Honduras to assess two successive management cycles, 2004-9 and 2008-13. The area was designated as an MPA in 1993, a governmental decision which was met with resentment by local communities. CM was introduced in 2004 to involve these local stakeholders in the decision-making process, but achieved limited success. In an attempt to deal with these deficiencies, ACM was adopted in the second management plan in 2008, but whereas the position of the local communities improved, it tipped the scales too far away from conservation. A third management plan is currently being prepared that promises to strike a better balance between ecological and socio-economic objectives. A central theme of the book is to examine how far the CCMPA adhered to the principles of CM and ACM respectively in its first two management plans.

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.

Limnology provides an in-depth and current overview of the field of limnology. The result of a major tour de force by two renowned and experienced experts, this unique and richly illustrated reference presents a wealth of data on limnology history, water as a substrate, lakes' origins and aquatic biota. Besides a general part, it gives special focus to neotropical limnology, prevalently applicable in countries in the Southern Hemisphere. Starting with the essentials, some definitions and a historical account, this volume then details the main interaction mechanisms with physical and chemical factors, diversity and geographical distribution. With regard to the major continental aquatic systems, it treats the dynamics, variability and characterization of lakes, reservoirs, flooded areas, saline lakes, estuaries and coastal lagoons. The impact of human activity on water resources and the need for the rehabilitation of watersheds, watershed ecosystems and estuaries are addressed subsequently. To illustrate theory, the final part includes research examples in limnology, ecology and environmental sciences in different geographical contexts, as well as ideas for new investigations. This reference volume is intended for researchers and professionals working on inland waters, lakes and rivers within the fields of biology, ecology, environment, forestry, geochemistry, geophysics, and water management. It will also benefit students in the aforementioned areas and readers involved with limnology in related disciplines, such as earth sciences, environmental, water and geological engineering.

Recent Advances in Freshwater Crustacean Biodiversity and Conservation focuses on minor crustacean groups and regionally endemic groups, all from freshwaters. Chapters in this book cover crustaceans such as Maxillopods, Mysids, Cumaceans, Isopods, Amphipods, Branchiopods, Copepods, and Decapods. Each looks at global or regional fauna and discusses conservation issues for that group. The majority of the chapters are based on papers presented at symposia organized by the editors at two international scientific meetings held in Barcelona and Washington DC. The contributors are world-renowned experts on their groups, as well as on freshwater crustacean conservation and biodiversity at global levels. It has previously been difficult for conservation managers, NGOs, and university professors and students who may not have access to comprehensive journal subscriptions to find relevant information on diversity and conservation of freshwater crustaceans. This book meets that need, addressing crustacean groups not previously treated and providing additional information beyond any presented in existing books. As the editors write in their introduction: we cannot conserve and we cannot protect what we do not know exists. This is a reliable, cutting-edge reference for anybody involved in crustacean research: students, researchers, agencies, and NGOs, as well as science educators, conservationists, and government conservation policymakers. The book will also be useful for those working in aquaculture and fisheries, given that many of the taxa discussed are economically important.

In anticipation of the UN Conference of the Law of the Sea taking place in 1973, Dr Kasahara and Dr Burke of the University of Washington first published North Pacific Fisheries Management earlier that year. The conference brought fishery territories to a global stage with delegates that may not be as informed about ocean issues as those previously making decisions. Therefore the Program of International Studies of Fishery Arrangements was created to explore the management of fisheries in specific regions. This study focusses on the North Pacific region and delves into the implications of a global regime, generic problems concerning fishery management, distribution and institutions as well as alternative arrangements that can be made to make the management of fisheries smoother. This title will be of interest to students of environmental studies and policy makers.

This book should be of interest to seafood processors, fish scientists, R & D personnel in the food processing industry, importers and exporters.

Tropical estuaries are among the most modified and threatened of aquatic environments, supporting innumerable fisheries essential to the regions in which they occur. This book synthesizes the wealth of data available in this area, much of it being brought together by Stephen Blaber for the first time. It will provide readers with a comprehensive understanding of the fishes, the environments in which they live, and the management of biologically healthy estuaries and sustainable fisheries.

The Multilingual Illustrated Dictionary of Aquatic Animals and Plants provides a unique reference to the names of 1532 species of fish, crustaceans, molluscs, seaweeds and other fishery products that are landed worldwide. The names of these species can vary significantly between neighbouring regions of a country, from the size of the fish, from the stage of its life cycle, from the season of the year, and from its degree of treatment after capture. Co--published by the European Commission and Fishing News Books, the Multilingual Illustrated Dictionary of Aquatic Animals and Plants seeks to address this problem and to eliminate much of the existing confusion. New to the Second Edition of this acclaimed Dictionary is the addition of Finnish and Swedish to each existing entry. The Dictionary has been expanded to include new species and illustrations. For each entry, the following information is given: Reference number (the number given to the species within the index); Scientific (Latin) name; Family name; English name; Dutch name; French name; Danish name; German name; Greek name; Italian name; Portuguese name; Spanish name; Finnish name; Swedish name. Comprehensively illustrated, the New Second Edition of the multilingual Illustrated Dictionary of Aquatic Animals and Plants is an essential reference for all involved in the commercial fishing industries both within and beyond the boundaries of the European Union

After many "out-of-print" years, this volume has been reissued in response to an increasing demand for copies. This reflects that the fundamental questions that motivated this book thirty years ago are still being asked. But more important, the answers -- or at least their outlines -- now seem to be in sight. In 1968, this book stood as an expression of a paradigm crisis in its critique of the state of personality psychology. The last three decades have been filled with controversy and debate about the dilemmas raised here, and then with renewal and fresh discoveries. It therefore seems especially timely to revisit the pages which posed the challenges. Mischel outlined the need to encompass the situation in the study of personality, but with a focus on the acquired meaning of stimuli and on the situation as perceived, viewing the individual as a cognitive-affective being who construes, interprets, and transforms the stimulus in a dynamic reciprocal interaction with the social world. He focused on the idiographic analysis of personality that had originally motivated the field, and the complexity, discriminative facility, and uniqueness of the individual, and sought to connect the expressions of personality to the individual's behavior -- that is, to what people do and not just what they say. Even the intrinsically contextualized "if...then..." expressions of the personality system -- its essential behavioral signatures -- were foreshadowed in this book that fired the opening salvo in a search for "a truly dynamic personality psychology."

First Published in 1968. This works seeks to be neither controversial nor polemical, the author intends to present an entirely objective account of the beliefs and institutions of Islam. Lammens describes Hejaz as the cradle of Islam, where Western Arabia in its mountainous complexity holds as the primary focus in this title. Discussing Islam as having been formed by the evolution of thirteen centuries, the details supplied within enable the reader to extensively follow its historical development.

This book provides new information on how various inclusion policies have been implemented in different schools and school districts in North America and in a range of European countries. The purpose of inclusion policy is to prevent the marginalization of people who experience unfavorable circumstances in life. It is an approach to the education of students with disabilities that is based on a commitment to what all members of a free society deserve in order to become fully participating members--a fair chance to find a meaningful place in their own communities. This book is a kind of status report on what inclusive education has achieved and what it may achieve in the future for children and youth with disabilities. It describes the philosophical, legal, and practical terrain covered by inclusion policy in general and inclusive schooling in particular. Contributors assess inclusion policy and suggest ways to reconceptualize it, bringing to their data analysis a depth of experience and knowledge about public schooling in their respective countries. Although inclusion of students with disabilities in general education classes has been embraced by politicians and educators calling for equal opportunity in our society and is being incorporated into national and international education laws, it continues to be controversial and the debate is sometimes heated. A goal of this book is to shed some light on this debate. Is inclusion mostly about student placement? Are students with disabilities attaining social and learning membership in general classrooms? Have they benefitted from inclusion? How about students without disabilities? What have been the benefits? Must learning take second priority to socialization and friendship? Are teachers getting the training they need? How do parents feel about inclusion programs? How do students feel? What kind of curricular accommodations should be made? These and other questions are addressed. This volume is based on original papers presented by the contributing authors in October 1997 at the Rutgers Invitational Symposium on Education on Inclusive Schooling: National and International Perspectives.

Anguillid eels have fascinated biologists for centuries due to their spectacular long-distance migrations between freshwater habitats and their spawning areas far out in the ocean. This book provides a long overdue update on the biology and ecology of anguillid eels and features comprehensive coverage of the key features of the genus Anguilla. It covers a broad spectrum of topics on the biology (taxonomy, phylogeny, evolution, reproduction, feeding, salinity adaptation) and ecology (life history, recruitment, migration) of anguillid eels. It also brings together important information on the state of eel fisheries, conservation, exploitation, and management.

In recent years the subject of pollution of natural waters by aquaculture has received considerable attention. With increasingly stringent regulation of wastewater quality from fish farms around the world, those involved in the industry need to be aware of the causes of pollution from fish and shellfish farms and of methods by which this pollution may be prevented. This book aims to bring the principles of wastewater treatment and other pollution control techniques for fish and shellfish farming to a wide audience of farmers, students, scientists and engineers; in fact anyone who works in aquaculture or pollution control. For this reason, the authors who have between them much experience in this area have written this important book with both the specialist and those new to the area in mind. As part of the growing Aquaculture Series, this title gives a comprehensive insight into this topic of vital importance to the aquaculture industry. This book should be on the shelves of all those involved in fish and shellfish farming and connected environmental issues, and available in universities and research establishments for students and professionals alike.
