Book Description
Water Quality Criteria for Freshwater Fish, Second Edition, is a collection of 12 technical papers on water quality criteria for European freshwater fish, together with a report on fish toxicity testing procedures that have been produced for the European Inland Fisheries Advisory Commission (EIFAC)—an intergovernmental organization with a current membership of 24 countries. Each chapter reviews a particular water quality characteristic for European inland fisheries, although the effects of mixtures with other harmful substances have been described for some of them. These characteristics include water quality criteria for finely suspended solids and pH values; water temperature; the effect of ammonia; phenolic wastes; dissolved oxygen; chemistry and toxicology of chlorine; and toxicity of zinc, copper, and cadmium. The reports in this volume will be useful not only to the member countries of the European Inland Fisheries Advisory Commission, but also to those concerned with the management of inland waters and their fishery resources in other continents.

Book Description
Marine aquariums is a fast-growing hobby, and with today's technology, creating a thriving marine or reef aquarium is easier than ever. In Complete Book of the Freshwater Aquarium, hundreds of dramatic underwater photographs provide a fish's-eye view of 700 species of sea creatures while accessible scientific text explains the reef's fragile ecosystem. Written by an expert aquarist and diving enthusiast, this book also features a comprehensive guide to creating a home aquarium, from setting up the environment to selecting equipment, fish and invertebrates. Diving into this book will thrill both the advanced aquarist and the novice.

Book Description
This volume is of great importance to humans and other living organisms. The study of water quality draws information from a variety of disciplines including chemistry, biology, mathematics, physics, engineering, and resource management. University training in water quality is often limited to specialized courses in engineering, ecology, and fisheries curricula. This book also offers a basic understanding of water quality to professionals who are not formally trained in the subject. The revised third edition updates and expands the discussion, and incorporates additional figures and illustrative problems. Improvements include a new chapter on basic chemistry, a more comprehensive chapter on hydrology, and an updated chapter on regulations and standards. Because it employs only first-year college-level chemistry and very basic physics, the book is well-suited as the foundation for a general introductory course in water quality. It is equally useful as a guide for self-study and an in-depth resource for general readers.

Book Description
"This timely volume brings together recent critical reviews on water quality requirements for freshwater fish commissioned by the European Inland Fisheries Advisory Commission, an agency of the United Nations Food and Agriculture Organisation. It provides a unique and authoritative source of critically evaluated water quality data concerning the effects of chromium, nickel, aluminium and nitrite on freshwater fish and includes an assessment of the toxicity of mixtures. The reports presented in this volume cover all stages of the life cycle and relevant trophic levels, including aquatic invertebrates and plants and potential bioaccumulation through the food chain. An extensive bibliography is provided for each chapter as well as a glossary of terms and list of fish species mentioned in the text. This compilation of papers is the definitive reference volume for chemists, biologists, ecologists and toxicologists as well as for water resource managers concerned with management and control of pollution in fresh waters."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Book Description
Annotation Aquaculture provides an attractive alternative to capture fisheries where the majority of species are overexploited and an increased yield potential is unlikely. This document reviews the standards for water and fish product quality, looks at the parameters of greatest importance to aquaculture, and discusses the scientific basis for these standards. Containing information from current literature and government standards, it provides practical, cost-effective guidelines to determine whether the quality of the proposed source water will present a significant risk to the success of a project.

Book Description
For beginning aquatic fancier looking to start out right with fish, Freshwater Aquariums by David Alderton is the ideal primer. A vertebrate that breathe primarily by means of gills and swim by means of fins is the author’s lead-in to the first chapter called “What are Fish?” Alderton builds the reader’s confidence by providing solid information about what fish are anatomically speaking, how they evolved, how they breathe, how they move, where they live, and how they behave. The new fancier’s aquarium begins in chapter two with instructions on setting up the tank, including selecting the right size, figuring out how many fish, setting the tank, equipment, substrate, heating, lighting, filtrations, plants, water chemistry, assembly, and more. Choosing the freshwater fishes that appeal to the reader is the subject of “Introducing the Categories of Fish,” which schools readers in seven categories: Cyprinids (e.g., goldfish, minnows, and barbs), Characins (e.g., tetras), Cichlids (e.g., oscars, angelfish, and discus), Anabantoids (gouramis, bettas/Siamese fighting fish, and paradise fish), Toothcarps (guppies, swordtails, platies, black mollies, and killifish), Catfish, and others (loaches and Chinese algae eaters). The purchasing, maintenance, and feeding of fish are described in considerable details, and the author gives a basic overview of breeding and keeping fish healthy as well. Resources, glossary, and index conclude the book.

Book Description
The efficient and profitable production of fish, crustaceans, and other aquatic organisms in aquaculture depends on a suitable environment in which they can reproduce and grow. Because those organisms live in water, the major environ mental concern within the culture system is water quality. Water supplies for aquaculture systems may naturally be oflow quality or polluted by human activity, but in most instances, the primary reason for water quality impairment is the culture activity itself. Manures, fertilizers, and feeds applied to ponds to enhance production only can be partially converted to animal biomass. Thus, at moderate and high production levels, the inputs of nutrients and organic matter to culture units may exceed the assimilative capacity of the ecosystems. The result is deteriorating water quality which stresses the culture species, and stress leads to poor growth, greater incidence of disease, increased mortality, and low produc tion. Effluents from aquaculture systems can cause pollution of receiving waters, and pollution entering ponds in source water or chemicals added to ponds for management purposes can contaminate aquacultural products. Thus, water quality in aquaculture extends into the arenas of environmental protection and food quality and safety. A considerable body of literature on water quality management in aquaculture has been accumulated over the past 50 years. The first attempt to compile this information was a small book entitled Water Quality in Warmwater Fish Ponds (Boyd I 979a).

Book Description
This classroom resource provides clear, concise scientific information in an understandable and enjoyable way about water and aquatic life. Spanning the hydrologic cycle from rain to watersheds, aquifers to springs, rivers to estuaries, ample illustrations promote understanding of important concepts and clarify major ideas. Aquatic science is covered comprehensively, with relevant principles of chemistry, physics, geology, geography, ecology, and biology included throughout the text. Emphasizing water sustainability and conservation, the book tells us what we can do personally to conserve for the future and presents job and volunteer opportunities in the hope that some students will pursue careers in aquatic science. Texas Aquatic Science, originally developed as part of a multi-faceted education project for middle and high school students, can also be used at the college level for non-science majors, in the home-school environment, and by anyone who educates kids about nature and water.
