Survival in Toxic Environments is a collection of papers presented at a symposium held in Houston, Texas, in December 1973 and organized by the American Society of Zoologists, Division of Comparative Physiology and Biochemistry. Contributors focus on chemical pollutants, as well as the pollutants' fate and disposition in the environment and bio-environmental effects. The specific pollutants and/or toxicants include pesticides, crude and refined oils, polychlorinated biphenyls, polycyclic aromatic hydrocarbons, nitrilotriacetic acid, lead, carbon monoxide, and other supposedly less ominous xenobiotics. The dispositions of these substances and their effects are examined in either ecosystems and/or organisms, or components thereof. This volume is organized into five sections encompassing 21 chapters and begins with an overview of chemicals, how they are degraded, and how they affect living organisms. The first section discusses the impact of chemical pollutants, such as DDT, on the biology of organisms. The second section explores the detoxication mechanisms of survival in toxic environments, emphasizing halogenated hydrocarbons and their fate in microbes, houseflies, and fish. The reader is then methodically introduced to the role of the mixed-function oxidase and its components in survival in toxic environments, along with the trends in pesticide research. The final section considers non-pesticidal pollutants, such as NTA (a detergent builder), lead, and carbon monoxide, and their secondary effects. This book will be of interest to scientists and researchers in fields such as chemical pharmacology, chemical pathology, biology, zoology, ecology, agricultural chemistry, and entomology.

Centrarchid fishes, also known as freshwater sunfishes, include such prominent species as the Largemouth Bass, Smallmouth Bass and Bluegill. They are endemic to Eastern North America where they form part of a multi-million dollar sports fishing industry, but they have also been widely introduced around the globe by recreational anglers, in aquaculture programs and by government fisheries agencies. Centrarchid Fishes provides comprehensive coverage of all major aspects of this ecologically and commercially important group of fishes. Coverage includes diversity, ecomorphology, phylogeny and genetics, hybridization, reproduction, early life history and recruitment, feeding and growth, ecology, migrations, bioenergetics, physiology, diseases, aquaculture, fisheries management and conservation. Chapters have been written by well-known and respected scientists and the whole has been drawn together by Professors Cooke and Philipp, themselves extremely well respected in the area of fisheries management and conservation. Centrarchid Fishes is an essential purchase for all fish biologists, ecologists, fisheries managers and fish farm personnel who work with centrarchid species across the globe.

It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.

This book focuses exclusively on the beneficial effects of microbes in food. The section on traditional and modern fermented foods covers the role of microbes and their diversity in fermented foods, interaction between the different microflora present in fermented food products, development of starter cultures to improve the nutritional and sensory quality of fermented foods, and factors and processes affecting the safety of various fermented foods. The second section focuses on microbes in and as functional foods: probiotics, prebiotics and synbiotics.
