Captive Seawater Fishes: Science and Technology Stephen Spotte "The book is clearly a labor of love, and one must admire the author's boundless enthusiasm and breadth of scholarship." —New Scientist A seamlessly clear treatise on the science and technology of maintaining seawater fishes for purposes of aquaculture and public exhibition. Captive Seawater Fishes is the first book to bring together in one volume the disciplines of seawater chemistry, process engineering, and fish physiology, behavior, nutrition, and health. Richly illustrating the interplay between living fishes and the chemical and sensory stimuli of their environment, the book details: chemical processes controlling carbonate stability in seawater; the effect of captivity on physiological processes; sensory processes of fishes, including vision, hearing, and electroreception; diseases of seawater fishes and treatment methods; and more. 1991 (0-471-54554-6) 976 pp. Surveys of Fisheries Resources Donald R. Gunderson The intensive exploitation of fisheries resources has heightened the reliance in the industry on statistical surveying as a means of monitoring the abundance and age composition of existing fish reserves. Here is the first comprehensive look at the unique challenges and problems of fisheries surveying. Covering everything from survey design, bottom trawl surveys, acoustic surveys, to egg and larval surveys and direct counts, as well as the assumptions and limitations surrounding each method, the book is an exhaustive, yet practical guide to designing accurate, cost-effective fisheries surveys. 1993 (0-471-54735-2) 256 pp. Aquatic Pollution: An Introductory Text, Second Edition Edward A. Laws Regarded as the most complete introduction available on the subject, Aquatic Pollution details the ecological principles and toxicological fundamentals behind the phenomenon as well as the latest information on the factors affecting our polluted aquatic environment. Featuring case studies and specific examples, the book systematically examines such problems as urban runoff, sewage disposal, thermal pollution, nutrient loading, industrial wastewater discharges, and oil pollution. The new Second Edition includes three new chapters on groundwater pollution. acid rain, and plastics in the sea, as well as updated and expanded information on eutrophication, pathogens in water supplies, radioactive waste disposal, toxic metals, and pesticide use. 1993 (0-471-58883-0) 611 pp.

The Handbook on small-scale freshwater fish farming provides a wealth of simply presented and illustrated information on freshwater fish farming in ponds, pens and cages, compiled form five booklets published on the subject in FAO s Better Farming Series between 1979 and 1990. Here is an improved format, particulars of pond, pen and cage location, construction and management are covered in outlines that can be modified to suit local conditions. The handbook is primarily intended to help workers, technicians and teachers present their knowledge of freshwater fish farming to small-scale farmers. For example, it can be used as a trainers aid in conjunction with the five original booklets, which can be distributed among trainees. The handbook ends with a set of questions that could be used to tests the trainees comprehension.

Ponds are a primary production system to a wide variety of freshwater fish species. Each species have specific and unique nutrient needs and successful pond fertilization is critical to a successful aquaculture enterprise. Aquaculture Pond Fertilization: Impacts of Nutrient Input on Production provides state-of-the-art information for successful fertilization strategies for a broad range of pond-raised species. Aquaculture Pond Fertilization attempts to rectify the seemingly contradictory nutrient recommendations by clearly defining the goals of specific types of aquaculture. Chapters are divided into three sections: The first reviews basic concepts in fertilization applicable to all pond-based production. The second looks at specific nutrient management approaches. The third and final section of chapters looks specifically at key freshwater pond species ranging from tilapia to perch and discusses specific fertilization needs for the successful rearing of these in-demand fish. Looking across species with chapters contributed by leaders in the field Aquaculture Pond Fertilization provides succinct single-volume coverage of an oft-neglected, but vitally important topic in aquaculture production.

Small pelagic fish species found in lakes and introduced to reservoirs dominate by volume and contribute some of the most important inland fisheries in Africa with steadily increasing catches and additional potential. This circular reviews the status and importance of the pelagic fish and fisheries, together with small fish in general, for sustainable and healthy livelihoods in Africa. It reviews the biology and biological production of the most important pelagic species in lakes and reservoirs as well as the impacts of environmental and climatic variation on the stocks of these species. It examines and discuss the various capture techniques together with potential of improvements in the fisheries and associated processing and national and regional trade within Africa. The knowledge generated by the circular will be useful for policy makers and development practitioners to design and implement more effective policies, strategies and programs that will contribute to reducing the food insecurity and conflicts that currently affect the people in sub-Saharan Africa.
