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.
Advances in Food-Producing Systems For Arid and Semiarid Lands Part B by Jamal Manassah Pdf
Advances in Food-Producing Systems for Arid and Semiarid Lands: Part B contains the proceedings of a symposium on ""Advances in Food-Producing Systems for Arid and Semiarid Lands"" of the International Symposium Series held in Kuwait in April 1980. As a continuation of the proceedings, this compilation contains the last three parts of the symposium and the editor's closing remarks. It specifically talks about the innovative food systems and aquacultural systems in the arid and semi-arid lands. It also addresses the general problems of post-harvest losses in food of plant origin and the possibilities to reduce these losses. The presented papers bring renewed vitality to the hope that appropriate and directed exploitation of various technologies can evolve developable industries for arid and semiarid lands.
