Book excerpt: Pacific salmon are an important biological and economic resource of countries of the North Pacific rim. They are also a unique group of fish possessing unusually complex life histories. There are seven species of Pacific salmon, five occurring on both the North American and Asian continents (sockeye, pink, chum, chinook, and coho) and two (masu and amago) only in Asia. The life cycle of the Pacific salmon begins in the autumn when the adult female deposits eggs that are fertilized in gravel beds in rivers or lakes. The young emerge from the gravel the following spring and will either migrate immediately to salt water or spend one or more years in a river or lake before migrating. Migrations in the ocean are extensive during the feeding and growing phase, covering thousands of kilometres. After one or more years the maturing adults find their way back to their home river, returning to their ancestral breeding grounds to spawn. They die after spawning and the eggs in the gravel signify a new cycle. Upon this theme Pacific salmon have developed many variations, both between as well as within species. Pacific Salmon Life Histories provides detailed descriptions of the different life phases through which each of the seven species passes. Each chapter is written by a scientist who has spent years studying and observing a particular species of salmon. Some of the topics covered are geographic distribution, transplants, freshwater life, ocean life, development, growth, feeding, diet, migration, and spawning behaviour. The text is richly supplemented by numerous maps, illustrations, colour plates, and tables and there is a detailed general index, as well as a useful geographical index.

Book excerpt: 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.

This book was released on 2012-12-06 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until the First Edition of World Fish Farming: Cultivation and Econom ics was published several years ago, there was little or no economic and technical information on commercial aquaculture either by countries or by species. I tried at that time to partially fill the gap in the literature. In this Second Edition, I have updated data originally presented and increased the scope by adding new countries. New trout data have been added for 10 western European countries; sections on cost of production of food-sized catfish and fingerlings in the USA; new and improved chapters for Japan, Hungary, Indonesia, the Philippines, and the United Kingdom; and com pletely new chapters pertaining to Poland, Thailand, and Czechoslovakia have all been added to this edition. The book now includes 31 countries, including all major producing ones. Between 5. 5 and 6. 0 million metric tons of finfish, shrimp, and crayfish cultured production are represented, which accounts for about 909c of the world's total. The People's Republic of China and the USSR, as well as countries on the continents of Europe, Asia, North America, and Oceania, are represented. Because of only minimal reported cultured fish production in Africa and South America, these continents have been omitted. Also, according to information received from New Zealand, there is no culturing offish in that country other than for restocking of public waters. More than 100 species of cultured fish, seven species of shrimp and prawns, and six species of crayfish are discussed.
