Book Synopsis A Global Assessment of Fisheries Bycatch and Discards by : Dayton L. Alverson
Download or read book A Global Assessment of Fisheries Bycatch and Discards written by Dayton L. Alverson and published by Food & Agriculture Org.. This book was released on 1994 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors estimate that between 17.9 and 39.5 million tons (average 27.0 million) of fish are discarded each year in commercial fisheries. These estimates are based on a review of over 800 papers. The highest quantities of discards are from the Northwest Pacific while tropical shrimp trawl fisheries generate a higher proportion of discards than any other fishery type, accounting for one third of the global total. Of four major gear groups, shrimp trawls stand alone at the top of the list; bottom trawls, long-lines and pot fisheries come next. The third group consists of Japanese high-seas drift net fisheries, Danish seines and purse seines for capelin. Relatively low levels result from pelagic trawls, small pelagic purse seines and some of high seas drift nets. The authors point to inadequate data to determine the biological, ecological, economic and cultural impacts of discards although economic losses run to billions of dollars. However, it appears most likely that socio-cultural attitudes towards marine resources will guide international discard policies. Techniques to reduce bycatch levels including traditional net selectivity, fishing gear development and time/area restrictions, are discussed. Effort reduction, incentive programmes and individual transferable quotas (that make the vessel responsible for bycatch reduction) are seen as promising avenues for the future. However, quick solutions to the problem are unlikely and much more information is required. The publication includes a diskette with the complete Bycatch Database, which was compiled for the study, and a summary of it.

Book Synopsis Pacific Salmon Life Histories by : Cornelis Groot
Download or read book Pacific Salmon Life Histories written by Cornelis Groot and published by UBC Press. This book was released on 1991 with total page 602 pages. Available in PDF, EPUB and Kindle. 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.
Download or read book Haa Aaní written by Walter Goldschmidt and published by University of Washington Press. This book was released on 1998 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 1940s, a boom in white migration to Southeast Alaska brought up questions of land and resource rights. In 1946, the Commissioner of Indian Affairs assigned a team of researchers to interview old and young villagers to discover who owned and used the lands and waters of the region and under what rules. Their report is published here for the first time in book form, along with text of interviews with 88 natives, a reminiscence by an anthropologist on the research team, and an introduction explaining the context and significance of the original report.
