Download or read book The Fishery for Scup with Special Reference to Fluctuations in Yield and Their Causes written by William C. Neville and published by . This book was released on 1963 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The catch of scup over the past 50 years has fluctuated widely. Data on this fishery for recent years (1922-35), obtained from State and Federal agencies, commercial fishery, and fishermen, have been analysed to determine causes of fluctuations. It was found that fluctuations in the summer fishery from New Jersey to Massachusetts were caused mainly by differences in the size of the successive year classes entering the fishery. Fluctuations in the catch of the winter trawl fishery off the Virginia Capes resulted from changes in the amount of cooling of the bottom water where these fish are found in winter. During cold-water conditions, the fish became more concentrated and were more easily caught; whereas, when the water was warmer, the fish scattered more widely and were not as readily available. Although fluctuations in catch of the summer and winter fishery have different causes, results of tagging and observations of size composition have disclosed that both fisheries draw on the same general stock.

Available in PDF, EPUB and Kindle. Book excerpt: In Nature's Entrepot, the contributors view the planning, expansion, and sustainability of the urban environment of Philadelphia from its inception to the present. The chapters explore the history of the city, its natural resources, and the early naturalists who would influence future environmental policy. They then follow Philadelphia's growing struggles with disease, sanitation, pollution, sewerage, transportation, population growth and decline, and other byproducts of urban expansion. Later chapters examine efforts in the modern era to preserve animal populations, self-sustaining food supplies, functional landscapes and urban planning, and environmental activism. Philadelphia's place as an early seat of government and major American metropolis has been well documented by leading historians. Now, Nature's Entrepot looks particularly to the human impact on this unique urban environment, examining its long history of industrial and infrastructure development, policy changes, environmental consciousness, and sustainability efforts that would come to influence not just this region but also the nation.
