Available in PDF, EPUB and Kindle. Book excerpt: The blue crab (Callinectes sapidus Rathbun) of the Atlantic and Gulf coasts supports the largest crab fishery in the United States. Chesapeake Bay on the Atlantic coast and the estuarine waters of Louisiana on the Gulf coast now furnish 75 percent of the catch. Fluctuations in the abundance of blue crabs have occurred over the past half century in Chesapeake Bay where year-round fisheries have long been established. This report examines the nature and causes of fhese fluctuations. Several natural factors which appear to regulate the annual survival rate and the abundance of the blue crab are discussed on the basis of available knowledge.

Download or read book Fishery Management written by J.L. McHugh and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several textbooks and useful compendia on fisheries have been published recently, and others are in preparation. The question then arises: why publish another book on fisheries at this time? My answer is 1) that fishery research and management are such broad subjects that it is difficult, if not impossible, to cover them adequately in one volume; 2) that consequently each author has stressed those aspects of greatest immediate interest to him; and 3) that to the best of my knowl edge no adequate broad treatment of the sociopolitical aspects of fishery management has yet ·appeared, although some good discussions have been published for particular fisheries. This volume grew out of a course that I have taught for the last 12 years at the State University of New Yo·rk at Stony Brook. Originally, the title of the course was Fishery Ecology, which was a matter of surprise to some students when they attended the fi rst few 1 ectures. Despite the sudden recent emergence of ecology as a household word, most people do not understand what the term means. I have found that even some graduate students forget that man is a potent force in the dynamic state of aquatic life. This is not only because he does things that change the environment and so affects living things in it, but also because he has such strange ways of thinking and of managing his affairs.
