Fifteen years in the making, this updated edition raises the high standard of Bigelow and Schroeder's 1953 reference by drawing from a much larger base of information. Thirty-eight experts in fisheries biology and ichthyology clearly distill the enormous amount of knowledge gained during the past fifty years, including distribution figures from thirty years of annual trawl surveys; food habit accounts from surveys of the stomach contents of more than 30,000 fishes; and egg distribution data from a survey exceeding 10,000 samples. The contributors update Bigelow and Schroeder's 1953 material while presenting a wealth of new information, including thirty-three additional species accounts. By adding fifty percent more material and focusing the volume on data, the editors address the needs of today's biologists, the commercial fishing industry, and marine enthusiasts, and ensure that Bigelow and Schroeder's Fishes of the Gulf of Maine, Third Edition, will become the standard work in the field for the next fifty years.

This book is open access under a CC BY-NC 2.5 license. The Gulf of Mexico is an open and dynamic marine ecosystem rich in natural resources but heavily impacted by human activities, including agricultural, industrial, commercial and coastal development. The Gulf of Mexico has been continuously exposed to petroleum hydrocarbons for millions of years from natural oil and gas seeps on the sea floor, and more recently from oil drilling and production activities located in the water near and far from shore. Major accidental oil spills in the Gulf are infrequent; two of the most significant include the Ixtoc I blowout in the Bay of Campeche in 1979 and the Deepwater Horizon Oil Spill in 2010. Unfortunately, baseline assessments of the status of habitats and biota in the Gulf of Mexico before these spills either were not available, or the data had not been systematically compiled in a way that would help scientists assess the potential short-term and long-term effects of such events. This 2-volume series compiles and summarizes thousands of data sets showing the status of habitats and biota in the Gulf of Mexico before the Deepwater Horizon Oil Spill. Volume 2 covers historical data on commercial and recreational fisheries, with an analysis of marketing trends and drivers; ecology, populations and risks to birds, sea turtles and marine mammals in the Gulf; and diseases and mortalities of fish and other animals that inhabit the Gulf of Mexico.

At least 162 species of fish are known to live or spawn in the freshwaters of the Northeast, representing twenty-eight families and sixteen orders. This diversity springs from an enormous variety of freshwater habitats, including some of the largest lakes in the world; vast and complex river systems; deep, clear lakes in Maine and the Adirondack Mountains; and myriad small lakes, bogs, marshes, and streams that dot the northeast. In the most comprehensive book of its kind, Robert G. Werner offers a thorough survey and analysis, in accessible field guide form, of the region's abundant freshwater fishes. Werner's discussion of the geological history of the region serves as a critical background for understanding not only the fascinating habitats of fishes but also the extensive watersheds and drainages of the region. A reference list provides up-to-date sources, and the species descriptions contain the latest relevant data and research on specific fish. In addition, vivid color plates and extensive line drawings illustrate fish morphology and the distinctive natural colors of numerous species. As a standard resource, this guide will attract a wide audience. This book will be useful to biologists, ecologists, and zoologists and will have an indispensable appeal among anglers, environmentalists, and fisheries professionals.

Because of the pervasive and substantial decline of Atlantic salmon populations in Maine over the past 150 years, and because they are close to extinction, a comprehensive statewide action should be taken now to ensure their survival. The populations of Atlantic salmon have declined drastically, from an estimated half million adult salmon returning to U.S. rivers each year in the early 1800s to perhaps as few as 1,000 in 2001. The report recommends implementing a formalized decision-making approach to establish priorities, evaluate options and coordinate plans for conserving and restoring the salmon.

Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.
