The ECNASAP Pilot Project consists of inshore and offshore case studies, and is a cooperative effort among several U.S. and Canadian agencies. Digital map and data products are being developed in the Offshore Case Study for groundfish, seabirds, temperature, salinity, and sediments. This report summarizes the initial results for the groundfish component. About Partitioning the Total Mortality of Atlantic Cod Stocks Project In 1995, Canada's Department of Fisheries and Oceans (DFO) initiated a series of research projects to address high priority issues for the Atlantic and Pacific coasts. The Cod Mortality Project is a component of this effort; its objective is to assess the main causes for the decline of cod resources since the mid-1980s. A subproject is to examine long-term changes in groundfish assemblages on a biogeographic scale, and to determine whether or not these changes coincided with changes in ocean climate.

  • Early Stages of Fishes in the Western North Atlantic Ocean Volume
    ISBN 0-9689167-4-x Early Stages of Fishes in the Western North Atlantic Ocean (Davis Strait, Southern Greenland and Flemish Cap to Cape Hatteras) Volume One Acipenseriformes through Syngnathiformes Michael P. Fahay ii Early Stages of Fishes in the Western North Atlantic Ocean iii Dedication This monograph is dedicated to those highly skilled larval fish illustrators whose talents and efforts have greatly facilitated the study of fish ontogeny. The works of many of those fine illustrators grace these pages. iv Early Stages of Fishes in the Western North Atlantic Ocean v Preface The contents of this monograph are a revision and update of an earlier atlas describing the eggs and larvae of western Atlantic marine fishes occurring between the Scotian Shelf and Cape Hatteras, North Carolina (Fahay, 1983). The three-fold increase in the total num- ber of species covered in the current compilation is the result of both a larger study area and a recent increase in published ontogenetic studies of fishes by many authors and students of the morphology of early stages of marine fishes. It is a tribute to the efforts of those authors that the ontogeny of greater than 70% of species known from the western North Atlantic Ocean is now well described. Michael Fahay 241 Sabino Road West Bath, Maine 04530 U.S.A. vi Acknowledgements I greatly appreciate the help provided by a number of very knowledgeable friends and colleagues dur- ing the preparation of this monograph. Jon Hare undertook a painstakingly critical review of the entire monograph, corrected omissions, inconsistencies, and errors of fact, and made suggestions which markedly improved its organization and presentation.

  • An Annotated Bibliography of Diet Studies of Fish of the Southeast United States and Gray’S Reef National Marine Sanctuary
    Marine Sanctuaries Conservation Series MSD-05-2 An annotated bibliography of diet studies of fish of the southeast United States and Gray’s Reef National Marine Sanctuary U.S. Department of Commerce February 2005 National Oceanic and Atmospheric Administration National Ocean Service Office of Ocean and Coastal Resource Management Marine Sanctuaries Division About the Marine Sanctuaries Conservation Series The National Oceanic and Atmospheric Administration’s Marine Sanctuary Division (MSD) administers the National Marine Sanctuary Program. Its mission is to identify, designate, protect and manage the ecological, recreational, research, educational, historical, and aesthetic resources and qualities of nationally significant coastal and marine areas. The existing marine sanctuaries differ widely in their natural and historical resources and include nearshore and open ocean areas ranging in size from less than one to over 5,000 square miles. Protected habitats include rocky coasts, kelp forests, coral reefs, sea grass beds, estuarine habitats, hard and soft bottom habitats, segments of whale migration routes, and shipwrecks. Because of considerable differences in settings, resources, and threats, each marine sanctuary has a tailored management plan. Conservation, education, research, monitoring and enforcement programs vary accordingly. The integration of these programs is fundamental to marine protected area management. The Marine Sanctuaries Conservation Series reflects and supports this integration by providing a forum for publication and discussion of the complex issues currently facing the National Marine Sanctuary Program. Topics of published reports vary substantially and may include descriptions of educational programs, discussions on resource management issues, and results of scientific research and monitoring projects. The series facilitates integration of natural sciences, socioeconomic and cultural sciences, education, and policy development to accomplish the diverse needs of NOAA’s resource protection mandate.

Address correspondence to W. L. Smith at the address above, or e-mail: [email protected]. Abstract Knowledge of evolutionary relationships or phylogeny allows for effective predictions about the unstudied characteristics of species. These include the presence and biological activity of an organism’s venoms. To date, most venom bioprospecting has focused on snakes, resulting in six stroke and cancer treatment drugs that are nearing U.S. Food and Drug Administration review. Fishes, however, with thousands of venoms, represent an untapped resource of natural products. The first step in- volved in the efficient bioprospecting of these compounds is a phylogeny of venomous fishes. Here, we show the results of such an analysis and provide the first explicit suborder-level phylogeny for spiny-rayed fishes. The results, based on ;1.1 million aligned base pairs, suggest that, in contrast to previous estimates of 200 venomous fishes, .1,200 fishes in 12 clades should be presumed venomous.

The actinian type species, Stylobates aeneus, first assigned to the Mollusca, occurs around Hawaii and Guam with P. dofleini.
