  • 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.

  • Environmental Sensitivity Index Guidelines Version 2.0
    NOAA Technical Memorandum NOS ORCA 115 Environmental Sensitivity Index Guidelines Version 2.0 October 1997 Seattle, Washington noaa NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION National Ocean Service Office of Ocean Resources Conservation and Assessment National Ocean Service National Oceanic and Atmospheric Administration U.S. Department of Commerce The Office of Ocean Resources Conservation and Assessment (ORCA) provides decisionmakers comprehensive, scientific information on characteristics of the oceans, coastal areas, and estuaries of the United States of America. The information ranges from strategic, national assessments of coastal and estuarine environmental quality to real-time information for navigation or hazardous materials spill response. Through its National Status and Trends (NS&T) Program, ORCA uses uniform techniques to monitor toxic chemical contamination of bottom-feeding fish, mussels and oysters, and sediments at about 300 locations throughout the United States. A related NS&T Program of directed research examines the relationships between contaminant exposure and indicators of biological responses in fish and shellfish. Through the Hazardous Materials Response and Assessment Division (HAZMAT) Scientific Support Coordination program, ORCA provides critical scientific support for planning and responding to spills of oil or hazardous materials into coastal environments. Technical guidance includes spill trajectory predictions, chemical hazard analyses, and assessments of the sensitivity of marine and estuarine environments to spills. To fulfill the responsibilities of the Secretary of Commerce as a trustee for living marine resources, HAZMAT’s Coastal Resource Coordination program provides technical support to the U.S. Environmental Protection Agency during all phases of the remedial process to protect the environment and restore natural resources at hundreds of waste sites each year.

Wozniak DVM, PhD, Texas A&M University Health Science Center, Institute for Biosciences and Technology, Program for Animal Resources, 2121 W Holcombe Blvd, Houston, TX 77030 [email protected] ABSTRACT: Each year numerous emergency response personnel including animal control officers, police officers, wildlife rehabilitators, public health officers and others either respond to calls involving venomous snakes or are forced to venture into the haunts of these animals in the scope of their regular duties. North America is home to two distinct families of native venomous snakes: Viperidae (rattlesnakes, copperheads and cottonmouths) and Elapidae (coral snakes) and southeastern Texas has indigenous species representing both groups. While some of these snakes are easily identified, some are not and many rank amongst the most feared and misunderstood animals on earth. This article specifically addresses all of the native species of venomous snakes that inhabit Health Service Region 6/5s and is intended to serve as a reference to snake identification, field safety, basic safe capture and handling methods and the currently recommended first aide measures for reptile envenomation.

The study was completed by the Universities of Maryland, Hawaii, and Florida; the National Oceanic and Atmospheric Administration (NOAA); and three tribes in Washington State (Quileute, Makah, and Quinault Nations). The study’s goal was to determine whether exposure to low levels of domoic acid over long periods of time could affect people’s health. This is the first study to evaluate long-term exposure to low levels of domoic acid from eating razor clams. After consulting with tribal leaders, tribal advisory committee members, and medical advisors, the researchers recommended tribal members from the Quileute, Makah, and Quinault Nations eat no more than 15 razor clams each month for 12 consecutive months.
