INFORMATION TO USERS This reproduction was made from a copy of a document sent to us for microfilming. While the most advanced technology has been used to photograph and reproduce this document, the quality of the reproduction is heavily dependent upon the quality of the material submitted. The following explanation of techniques is provided to help clarify markings or notations which may appear on this reproduction. 1.The sign or “target” for pages apparently lacking from the document photographed is “Missing Page(s)”. If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting through an image and duplicating adjacent pages to assure complete continuity. 2. When an image on the film is obliterated with a round black mark, it is an indication of either blurred copy because of movement during exposure, duplicate copy, or copyrighted materials that should not have been filmed. For blurred pages, a good image of the page can be found in the adjacent frame. If copyrighted materials were deleted, a target note will appear listing the pages in the adjacent frame. 3. When a map, drawing or chart, etc., is part of the material being photographed, a definite method of “sectioning” the material has been followed. It is customary to begin filming at the upper left hand comer of a large sheet and to continue from left to right in equal sections with small overlaps. If necessary, sectioning is continued again—beginning below the first row and continuing on until complete. 4. For illustrations that cannot be satisfactorily reproduced by xerographic means, photographic prints can be purchased at additional cost and inserted into your xerographic copy. These prints are available upon request from the Dissertations Customer Services Department. 5. Some pages in any document may have indistinct print. In all cases the best available copy has been filmed. University Micrdnlms International 300 N. Zeeb Road Ann Arbor, Ml 48106 8312104 Shirley, Thomas C.

Shirley B.S., Texas A&I University, 1969 M. S., Texas A&I University, 1974 December 1982 ACKNOWLEDGEMENTS This project has benefitted from the efforts, advice and criticism of a great many people. Foremost among those to be thanked is Dr. William B, Stickle, my committee chairman, for his advice, encouragement and patience. I thank my committee members, Drs. J. B. Woodring, W. J. Harman, Dr. J. W. Fleeger and the late N. B. Causey, Department of Zoology and Physiology, Dr. J. W. Day, Department of Marine Sciences, all from Louisiana State University, and Dr. H. D. Hoese, Department of Biology, University of Southwestern Louisiana, for their advice and constructive reviews of the manuscript. Gary Mayeaux, David Randall, Deborah French, Nancy Henderson, Jan Judice, Cay Villars and Karen Westphal were tireless "pickers" and sample sorters. Larry Racca, Louisiana Wildlife and Fisheries Commission, was the boat captain and an endless source of wildlife wisdom. Guy J. Denoux was a collaborator in the collection of hydrographic data and displayed indefatigable patience in the washing of myriads of bottom samples. Louis Kniepper helped in the processing of trawl samples and identified most of the fish speci­ mens. Drs. D. L. Felder and M. S. Loden aided in the identification of crustaceans and oligochaetes, respectively. Jerry Hader helped in pro­ gram formulation and debugging. The project was made possible by funding from PRECOL (Petroleum Refiners Environmental Council of Louisiana). The Louisiana Wildlife and Fisheries Commission generously provided a boat and numerous forms of assistance. Lastly, it is diffi­ cult for me to express sufficient gratitude to my wife, Susan, not only for editing the manuscript, but for her support and concern for my personal goals. ii TABLE OF CONTENTS Page ACKNOWLEDGEMENTS .................................................... ii LIST OF TABLES ......................................................... iv LIST OF FIGURES...................................................... v GLOSSARY OF TERMS......................................................vii ABSTRACT............................................................... ix INTRODUCTION................................................ 1 MATERIALS AND METHODS ...................................... 3 The Study A r e a .......................................... 3 Hydrographic Data. ................................. 6 Biological Samples ..................................... 9 Sediments................................................ 9 Statistical Analyses ................................... 10 RESULTS .................................................... 14 Hydrographic Data........................................ 14 Sediments................................................ 33 Faunal Data.............................................. 38 Community Structure...................................... 43 Classification .......................................... 50 Normal Analysis (Q or Station) ......................... 50 Inverse Classification ...... .......... ..... 57 DISCUSSION.................................................. 67 LITERATURE CITED............................................ 76 APPENDICES........................................................... 85 VITA.................................................................. 133 iii LIST OF TABLES Table Page 1 Locations of sampling stations: longitudes and lattltudes, buoy numbers and distance from Calcasieu Pass................................. 7 2 Water temperature: means and ranges by station and temperature............................. 24 3 Dissolved oxygen data: means and ranges of mg ant* Percent saturation by station and position ...................... .... ............ 32 4 Rank, total number collected, frequency of occurrence and percentage of total collections for ten most abundant fish and invertebrates in trawl samples. 3? 5 Attributes of station groups............................ 56 6 Members of species groups ........................... 61 iv LIST OF FIGURES Figure Page 1 Map of the Calcasieu estuary with station locations............................................ 4 2 Means and ranges of salinity by station and position............................................ 15 3 Monthly surface salinities for stations 1, 3, 5 and 7.............................................. 17 4 Monthly bottom salinities for stations I, 3, 7 and 9 .............................................. 19 5 Means and ranges of water temperatures by sampling period................................. 22 6 Temperature-salinity polygons for surface and lake or channel bottom for stations 1, 4, 7, 9 and 10. 25 7 Means and ranges of dissolved oxygen content (mg 0^/l) by station and position................... 28 8 Means and ranges of percent oxygen saturation by station and position............................

An updated checklist and characterisation of the ichthyofauna (Elasmobranchii and Actinopterygii) of the Laguna de Tamiahua, Veracruz, Mexico. Acta Ichthyol. Piscat. 48 (4): 341–362. Background. Laguna de Tamiahua is ecologically and economically important as a nursery area that favours the recruitment of species that sustain traditional fisheries. It has been studied previously, though not throughout its whole area, and considering the variety of habitats that sustain these fisheries, as well as an increase in population growth that impacts the system. The objectives of this study were to present an updated list of fish species, data on special status, new records, commercial importance, dominance, density, ecotic position, and the spatial and temporal distribution of species in the lagoon, together with a comparison of Tamiahua with 14 other Gulf of Mexico lagoons. Materials and methods. Fish were collected in August and December 1996 with a Renfro beam net and an otter trawl from different habitats throughout the lagoon. The species were identified, classified in relation to special status, new records, commercial importance, density, dominance, ecotic position, and spatial distribution patterns.

  • 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.

    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.

  • Deep‐Sea Coral Taxa in the U.S. Gulf of Mexico: Depth and Geographical Distribution
    Deep‐Sea Coral Taxa in the U.S. Gulf of Mexico: Depth and Geographical Distribution by Peter J. Etnoyer1 and Stephen D. Cairns2 1. NOAA Center for Coastal Monitoring and Assessment, National Centers for Coastal Ocean Science, Charleston, SC 2. National Museum of Natural History, Smithsonian Institution, Washington, DC This annex to the U.S. Gulf of Mexico chapter in “The State of Deep‐Sea Coral Ecosystems of the United States” provides a list of deep‐sea coral taxa in the Phylum Cnidaria, Classes Anthozoa and Hydrozoa, known to occur in the waters of the Gulf of Mexico (Figure 1). Deep‐sea corals are defined as azooxanthellate, heterotrophic coral species occurring in waters 50 m deep or more. Details are provided on the vertical and geographic extent of each species (Table 1). This list is adapted from species lists presented in ʺBiodiversity of the Gulf of Mexicoʺ (Felder & Camp 2009), which inventoried species found throughout the entire Gulf of Mexico including areas outside U.S. waters. Taxonomic names are generally those currently accepted in the World Register of Marine Species (WoRMS), and are arranged by order, and alphabetically within order by suborder (if applicable), family, genus, and species. Data sources (references) listed are those principally used to establish geographic and depth distribution. Only those species found within the U.S. Gulf of Mexico Exclusive Economic Zone are presented here. Information from recent studies that have expanded the known range of species into the U.S. Gulf of Mexico have been included. The total number of species of deep‐sea corals documented for the U.S.
