They provide an unparalleled opportunity for studying marine biogeography because they include the globally distributed families Tripterygiidae (triplefin blennies) and Blenniidae (combtooth blennies), the temperate Clinidae (kelp blennies), and three largely Neotropical families (Labrisomidae, Chaenopsidae, and Dactyloscopidae). However, interpretation of these distributional patterns has been hindered by largely unresolved inter-familial relationships and the lack of evidence of monophyly of the Labrisomidae. Results: We explored the phylogenetic relationships of the Blenniiformes based on one mitochondrial (COI) and four nuclear (TMO-4C4, RAG1, Rhodopsin, and Histone H3) loci for 150 blenniiform species, and representative outgroups (Gobiesocidae, Opistognathidae and Grammatidae). According to the consensus of Bayesian Inference, Maximum Likelihood, and Maximum Parsimony analyses, the monophyly of the Blenniiformes and the Tripterygiidae, Blenniidae, Clinidae, and Dactyloscopidae is supported.

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.

    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.

    Burst of New Orleans

    CONFEDERATE HISTORICAL ASSOCIATION OF BELGIUM NavalHistorical Center) ( battleof New Orleans The I I was ordered to report to Commodore W.C. Whittle, commanding the naval station at New Orleans, for duty afloat. A powerful fleet of ships of war and bomb vessels, under the command of Commodore (afterwards Admiral) D. G. Farragut, was then assembling at the mouth of the Mississippi, for an attack upon New Orleans, in which a large land force under General Ben Butler (afterwards called the Beast) was to cooperate. The citizens were under the impression that the place was impregnable. General J. Duncan1, commanding Forts Jackson and St. Philip, below the city, was considered one of the best artillerists in the service ; and the land defense was entrusted to General M. Lovell, with a well appointed force under his command. The people of that gay city were occupied as usual in business and pleasure, and continued unconscious of their peril up to the very time when the Federal fleet passed the forts. But the condition of affairs, so far as naval defense was concerned, was lamentable. The regular C. S. naval fleet consisted of the CSS Louisiana (Captain C.F. McIntosh2) and carrying the flag of Commodore Mitchell ; the steamer McRae (Captain T.B. Huger), carrying six light 32-pounders and nine-inch pivot gun ; the steamer Jackson (Captain F.B. Renshaw), with two pivoted smooth bore 32-pounders ; the small iron plated Ram Manassas (Captain A.F. Warley), carrying one 32-pounder carronade in the bow ; and two launches, each carrying a howitzer and a crew of twenty men.

The diversity, abundance, distribution and substrate association of the regular sea urchins found at the South part of Isla Verde lagoon reef, Veracruz, Mexico is presented. Four field sampling trips where made between October, 2000 and October, 2002. One sampling quadrant (23 716 m2) the more representative, where selected in the southwest zone of the lagoon reef, but other sampling sites where choose in order to cover the south part of the reef lagoon. The species found were: Eucidaris tribuloides tribuloides, Diadema antillarum, Centrostephanus longispinus rubicingulus, Echinometra lucunter lucunter, Echinometra viridis, Lytechinus variegatus and Tripneustes ventricosus. The relation analysis between the density of the echi- noids species found in the study area and the type of substrate was made using the Canonical Correspondence Analysis (CCA). The substrates types considerate in the analysis where: coral-rocks, rocks, rocks-sand, and sand and Thalassia testudinum.

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences.

    South Carolina Department of Natural Resources

    FOREWORD Abundant fish and wildlife, unbroken coastal vistas, miles of scenic rivers, swamps and mountains open to exploration, and well-tended forests and fields…these resources enhance the quality of life that makes South Carolina a place people want to call home. We know our state’s natural resources are a primary reason that individuals and businesses choose to locate here. They are drawn to the high quality natural resources that South Carolinians love and appreciate. The quality of our state’s natural resources is no accident. It is the result of hard work and sound stewardship on the part of many citizens and agencies. The 20th century brought many changes to South Carolina; some of these changes had devastating results to the land. However, people rose to the challenge of restoring our resources. Over the past several decades, deer, wood duck and wild turkey populations have been restored, striped bass populations have recovered, the bald eagle has returned and more than half a million acres of wildlife habitat has been conserved. We in South Carolina are particularly proud of our accomplishments as we prepare to celebrate, in 2006, the 100th anniversary of game and fish law enforcement and management by the state of South Carolina. Since its inception, the South Carolina Department of Natural Resources (SCDNR) has undergone several reorganizations and name changes; however, more has changed in this state than the department’s name. According to the US Census Bureau, the South Carolina’s population has almost doubled since 1950 and the majority of our citizens now live in urban areas.
