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.

  • Marine Fishes of the Azores: an Annotated Checklist and Bibliography
    MARINE FISHES OF THE AZORES: AN ANNOTATED CHECKLIST AND BIBLIOGRAPHY. RICARDO SERRÃO SANTOS, FILIPE MORA PORTEIRO & JOÃO PEDRO BARREIROS SANTOS, RICARDO SERRÃO, FILIPE MORA PORTEIRO & JOÃO PEDRO BARREIROS 1997. Marine fishes of the Azores: An annotated checklist and bibliography. Arquipélago. Life and Marine Sciences Supplement 1: xxiii + 242pp. Ponta Delgada. ISSN 0873-4704. ISBN 972-9340-92-7. A list of the marine fishes of the Azores is presented. The list is based on a review of the literature combined with an examination of selected specimens available from collections of Azorean fishes deposited in museums, including the collection of fish at the Department of Oceanography and Fisheries of the University of the Azores (Horta). Personal information collected over several years is also incorporated. The geographic area considered is the Economic Exclusive Zone of the Azores. The list is organised in Classes, Orders and Families according to Nelson (1994). The scientific names are, for the most part, those used in Fishes of the North-eastern Atlantic and the Mediterranean (FNAM) (Whitehead et al. 1989), and they are organised in alphabetical order within the families. Clofnam numbers (see Hureau & Monod 1979) are included for reference. Information is given if the species is not cited for the Azores in FNAM. Whenever available, vernacular names are presented, both in Portuguese (Azorean names) and in English. Synonyms, misspellings and misidentifications found in the literature in reference to the occurrence of species in the Azores are also quoted. The 460 species listed, belong to 142 families; 12 species are cited for the first time for the Azores.

  • New Records of Aldrovandia Oleosa (Notacanthiformes: Halosauridae) from the Eastern North Pacific Ocean
    216 CALIFORNIA FISH AND GAME California Fish and Game 96(3): 216-220; 2010 NEW RECORDS OF ALDROVANDIA OLEOSA (NOTACANTHIFORMES: HALOSAURIDAE) FROM THE EASTERN NORTH PACIFIC OCEAN DANIEL J. KAMIKAWA National Marine Fisheries Service Northwest Fisheries Science Center, Fisheries Resource Analysis and Monitoring Division 2032 SE Oregon State University Drive Newport, Oregon 97365 [email protected] DUANE E. STEVENSON National Marine Fisheries Service Alaska Fisheries Science Center, Resource Assessment and Conservation Engineering Division 7600 Sand Point Way NE Seattle, Washington 98115 The teleost family Halosauridae includes seventeen species in three genera distributed throughout the oceans of the world. The elongate body is covered with large scales and ends in a strongly tapered tail. The small dorsal fin originates close to the pointed head, which is largely scaleless; the slender pectoral fins and the anal fin are long; and, the mouth is large with the upper jaw extending beyond the lower jaw. The genus Aldrovandia currently includes at least five species, and is diagnosed within the family by the lack of scales on the vertex of the head, the lack of a distinct row of lateral-line scales, and by the heavily pigmented pyloric caeca aligned in a single row (McDowell 1973, Sulak 1977). Species of Aldrovandia are diagnosed by the coloration of the anal opening, morphometrics, meristics, and by the size and relative position of the palatine and pterygoid tooth patches. Members of this genus tend to be widespread, and at least three species (A. oleosa, A. affinis, and A. phalacra) are known from both the Atlantic and Pacific basins.

SMITH I SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 566 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Folklife Studies Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs'submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review.

  • Elopomorph Larvae Are Important Contributors to Fish Biodiversity in a Low-Latitude Oceanic Ecosystem

Moore1,2*, Dante B. Fenolio3, April B. Cook4 and Tracey T. Sutton4 1 Harriet L. Wilkes Honors College, Florida Atlantic University, Jupiter, FL, United States, 2 Harbor Branch Oceanographic Institute, Florida Atlantic University, Fort Pierce, FL, United States, 3 Center for Conservation and Research, San Antonio Zoo, San Antonio, TX, United States, 4 Halmos College of Natural Sciences and Oceanography, Nova Southeastern University, Dania Beach, FL, United States Leptocephalus larvae of elopomorph fishes are a cryptic component of fish diversity in nearshore and oceanic habitats. However, identifying those leptocephali can be important in illuminating species richness in a region. Since the Deepwater Horizon oil spill in 2010, sampling of offshore fishes in the epi-, meso-, and upper bathypelagic Edited by: depth strata of the northern Gulf of Mexico resulted in 8989 identifiable specimens of Michael Vecchione, leptocephalus larvae or transforming juveniles, in 118 taxa representing 83 recognized National Oceanic and Atmospheric Administration (NOAA), United States and established species and an additional 35 distinctive leptocephalus morphotypes Reviewed by: not yet linked to a known described species. Leptocephali account for ∼13% of the Mackenzie E. Gerringer, total species richness of fishes collected in the offshore region. A new morphotype SUNY Geneseo, United States Dave Johnson, of Muraenidae leptocephalus is also described. We compare this study with other National Museum of Natural History leptocephalus diversity studies in the western Atlantic.
