SEATTLE, WA March 1972 NOAA TECHNICAL REPORTS National Marine Fisheries Service, Special Scientific Report-Fisheries Series The major responsibilities of the National Marine Fisheries Service (NMFS) are to monitor and assess the abundance and geographic distribution of fishery resources, to understand and predict fluctuations in the quantity and distribution of these resources, and to establish levels for optimum use of the resources. NMFS is also charged with the development and implementation of policies for managing national fishing grounds, develop- ment and enforcement of domestic fisheries regulations, surveillance of foreign fishing off United States coastal waters, and the development and enforcement of international fishery agreements and policies. NMFS also as- sists the fishing industry through marketing service and economic analysis programs, and mortgage insurance and vessel construction subsidies. It collects, analyzes, and publishes statistics on various phases of the industry. The Special Scientific Report—Fisheries series was established in 1949. The series carries reports on scien- tific investigations that document long-term continuing programs of NMFS, or intensive scientific reports on studies of restricted scope. The reports may deal with applied fishery problems. The series is also used as a medium for the publication of bibliographies of a specialized scientific nature. NOAA Technical Reports NMFS SSRF are available free in limited numbers to governmental agencies, both Federal and State. They are also available in exchange for other scientific and technical publications in the marine sciences.

DAILEY Department of Biology California State College at Long Beach Long Beach, California 90801 ABSTRACT Parasite-host and host-parasite lists, with supporting references, of the ecto- and endoparasites recorded from marine mammals of the North American west coast are provided. Excluding records in which the parasites have not been identified to the spe- cies level, there are known 15 trematodes, 3 cestodes, 10 nematodes, 7 acanthocephalans, 1 copepod, and 10 amphipods from 22 species of Cetacea; 8 trematodes, 10 cestodes, 12 nematodes, 8 acanthocephalans, 5 anoplurans, and 5 acarines from 8 species of Pinni- pedia; and 4 trematodes, 2 cestodes, 1 nematode, 3 acanthocephalans, and 1 acarine from a single species of Carnivora. Previously unpublished records which are included here are: Anisakis simplex from Phocoenoides dalli and Orcinus orca, British Columbia; Cyamus balaenopterae from Balaenoptera musculus, California; Cyamus erraticus from Balaena glacialis, Alaska; Cyamus scammoni from Eschrichtius gibbosus, Alaska; Antarctophthirus trichechi from Odobenus rosmarus, Alaska.

  • Effects of Parasites on Marine Maniacs

    Effects of Parasites on Marine Maniacs

    EFFECTS OF PARASITES ON MARINE MANIACS JOSEPH R. GERACI and DAVID J. ST.AUBIN Department of Pathology Ontario Veterinary College University of Guefph Guelph, Ontario Canada INTRODUCTION Parasites of marine mammals have been the focus of numerous reports dealing with taxonomy, distribution and ecology (Defyamure, 1955). Descriptions of associated tissue damage are also available, with attempts to link severity of disease with morbidity and mortality of individuals and populations. This paper is not intended to duplicate that Iiterature. Instead we focus on those organisms which we perceive to be pathogenic, while tempering some of the more exaggerated int~~retations. We deal with life cycles by emphasizing unusual adap~t~ons of selected organisms, and have neces- sarily limited our selection of the literature to highlight that theme. For this discussion we address the parasites of cetaceans---baleen whales (mysticetes), and toothed whales, dolphins and porpoises (odon- tocetes): pinnipeds-true seals (phocidsf, fur seals and sea Iions (otariidsf and walruses (adobenids); sirenians~anatees and dugongs, and the djminutive sea otter. ECTOPARASITES We use the term “ectoparasite’” loosely, when referring to organisms ranging from algae to fish which somehow cling to the surface of a marine mammal, and whose mode of attachment, feeding behavior, and relationship with the host or transport animal are sufficiently obscure that the term parasite cannot be excluded. What is clear is that these organisms damage the integument in some way. For example: a whale entering the coid waters of the Antarctic can acquire a yelIow film over its body. Blue whales so discoiored are known as “sulfur bottoms”.

    1 Amphipoda of the Northeast Pacific

    Amphipoda of the Northeast Pacific (Equator to Aleutians, intertidal to abyss): VII. Caprelloidea – a review Donald B. Cadien, LACSD 22July04 (revised 20Apr15) Preface The purpose of this review is to bring together information on all of the species reported to occur in the NEP fauna. It is not a straight path to the identification of your unknown animal. It is a resource guide to assist you in making the required identification in full knowledge of what the possibilities are. Never forget that there are other, as yet unreported species from the coverage area; some described, some new to science. The natural world is wonderfully diverse, and we have just scratched its surface. Anthropogenic transport is also constantly introducing exotic species into our area, particularly in this superfamily. Introduction to the Caprelloidea Until recent years the caprellids were viewed as a separate suborder of the order Amphipoda, equivalent to the gammarids and the hyperiids. The discovery of the caprogammarids (Kudrjashov & Vassilenko 1966) began to call this into question (McCain 1968, 1970; Laubitz 1976, J. L. Barnard & Karaman 1983), and, following the revisionary work of Myers and Lowry (2003), they are fully nested into the gammaroids based on morphologically based cladistic analysis of their phylogeny. This position was retained in the larger analysis of Lowry & Myers (2013) which established the senticaudates, to which all of the caprellidians belong. Not all workers are willing to accept the revisions of Myers and Lowry, particularly Stella Vassilenko, who feels that it is inappropriate and based on the wrong evidence (Vassilenko 2006). She feels that caprellids should retain their own separate suborder as Caprellidea, and that Cyamida and Caprellida both should retain infraordinal rank.
