A Synopsis of the Parasites from Cyprinid Fishes of the Genus Tribolodon in Japan (1908-2013)
生物圏科学 Biosphere Sci. 52:87-115 (2013) A synopsis of the parasites from cyprinid fishes of the genus Tribolodon in Japan (1908-2013) Kazuya Nagasawa and Hirotaka Katahira Graduate School of Biosphere Science, Hiroshima University Published by The Graduate School of Biosphere Science Hiroshima University Higashi-Hiroshima 739-8528, Japan December 2013 生物圏科学 Biosphere Sci. 52:87-115 (2013) REVIEW A synopsis of the parasites from cyprinid fishes of the genus Tribolodon in Japan (1908-2013) Kazuya Nagasawa1)* and Hirotaka Katahira1,2) 1) Graduate School of Biosphere Science, Hiroshima University, 1-4-4 Kagamiyama, Higashi-Hiroshima, Hiroshima 739-8528, Japan 2) Present address: Graduate School of Environmental Science, Hokkaido University, N10 W5, Sapporo, Hokkaido 060-0810, Japan Abstract Four species of the cyprinid genus Tribolodon occur in Japan: big-scaled redfin T. hakonensis, Sakhalin redfin T. sachalinensis, Pacific redfin T. brandtii, and long-jawed redfin T. nakamuraii. Of these species, T. hakonensis is widely distributed in Japan and is important in commercial and recreational fisheries. Two species, T. hakonensis and T. brandtii, exhibit anadromy. In this paper, information on the protistan and metazoan parasites of the four species of Tribolodon in Japan is compiled based on the literature published for 106 years between 1908 and 2013, and the parasites, including 44 named species and those not identified to species level, are listed by higher taxon as follows: Ciliophora (2 named species), Myxozoa (1), Trematoda (18), Monogenea (0), Cestoda (3), Nematoda (9), Acanthocephala (2), Hirudinida (1), Mollusca (1), Branchiura (0), Copepoda (6 ), and Isopoda (1). For each taxon of parasite, the following information is given: its currently recognized scientific name, previous identification used for the parasite occurring in or on Tribolodon spp.; habitat (freshwater, brackish, or marine); site(s) of infection within or on the host; known geographical distribution in Japan; and the published source of each locality record. -

Hassan, Takanori Ishikawa, Singo SEKI and A. Mahmuda Laboratory of Aquatic Ecology, Faculty of Agriculture, Kochi University, B-200 Nankoku, Kochi 783-8502, Japan Abstract: Analyses of partial mitochondrial DNA (mtDNA) sequences support the classification of Aburahaya (Rhynchocypris lagowskii) from the Sea of Japan and Pacific Ocean. To investigate genetic population structure, we examine nucleotide sequence of the cytochrome b region. In this study we found three major geographical groups. Molecular phylogenetic analysis revealed that the population of the group 3 differentiation is 0.8759 ± 0.0333. The group 2 differentiation is 0.5333 ± 0.1801 which is collected from the Kamishyou River (Toyama Prefecture) and Hakui River (Ishikawa Prefecture) populations. The neighbor-joining tree of the mitochondrial DNA haplotypes for all specimens constructed from the Kimura’s two parameter. Among these 24 localities being clustered into 3 major geographic groups in NJ tree mtDNA segment and NJ tree mtDNA haplotype. No significant difference for the population pair wise FST was detected among these localities (P>0.05). The most parsimonious network of mtDNA haplotype of aburahaya 24 localities, estimated using the TCS algorithm. In this network showed three geographical groups. Halpotype 1-29 is one group, haplotype 30-33 is group 2 and haplotype 34-54 is group 3. Key words: Population genetic mtDNA Cyprinide Aburahaya Geographic groups Haplotype network INTRODUCTION entire range have been fragmentary. -

Washing-Up and Movement of Litter Along the Fuji Coast Captured by Live-Camera
Littoral 2010, 12009 (2011) DOI:10.1051/litt/201112009 © Owned by the authors, published by EDP Sciences, 2011 WASHING-UP AND MOVEMENT OF LITTER ALONG THE FUJI COAST CAPTURED BY LIVE-CAMERA Masahiro Ito, Department of Environmental Science and Technology, Meijo University [email protected] Abstract The total amount of litter washed up along the Japanese coast approaches nearly 25,000 tons (150,000m3). In this study, we discuss the process and timing of the deposition of litter from the sea surface onto a beach by large waves using images from live cameras located along the Fuji coast. Live camera images recorded over a period of 14 months from September 2007 to November 2008 were used in this study in addition to records of wave height, wave period, wind direction, wind velocity, and tide level. Analysis of these images and relevant oceanographic data showed that: (1) the floating litter on the sea surface in the nearshore area was washed up on the sandy beach by long waves caused by typhoons, (2) on the specified day the wind drifted the litter floating on the sea towards the shore, (3) the tidal change did not contribute to deposition of litter on the beach and (4) the clean up of litter was carried out by the appropriate section of the prefecture and city, and required a period in 1 to 5 months per event. Key words: Drifting litter, live camera, washing-up of floating litter, Fuji coast. 1. Introduction Along a beautiful 20 km stretch of the Fuji coast in Japan (Fig.1), between the Fiji and Kano river mouths, large amounts of litter are washed up on occasion by swells generated by the passage of typhoons or low pressure systems. -
