1. Staff and Profile
 Professor Kazuya Nagasawa, Ph.D.
  
E-mail : ornatus(at)hiroshima-u.ac.jp

   Kazuya Nagasawa is a fish parasitologist and fisheries biologist.

   His academic background in Fisheries Science includes a PhD degree (fish parasitology, 1981) and a Master's degree (fish parasitology, 1978) from the University of Tokyo. He earned his Bacheror of Fisheries Science (aquaculture, 1975) at the Tokyo University of Fisheries (currently Tokyo University of Marine Science and Technology).
   Dr. Nagasawa joined Hiroshima University in September 2005. He formerly worked at the Hokkaido Prefectural Fisheries Experimental Station (1981-1991), National Research Institute for Far Seas Fisheries (1991-2001), National Research Institute for Aquaculture (2001-2003) and National Tohoku Fisheries Research Institute (April to August in 2005). For two years from March 2003 to March 2005, he served as Special Adviser at the Aquaculture Department of the Southeast Asian Fisheries Development Center (SEAFDEC-AQD) in the Philippines for an international project on fish diseases in Southeast Asia.
   
   As of October 2011, Professor Nagasawa authored and co-authored 27 books (six as an editor, two as a single author, 19 as a chapter contributor) related to fish parasites and also fisheries biology in both Japanese and English publications. He also has over 210 original papers (of which, 167 papers were published in peer-reviewed journals), 53 review articles (22 in peer-reviewed journals) and 97 scientific essays.
   
   Dr. Nagasawa has served in the editorial board for Journal of Marine Biological Association of the United Kingdom (1992-present). Likewise, he served as Editor-in-Chief for International Ichthyoparasitological Newsletter (1992-1996) and as an editorial member for Folia Parasitologica (1992-1996), Fish Pathology (1993-2004), Bulletin of Japanese Society of Fisheries Oceanography (1999-2002), and Fisheries Science (2005-2008).
   
   In addition to parasitology, Dr. Nagasawa worked on fish ecology and fisheries oceanography. He received the R.E. Foerster Award in Canada in 1998 with his work with a Canadian scientist on the impact of global warming on the production of Pacific salmon. He was also awarded in 2001 by the Japanese Association of Fisheries Journalists with his work on the ocean ecology of Pacific salmon.
   
   Dr. Nagasawa's expertise on fish parasites and others has led to several invitations as a lecturer at the Ocean Research Institute of Kiel University, Kiel, Germany (1989); the School of Marine Science, Tokai University, Shizuoka, Japan (1992-1996); the Faculty of Science, Nara Women's University, Nara, Japan (1995); and the Faculty of Science, Hokkaido University, Sapporo, Japan (2009).

   He also stayed as a visiting scientist at the Natural History Museum, London, U.K.; Institute of Parasitology, Academy of Sciences of the Czech Republic, Ceske Budejovice, Czech Republic; Institute of Biological Sciences, University of Malaya, Kuala Lumpul, Malaysia; Institute of Fisheries and Oceanography, Kamchatka, Russia; Pacific Biological Station, Nanaimo, B.C., Canada; and Fisheries Research Institute, University of Washington, Seattle, U.S.A.

2. Postdoctoral Fellows and Their Research - 2 persons

1. Dr. Ione Madinabeitia
    
   
Ione Madinabeitia finished her PhD work in March 2011 at Hiroshima University. Her PhD dissertation is "Taxonomical and ecological studies on the metazoan parasites of sparid fishes from Japan and other countries." Her PhD mentor was Professor Kazuya Nagasawa.

    Ione is a Spanish. After she finished her undergraduate program at the California State University, Long Beach (CSULB), in California, U.S.A., she came to Japan as a Master's student. At CSULB, she was a student of Professor Ju-shey Ho (left in the right picture below), a prominent scientist for research on the symbiotic copepods of aquatic animals.

    Ione is a postdoctoral fellow supported by the Japan Society for the Promotion of Science. She has started publishing papers on the basis of her PhD dissertation. Her current publications are listed below:

2. Dr. Yuzo Ota
    
   Yuzo Ota joined the Nagasawa Research Group for Aquaparasitology in April 2011. He obtained a PhD degree at the University of Ryukyus in Okinawa, Japan, in 2010. He wrote his PhD dissetation entitled "Taxonomical studies on gnathiids (Crustacea, Isopoda, Gnathiidae) from Okinawa Islands, Japan." The animals Yuzo has studied are gnathiid isopods. He has published some papers (listed below) on the taxonomy and ecology of these isopods collected in Okinawan waters. One of the papers (Ota et al., 2008) was awarded by the Japanese Society of Crustacean Research in 2009.

   Yuzo is a postdoctoral fellow supported by the Japan Society for the Promotion of Science. He is also interested in subtropical insects and has some papers, too.

4. The Species Studied

   Various aspects of the biology of fish parasites, including the taxonomy, ecology and pathogenicity, are studied. The fishes examined are mostly marine fishes from the Seto Inland Sea. Our current interest is also the fauna of parasites, such as copepods, monogeneans and leeches, found on subtropical marine and freshwater fishes in Okinawa, southernmost prefecture in Japan.

   The impact of the parasites introduced with aquatic animals from other countries on freshwater ecosystems in Japan has also been studied. The fishes studied are bluegill (Lepomis macrochirus) and largemouth bass (Micropterus salmoides). These fishes have been widely established in this country. The fauna and distribution of their parasites are being investigated.

    In addition to these species, Japanese eels (Anguilla japonica) and river-resident amago salmon (Oncorhynchus masou ishikawae) are studied for their stock enhancement. Research on the sexual selection of loggerhead turtles (Caretta caretta) held at an aquarium is also conducted.
