A Checklist and Bibliography of Parasitesof Salmonids of Japan

Kazuya NAGASAWA*',Shigehiko URAWA",and Teruhiko AWAKURA*~

Abstract
Information on the parasites of salmonids in Japanese waters that was publishedduring the years 1889-1986 is assembled in the form of Parasite-Host and HostParasite lists with accompanying bibliography. Ninety-four named species ofparasites (18 Protozoa, 5 Monogenea, 2 1 Trematoda, 7 Cestoidea, 19 Nematoda, 15
Acanthocephala, 1 Hirudinoidea, 1 Mollusca, 1 Branchiura, 5 Copepoda, 1 Isopoda)
have been reported, and numerous other parasites not identified to species level arealso included. The Parasite-Host list, arranged on a taxonomic basis, includes foreach parasite species its currently recognized scientific name, and synonyms occurring in the literature, habitat (freshwater or marine), location of infection (site)
within the host, species of host(s), known geographical distribution in Japanesewaters, and the published source for each host and locality record. Where necessary, remarks and footnotes dealing with such topics as taxonomy, nomenclature,and misidentifications are included. The Host-Parasite list summarizes the speciesof parasites from each species of salmonid and their geographical distributions.
Although taxonomic revision is not the aim of the checklist, the following three new
combinations and one new synonym are proposed : Microsporidium takedai (Awakura, 1974) n. comb. for Nosemu tukedui ; Sterliudochonu ephemeridurum (Linstow,1872) n. comb. for Cystidicoloides ephemeridurum ; and Salvelinema ishii (Fujita,1941) new synonym of S. salvelini (Fujita, 1939) n. comb. for Metabronemu salvelini.

Introduction
In 1889, the first paper on parasites of Japanese salmonids was published by Prof. I. Ijima
of Tokyo Imperial University. Since then, a number of papers dealing with parasites of
salmonids in Japanese waters have been published. In 1958 and 1961, Prof. T. Fukui of
Yokohama Municipal University compiled excellent reviews of parasites of Japanese salmonids. However, during the last two decades, our knowledge on this subject has increased
considerably. Thus, it seems necessary and timely to make a new checklist and bibliography.
Additionally, since many papers on salmonid parasites in Japanese waters have been written in
Japanese, a checklist compiled in English will be useful to introduce our knowledge to foreign
investigators.
This checklist involves records during the period 1889-1986 from published scientific
literature and annual reports of national and prefectural government institutions. Where
necessary, records contained in publications that do not provide original host or locality data
and those from abstracts and proceedings of scientific meetings are also included. However,recent records of parasites of masu salmon from the Annual Reports of the Hokkaido Fish
Hatchery are excluded, because based on the same material Dr. T. Awakura and his colleagues(1981-) have been publishing serial papers, records from which are included.
This checklist consists of seven sections : Introduction, Parasite-Host List, Host-Parasite
List, Acknowledgmknts, References, Supplementary References, and Index. This compositionis the same as given by Margolis and Arthur (1979).
In the PARASITE-HOST LIST, parasites are arranged by their phyla and classes in thefollowing order : Sarcomastigophora (Zoomastigophorea), Apicomplexa (Sporozoea), Microspora (Microsporea), Ascetospora (Stellatosporea), Myxozoa (Myxosporea), Ciliophora(Kinetofragminophorea, Oligohymenophorea), Platyhelminthes (Monogenea, Trematoda,
Cestoidea), Nemathelminthes (Nematoda, Nematomorpha), Acanthocephala, Annelida(Hirudinoidea), Mollusca, and Arthropoda (Crustacea : Branchiura, Copepoda, Isopoda). The
basis of the system of higher classification used herein for the “Metazoa” follows that given by
Margolis and Arthur (1979), whereas classification of the “Protozoa” follows that newly
proposed by Levine et al. (1980). Families, genera, and species are listed alphabetically. For
each species of parasite contained herein, the following information is provided :1) The current scientific name, including author(s) and date(s), followed by any recognizedsynonyms that have been used in establishing records from Japanese salmonid(s). No attempt
has been made to evaluate systematically the validity of the published reports. However,attention is drawn to obvious errors and tentative or uncertain identifications, and a few newname emendations are proposed where considered absolutely necessary. In addition, Harada’s

2

Checklist of Parasites of Japanese Salmonids(1935) view that the three species of Acanthocephalus, A. oncorhynchi, A. aculeatus and A,
acerbus, are synomymous with A. echigoensis is not accepted herein because his proposal seems
to require reassessment based on abundant material.
2) The habitat in which the parasite was acquired and normally completes its life cycle isgiven as FW for fresh water, and M for marine.
3) The site($ or location(s) of infection of the parasite in or on its host(s). In cases where
the site was not given in the original report, the typical site of occurrence was determined fromother records and is enclosed in square brackets. Furthermore, attention is drawn to aberrantsites of infection.
4) The host(s). Records are listed by host based on the scientific names used in the ‘‘Listof Japanese Fishes” that appeared in the ‘‘Dictionary of Japanese Fish Names and Their
Foreign Equivalents” edited by the Ichthyological Society of Japan (1981). In cases where only
common names were given in original reports, assignment of species was based on the common
name used or on collection locality. The specific names of Japanese charrs of the genus
Salvelinus requires a special comment. Fujita (1928), Yamaguti (1935, 1941, 1954), and Fukui
and Morisita (1937, 1938) used “Sulvelinus malma” for charrs collected in Honshu, the mainisland of Japan. However, since in Japan this fish is restricted to Hokkaido, Salvelinus pluvius
is used based on collection locality. Fujita (1940) also used “Salvelinus malma” for charrs fromthe Chitose River, Hokkaido, but as pointed out by Moravec et al.(1985) these charrs areapparently Salvelinus leucomaenis. In addition, although Seki (1975b) used “Salvelinus malma”
for charrs caught in Lake Shikaribetsu, Salvelinus malma miyabei, which was given as “S.
miyabei” in the “List of Japanese Fishes”, is used because this local form is apparently a variantof S. malma and endemic in the lake. Numbers in parentheses after each host name correspond with the numbers assigned to the references establishing the particular parasite-hostrecords.
5) The distribution (Dist.) of the parasite is indicated by Prefectural boundaries (Fig. 1) in
geographical order from northeast to southwest. The records from the southern Kurile Islands
such as Etorofu Island and Shikotan Island are also included. In cases of marine species, thename of the prefecture nearest the collection site is given.
6) The record(s). The authors responsible for the records are listed in chronological order.
Reference numbers correspond to those given after the appropriate host species. Each reference is followed by the locality or localities consisting of two parts, prefecture(s) and detailed
collection locality or localities from which the parasite was reported. For references in which
locality record was not given, the geographical locality is shown by a dash (-). When only one
host species is listed for a particular parasite the references are not numbered, and when all
records are from the same prefecture only detailed collection localities were listed after theauthors’ names.
7) Remarks. Under Remarks, comments are given on systematics, nomenclature, and thereassignment of misidentified material.
8) Footnotes. Under Footnotes are included notes on specific topics such as tentative
identifications, aberrant sites of infection, and the misspelling of the parasite’s scientific names

Nagasawa, Urawa, and Awakura

and of collection localities.
In the HOST-PARASITE LIST, genera and species of hosts are listed alphabetically.
Each host’s scientific name including author(s) is followed by the English common name and theJapanese common name(s). Host synonyms included are only those associated with Japaneseparasite records. After the name of each species of parasite, its geographic distribution for thehost in question is given in parentheses. A single asterisk (*) after the parasite name indicatesa tentative or ambiguous parasite identification, and a double asterisk (**) after the parasitename shows that the occurrence of the parasite in the host in question has been considered asabnormal. An interrogation mark (?) preceding a parasite name indicates questionable validity of the parasite identification and the same mark after a locality citation indicates anambiguous or uncertain locality record.
The REFERENCES include those directly referred to in the parasite-host list, and the
SUPPLEMENTARY REFERENCES involve publications dealing with various aspects ofparasites of Japanese salmonids but which do not contain original parasite-host records. In
both reference lists, authors are listed in alphabetical and chronological orders. In cases where
only a Japanese title was given by the original author(s), the equivalent English title is provided
in square brackets.
An INDEX to parasite and host scientific names is given to facilitate access to informationin the parasite-host and host-parasite lists.

Remarks : Awakura (1983a, 1984a) treated
Myxobolus sp. A described by Awakura
et al. (1982a, 1984b) as Myxobolus sp.
Based on Pugachev and Khokhlov (1979),
this species is identifiable as Myxobolus
neurobius by its shape and size of spore.
An oviform myxosporean reported by
Murakami (1979a, b, c, 1980a, b, 1982a, b,
c, e, 1983, 1984) seems to be identical with
M . neurobius. Because the parasite
identification remains confused, there isa need for detailed comparative studies
based on the materials from a number ofhost species and localities.
