The results demonstrate the ability of O. keta to discriminate artificial stream waters containing natural levels of DFAA. © 2016 The Fisheries Society of the British Isles Key words: artificial stream waters; dissolved free amino acids; homing behaviour; PIT tag; Y-maze. INTRODUCTION The ability of Pacific salmonids to successfully return to their natal stream follow- ing outmigration to and rearing in the ocean is a critical component of the success of the group (Groot & Margolis, 1991; Dittman et al., 1996). -

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. -

A Checklist and Bibliography of Parasites of Salmonids of Japan
;r c j . 3 $JJ#~,Sci. Rep. Hokkaido Salmon Hatchery, (41) : 1-75 (1987) A Checklist and Bibliography of Parasites of Salmonids of Japan Kazuya NAGASAWA*',Shigehiko URAWA", and Teruhiko AWAKURA*~ Abstract Information on the parasites of salmonids in Japanese waters that was published during the years 1889-1986 is assembled in the form of Parasite-Host and Host- Parasite lists with accompanying bibliography. Ninety-four named species of parasites (18 Protozoa, 5 Monogenea, 21 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 are also included. The Parasite-Host list, arranged on a taxonomic basis, includes for each parasite species its currently recognized scientific name, and synonyms oc- curring in the literature, habitat (freshwater or marine), location of infection (site) within the host, species of host(s), known geographical distribution in Japanese waters, and the published source for each host and locality record. Where neces- sary, remarks and footnotes dealing with such topics as taxonomy, nomenclature, and misidentifications are included. The Host-Parasite list summarizes the species of 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 (Awa- kura, 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.

Since the end of 19th century it has been introduced in all other continents. For the present survey most of the known self-sustaining brown trout river populations in Japan have been sampled and analyzed through sequences of the entire mitochondrial DNA control region and twelve microsatellites. In Japan, brown trout are genetically not homogeneous, probably as a consequence of several introductions, one in the Azusa river and at least one other in the remaining territory. The Chuzenji hatchery houses a genetically very distinct strain, probably due to intense manipulation in isolated scientific experimentations over 30 years. Finally, most populations showed high genetic diversity (Mamachi, Kane and Odori streams, Lake Chuzenji) with the exception of the Azusa river samples. -
5. Revival of Salmon Resources and Restoration of a Traditional Ritual Of
5 Revival of Salmon Resources and Restoration of a Traditional Ritual of the Ainu, the Indigenous People of Japan Yōsuke Kosaka How Ainu people have traditionally regarded salmon Among the Ainu gods’ tales compiled and translated into Japanese by the young Ainu woman, Yukie Chiri, two stories out of 13 were on the theme of salmon. Yukie died at the age of 19 in 1922; however, her work has been well-known in Japan through her beautiful poetic translations, such as the following: ‘Silver droplets falling, falling all around, golden droplets falling, falling all around’ (Chiri 1978: 11). One of the tales about salmon begins with a scene in which, ‘A vicious man changed a clear stream into poisonous water by setting up walnut tree trunks in the river’ (Chiri 1978: 135). As a result, the salmon could not come back to the headwaters. Having discovered such a malicious act, a son of Okikirmuy, a personal god of the Ainu, fights against the spiteful man and finally defeats him in order to recover the clean water and salmon. This tale, I think, reminds us how important it is to protect the river environment for the salmon. 69 INDIGENOUS EFFLORESCENCE The Ainu people regarded famine as being caused by the misconduct of humans. An Ainu oral tradition tells of the God Who Controls Hunting Lands being informed that a human village was suffering from famine. When the god inquired the reason from another god whose spirit possesses the salmon, and from yet another god whose spirit possesses the deer, the God of Salmon answered that humans had forgotten to use a particular wooden stick when killing the salmon, which allows their souls to return to the gods’ world. -

BAYLY, DEPUTY MINISTER Part A - Introduction The decline of various premium fish stocks in the Great Lakes has created a lively interest in exotic fishes a~)ng various fishery agencies. The deteriorative environmental changes associ- ated with advancing eutrophication (Beeton, 1965) and the invasion or introductions of many new and often undesirable species, appear to be essentially irreversible changes from the fishery management point uf view. Attempting to maintain or restore natural faunal balance is, therefore, no longer an important consideration. It now seems realistic to seek new species with characteristics making them better suited to the new environmental circumstances than the historical species (Christie, 1968). This search led the Ontario Department of Lands & Forests in 1966 to mount surveys of the fishes of eastern Europe (Martin, 1967), and Japan. -
