Morphological characteristics of the markless and red-spotted masu trouts were examined. These masu trouts,heretofore, have been regarded as different species, Oncorhynchus iwame KIMURA et NAKAMURA and O.rhodurus (Salmo(O.)masou macrostomus in this paper). The two masu trouts differ in numbers of pectoral fin ray,ventral fin ray,gill raker and pyloric coeca. However, such differences are not so remarkable for taxonomic character as they are attributed to different species. Moreover, since significant differences are not between the two masu trouts in other meristic and measurable characteristics and there is no evidence of ecological isolation as far as our observations, those differences are intraspecific variations rather than are reflected specific criteria. Consequently, these are no remarked differences between the two fishes except for the color patterns of parr marks and red spots,and then it is insufficient that they are considered separate biological species by only aspects of colouration.Therefore,the markless masu trout is considered a variation form (a kind of albinism?) from the red-spotted masu trout. In addition,similar form pairs exist in some steams in Kyushu,Shikoku and Honshu Islands but, at present, the morphological and genetical relationships between the form pairs in these regions are almost unknown, and zoogeographical problem also remains to be proved.","subitem_description_type":"Abstract"}]},"item_4_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学水産学部"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0287-5772","subitem_source_identifier_type":"PISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN0023428X","subitem_source_identifier_type":"NCID"}]},"item_4_subject_16":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"487","subitem_subject_scheme":"NDC"}]},"item_4_text_18":{"attribute_name":"その他のタイトル","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Morphological comparisons between the markless masu trout (Iwame) and the red-spotted masu trout (Amago), Salmo (Oncorhynchus) masou macrostomus GÜNTHER, in the Mikuni-dani stream of Mie Prefecture, Japan"}]},"item_4_text_63":{"attribute_name":"ノート","attribute_value_mlt":[{"subitem_text_value":"Agropedia提供データ"}]},"item_4_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Departmental Bulletin Paper / 紀要論文"}]},"item_4_version_type_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"森, 誠一","creatorNameLang":"ja"},{"creatorName":"Mori, Seiichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"名越, 誠","creatorNameLang":"ja"},{"creatorName":"Nagoshi, Makoto","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-18"}],"displaytype":"detail","filename":"AN0023428X0001305.pdf","filesize":[{"value":"391.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN0023428X0001305.pdf","url":"https://mie-u.repo.nii.ac.jp/record/5636/files/AN0023428X0001305.pdf"},"version_id":"1f0181ed-343a-47a6-a301-1404005cc8c1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Morphology","subitem_subject_scheme":"Other"},{"subitem_subject":"Salmo(iwame and amago)","subitem_subject_scheme":"Other"},{"subitem_subject":"Intraspecific variation","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"三重県三国谷のイワメとアマゴにおける形態比較","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"三重県三国谷のイワメとアマゴにおける形態比較","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"13","path":["432"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-06-21"},"publish_date":"2007-06-21","publish_status":"0","recid":"5636","relation_version_is_last":true,"title":["三重県三国谷のイワメとアマゴにおける形態比較"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2023-10-11T07:11:59.989557+00:00"}
