By means of a shiphorne echo-sounder of 38 kHz, many interesting fish traces were recorded, when the vessel was crossing just above boiling fish shoals at a speed of 9 knots. At that time, the fish was observed from deck to be skipjacks of about 80 m in total length. Some acoustic and statistic considerations were taken on 23 clear echo traces from individual skipjacks among the above mentioned, i.e., 6 inverse V shape traces from stationary fish and 17 oblique and dotted traces from fish diving to deeper. The results were: i) on the stationary fish traces, a detectable angular range of the echosounder was determined as 6.5° in maximum for a skipjack of 80 cm long at a depth of 0-230 m of water and ii) from 17 fish traces shown active diving, their swimming speeds were estimated as 1.9 or 4.5 m/sec mean in 40-85 m layer of water.","subitem_description_type":"Abstract"},{"subitem_description":"本考察の結果,鶴洋丸の魚探EK-38Sでは,全長80cmのカツオを最大6.5°の角範囲で探知できることが判った.また,カツオの魚群は本船が接近したとき深層に急速移動したが,このときのカツオの平均遊泳速力は1.9,または4.5m/secであり,その鉛直成分は1.4m/sec,水平成分は4.3m/secと試算された.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学水産学部研究報告, v.55, pp.19-24; 1984","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"39400","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nishida, Hideaki"}]},{"nameIdentifiers":[{"nameIdentifier":"39401","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Takayama, Hisaaki"}]},{"nameIdentifiers":[{"nameIdentifier":"39402","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Shibata, Keishi"}]}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学水産学部"}]},"item_3_relation_29":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"40002770813","subitem_relation_type_select":"NAID"}}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00178473","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05471427","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"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":"西田, 英明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"高山, 久明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"柴田, 恵司"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-22"}],"displaytype":"detail","filename":"suisan55_019.pdf","filesize":[{"value":"2.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"suisan55_019.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/9751/files/suisan55_019.pdf"},"version_id":"a8921735-3bd3-4c3d-8235-6846ca37f85d"}]},"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":"魚探記録の解析-9 :　西太平洋赤道域で観察したカツオの遊泳速力","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"魚探記録の解析-9 :　西太平洋赤道域で観察したカツオの遊泳速力"}]},"item_type_id":"3","owner":"2","path":["727"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-01-28"},"publish_date":"2013-01-28","publish_status":"0","recid":"9751","relation_version_is_last":true,"title":["魚探記録の解析-9 :　西太平洋赤道域で観察したカツオの遊泳速力"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T01:38:35.005002+00:00"}
