To reduce the number of entangled porpoises, we researched the mechanism of porpoise's entanglements. We used Harbor porpoises Phocoena Phocoena in the coastal area of Hokkaido, Japan. Harbor porpoises are of the same family as Dall's porpoises. We observed the porpoise's behavior in the net enclosure in which we set the gill net, the float line, as well as the rope. The results may be summarized as follows: Harbor porpoises can recognize the gill net at daytime, if they are aware of it. At night, porpoises can also recognize the gill net, if they have already know the existence of it. Porpoises can easier recognize a line than a netting. The fin of porpoises get entangled in the gill net. When they obliquely thrust into the gill net, they get entangled in it. The food causes reduction of porpoises' cautiousness. The source level of porpoise's clicks is in the range 125 to 150dB.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産工学研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"National Research Institute of Fisheries Engineering","subitem_publisher_language":"en"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"nrife_gs_5_25","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本農学文献記事索引(agriknowledge)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010500882","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00048467","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0289-5153","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"赤松, 友成","creatorNameLang":"ja"}],"familyNames":[{"familyName":"赤松","familyNameLang":"ja"}],"givenNames":[{"givenName":"友成","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"畠山, 良己","creatorNameLang":"ja"}],"familyNames":[{"familyName":"畠山","familyNameLang":"ja"}],"givenNames":[{"givenName":"良己","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"石井, 憲","creatorNameLang":"ja"}],"familyNames":[{"familyName":"石井","familyNameLang":"ja"}],"givenNames":[{"givenName":"憲","givenNameLang":"ja"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ネズミイルカの流し網への羅網過程に関する実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ネズミイルカの流し網への羅網過程に関する実験","subitem_title_language":"ja"},{"subitem_title":"Process of Harbor Porpoise's Entanglement in the Gill Net","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716955731445"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-19"},"publish_date":"2024-06-19","publish_status":"0","recid":"2007959","relation_version_is_last":true,"title":["ネズミイルカの流し網への羅網過程に関する実験"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-03-19T02:52:13.908866+00:00"}
