Okinawa Island between December and April. Around the same period of time, dead strandings and \u201cbycatch\u201d of humpback whales that are caught accidentally in fixed nets placed in coastal waters are also occasionally observed around Okinawa Island. In this paper, we report on humpback whale strandings and bycatches confirmed around Okinawa Island between 1996 and 2018. A total of 12 cases consisting of 7 strandings and 5 bycatches (in a fixed net placed in the coastal waters of Yomitan-son) were recorded during the approximately 22-year study period. All the strandings and bycatches took place between early January and early April, and their occurrence increased in the peak season for the arrival of humpback whales into Okinawan waters between the middle and the end of February. Only three dead strandings of humpback whales were recorded between 1996 and 2014, whereas one dead stranding each has been observed for 4 consecutive years since 2015; the frequency of the strandings seems to be increasing in recent years. All the stranded humpback whales were 3.6\u201310.3 meters in length and estimated to be 0\u20136 years old; therefore, they were considered sexually immature. These results indicate that the number of strandings of immature whales is larger than that of mature ones, and this trend agrees with those reported from other regions of the world. Regarding bycatches, we confirmed 5 individuals caught incidentally in a fixed net; however, all such whales were able to get out from the net alive on their own or with help within a week. Comparison of the photographs of the ventral fluke pattern and shape of these bycatch whales and those of 1563 individuals recorded from around Okinawa after the release of the above 5 whales indicates that 3 out of 5 whales were sighted again around Okinawa Island after the release and confirmed to be alive.", "subitem_description_type": "Other"}, {"subitem_description": "\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "en", "subitem_1522300316516": "Ryukyu University Museum, Fujukan"}, {"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u8cc7\u6599\u9928 (\u98a8\u6a39\u9928)"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/46833"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "2187-6657"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "en", "subitem_1522650091861": "Fauna Ryukyuana"}]}, "item_1617187056579": {"attribute_name": "Bibliographic Information", "attribute_value_mlt": [{"bibliographicPageEnd": "22", "bibliographicPageStart": "13", "bibliographicVolumeNumber": "49"}]}, "item_1617258105262": {"attribute_name": "Resource Type", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_1617265215918": {"attribute_name": "Version Type", "attribute_value_mlt": [{"subitem_1522305645492": "VoR", "subitem_1600292170262": "http://purl.org/coar/version/c_970fb48d4fbd8a85"}]}, "item_1617353299429": {"attribute_name": "Relation", "attribute_value_mlt": [{"subitem_1522306287251": {"subitem_1522306382014": "URI", "subitem_1522306436033": "https://fauna-ryukyuana.webnode.jp/"}}]}, "item_1617605131499": {"attribute_name": "File", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "download_preview_message": "", "file_order": 0, "filename": "51-5_Corrigendum.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2011069/files/51-5_Corrigendum.pdf"}, "version_id": "82943c89-f5ef-4332-83a5-d4fd8c34c11e"}, {"accessrole": "open_access", "download_preview_message": "", "file_order": 1, "filename": "49-2_Okabe_etal.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2011069/files/49-2_Okabe_etal.pdf"}, "version_id": "a7ffd791-af9d-4485-b36d-5f1c3ffc2983"}]}, "item_title": "1996\u20132018\u5e74\u306e\u6c96\u7e04\u5cf6\u5468\u8fba\u306b\u304a\u3051\u308b\u30b6\u30c8\u30a6\u30af\u30b8\u30e9\u306e\u6f02\u7740\u304a\u3088\u3073\u6df7\u7372", "item_type_id": "15", "owner": "1", "path": ["1642838192499", "1642838412624"], "permalink_uri": "http://hdl.handle.net/20.500.12000/46833", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2020-10-06"}, "publish_date": "2020-10-06", "publish_status": "0", "recid": "2011069", "relation": {}, "relation_version_is_last": true, "title": ["1996\u20132018\u5e74\u306e\u6c96\u7e04\u5cf6\u5468\u8fba\u306b\u304a\u3051\u308b\u30b6\u30c8\u30a6\u30af\u30b8\u30e9\u306e\u6f02\u7740\u304a\u3088\u3073\u6df7\u7372"], "weko_shared_id": -1}
