One of the most common fishing methods is longline fishing. However, this method requires the vessel to operate at a constant low speed because the depth of the hook must be kept constant while adjusting the speed of the fishing boat to the tidal current. In addition, because the vessel must maneuver and fish at the same time, automation is desired. Thus, we propose a robotic system that can control the depth of the trap at a constant depth even when the speed of the vessel and the current change, and that can successfully fish without the need for skilled fishermen. Fishing can be conducted regardless of the speed of the vessel, whereas currently it is controlled by the speed of the vessel and the tidal current. Therefore, it may contribute to proposing new fishing methods as well as the existing ones. This can contribute to the shortage of successors to the fishing industry and to the revitalization of the fishing industry.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "MDPI AG", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.20944/preprints202306.1074.v1"}}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Haruhiro Shiraishi", "creatorNameLang": "ja"}, {"creatorName": "Haruhiro Shiraishi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Hajime Shiraishi", "creatorNameLang": "ja"}, {"creatorName": "Hajime Shiraishi", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Development of an Automatic Robot To Save Labor in Longline Fishing", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Development of an Automatic Robot To Save Labor in Longline Fishing", "subitem_title_language": "ja"}, {"subitem_title": "Development of an Automatic Robot To Save Labor in Longline Fishing", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "7", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/7304", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2025-09-01"}, "publish_date": "2025-09-01", "publish_status": "0", "recid": "7304", "relation": {}, "relation_version_is_last": true, "title": ["Development of an Automatic Robot To Save Labor in Longline Fishing"], "weko_shared_id": -1}
