Fishing experiments in fishing grounds were carried out using the original Korean whelk pots (square entrance of 30 cm in diagonal) and improved pots of two types (almost 15 or 10 cm), and the baited crab pots used in the Japanese beni-zuwai crab fisheries. The original pots caught both sexes but no immature females. Most males were smaller than 100 mm in carapace width (CW), and the ratio of immature males was higher than for the Japanese crab pots. The pots of 15 cm entrance effectively avoided catching larger male crabs (estimated size at 50% selectivity was 88.2 mm CW) without reducing the catch rate of whelks or adult female crabs. In the pots of 10 cm entrance, the selectivity of male crabs was 0.34 at most compared with the original pots; however, they failed to catch large whelk. The effect of pots of 10 cm entrance on the female crab catch remains unclear because few female crabs were caught in this study. Applications of these improvements to fisheries were discussed.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"輯国製バイ籠によるベニズワイの混獲防止を目的として，細工をしていない原型籠（入口部最大30cm四方），細工 l籠（同 15cm)，細工 2籠（同 10cm) を通常のベニズワイかご漁業の幹縄に装着し，採集調査を行った。原型籠は甲幅 100mmを超えるベニズワイは漁獲されにくく，カニ籠に比べて未成体個体の割合が高かった。細工1籠には大型雄の混獲は防ぐ効果が認められたが (50%選択甲幅 88.2mm)，雌およびバイ類の漁獲には影響しなかった。細工 2籠では，ベニズワイ雄の選択率が最大でも0.34と大幅に混獲が減少したものの，大型バイ類の漁獲も減少した。以上の細工について実際の漁業への適用について議論した。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産研究・教育機構","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Fisheries Research and Education Agency","subitem_publisher_language":"en"}]},"item_10001_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"fra_t_11_2_39","subitem_relation_type_select":"Local"}}]},"item_10001_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/2010928464","subitem_relation_type_select":"URI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12359338","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1883-2253","subitem_source_identifier_type":"PISSN"}]},"item_10001_version_type_20":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"養松, 郁子","creatorNameLang":"ja"}],"familyNames":[{"familyName":"養松","familyNameLang":"ja"}],"givenNames":[{"givenName":"郁子","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"廣瀬, 太郎","creatorNameLang":"ja"}],"familyNames":[{"familyName":"廣瀬","familyNameLang":"ja"}],"givenNames":[{"givenName":"太郎","givenNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-08-06"}],"filename":"fra_t_11_2_39.pdf","format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010609/files/fra_t_11_2_39.pdf"},"version_id":"c267d22a-98ac-404e-b9cc-7c1c2c0052b6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"バイ籠; ズワイガニ類; 混獲; 日韓暫定水域","subitem_subject_language":"ja","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"韓国製バイ籠によるベニズワイ漁獲特性と混獲防止策の検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"韓国製バイ籠によるベニズワイ漁獲特性と混獲防止策の検討","subitem_title_language":"ja"},{"subitem_title":"Characteristics of bycatch of Korean baited whelk pots for beni-zuwai crab, Chionoecetes japonicus, and some pot improvements to reduce the bycatch","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"10","path":["1723085690263"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-08-06"},"publish_date":"2024-08-06","publish_status":"0","recid":"2010609","relation_version_is_last":true,"title":["韓国製バイ籠によるベニズワイ漁獲特性と混獲防止策の検討"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-09-05T08:41:36.601634+00:00"}
