The trawl net codend used was made of diamond mesh net with a legal minimum mesh opening size of 54 mm (mesh length of 66 mm). The cover net with a mesh opening of 18 mm (or 10.3 mm depending on the research year) was attached to the codend. For each of the 20 fish species and two squid species, we pooled data of hauls where body size for the whole catch was measured without subsampling to obtain the body size compositions of both of the codend and the cover net. The maximum likelihood method was performed for estimation of parameters in the logistic curve equation representing the codend selection curve. For 18 fish species (excluding Trichiurus japonicus and Muraenesox cinereus), we examined the relationship of the obtained selection parameters [l50, length of 50% retention and SR, selection range (= l75 - l25)] to the fish body shape. We demonstrated that fish species with a smaller ratio of body height/width to body size (i.e. more slender body type) show a tendency of larger values of l50 and SR. Furthermore, by comparing the l50 of each fish species with the reproductive parameters such as minimum maturity length, we examined the sustainability of the resources based on the minimum mesh size regulation."},{"subitem_description":"東シナ海の魚類 20 種とイカ類 2 種に対する最小規制目合(目合内径 54 mm)のコッドエンドを持つトロール網のコッドエンド選択性曲線を,カバーネット装着操業試験の結果から求めた。魚類 18 種(タチウオとハモを除く)の選択性パラメータ(50% 選択体長と選択レンジ)と魚体型の関係から,細長い体型の魚種ほど網目を抜けやすくかつ選択性が鋭くないことを示した。さらに,50% 選択体長と最小成熟体長など再生産パラメータを比較することで,単一目合のコッドエンド選択によって複数種を対象とした資源利用の持続性を検討した。"}]},"item_3_description_63":{"attribute_name":"研究課題番号","attribute_value_mlt":[{"subitem_description":"16K07837"}]},"item_3_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer"}]},"item_3_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s12562-018-1270-x","subitem_relation_type_select":"DOI"}}]},"item_3_relation_13":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Publisher's Version/PDF"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1007/s12562-018-1270-x","subitem_relation_type_select":"DOI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"日本水産学会"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://jsfs.jp/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"KAKEN研究課題: 底曳網の選択性パラメータにおける変動要因と資源管理におけるリスク評価"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-16K07837/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"研究代表者: 東海正 (東京海洋大学)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://nrid.nii.ac.jp/ja/nrid/1000030237044/","subitem_relation_type_select":"URI"}}]},"item_3_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 2018 Japanese Society of Fisheries Science and Springer Japan.
