Along the coast of the bay, several industrial areas are in operation and are being increased in size. Two big harbours are being developed for this industrial growth in the bay. Accordingly, vessels passing through the mouth of Shimabara Bay will increase in size and in number year by year and importance of Hayasaki Seto as a traffic lane will rise. A series of radar and visual observations on sea traffic was made on board the R/V Kakusui on waters off Futae Fishing Port of Amakusa Is. over 128 hrs on two occasions in August and September 1982. Throughout the observation, shipborne radar was operated continuously and sights on a radar screen were recorded with a 35 mm camera. Some results from this observation are as follows: i) Generally, almost all vessels pass in daytime. Oil-tankers and cargo-ships are dominant in number accounting for 80% of the total passing vessels and sand-carriers are the third at 8%. Almost transversing vessels (98%) are inter-island car-cariers. ii) Passing speeds of oil-tankers or cargo-ships are estimated at about 10 knots mean. Cruising speeds of fishing boats around 5 G/T are relatively high at 11 knots mean and 24 knots at maximum. iii) A regular lane for passing vessels is ranged within 0.4～1.2 n.m. southward of Setsumezaki and 0.2～1.2 n.m. northward of Gotsashb iv) The number of fishing boats in operation is greater in daytime than at night in this passage and they are particularly concentrated around the slack water time. However, these fishing boats do not disturb sea traffic, because they are scattered in small groups and are not so dense.","subitem_description_type":"Abstract"},{"subitem_description":"1) 早崎瀬戸の通航船舶量は昼間に多く夜間は著しく少ない.とくに5000総トン以上の大型船は原則的に昼間通過する. 2) 種類別にみると,早崎瀬戸の通過船舶はタンカーおよび貨物船が80%を占め,次いで砂利運搬が8%にも達している.この砂利運搬船が多いのが大きな特徴であろう.また,当瀬戸を横切る南北航路では,カーフェリーが98%を占めている. 3) 通航船舶の平均対地速力は,タンカーおよび貨物船では約10ノットで,漁船は約11ノットと高速で最高24ノットの船速も観測された. 4) 主たる通峡航路は,瀬詰埼の南0.4～1.2マイルおよび五通礁の北0.2～1.2マイルの幅であるが,東航の場合西航船よりやや南寄りを航行する傾向がある. 5) 島原湾南部海域に関連する登録漁船数は約6000隻の多きに達するが,その稼働率は2～5%と考えられるから,実際の出漁漁船数は実数に比べて著しく少ない. 6) 漁船は一般に塊状に分布し,夜間は昼間に比し著しく少ない.一方,この海域の漁獲は年々減少の傾向にあるから,早崎瀬戸通航船舶に支障を来すほど多数の漁船団は今後当分の間出現しないと考えられる.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学水産学部研究報告, v.55, pp.39-49; 1984","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"39422","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Shibata, Keishi"}]},{"nameIdentifiers":[{"nameIdentifier":"39423","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Mano, Suehiro"}]},{"nameIdentifiers":[{"nameIdentifier":"39424","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Takayama, Hisaaki"}]}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学水産学部"}]},"item_3_relation_29":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"40002770811","subitem_relation_type_select":"NAID"}}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00178473","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05471427","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"柴田, 恵司"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"真野, 季弘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"高山, 久明"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-22"}],"displaytype":"detail","filename":"suisan55_039.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"suisan55_039.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/9754/files/suisan55_039.pdf"},"version_id":"6eb4729e-72db-40e6-9700-9fa5b3c9784a"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"早崎瀬戸における船舶交通量と漁船の操業実態について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"早崎瀬戸における船舶交通量と漁船の操業実態について"}]},"item_type_id":"3","owner":"2","path":["727"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-01-29"},"publish_date":"2013-01-29","publish_status":"0","recid":"9754","relation_version_is_last":true,"title":["早崎瀬戸における船舶交通量と漁船の操業実態について"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T01:38:31.171632+00:00"}
