Catch and effort statistics for jigging boat fishery in 1979 were compiled by ten day basis. Some linear regression methods of De Lury type estimator and a nonlinear regression method were applied to the data. Total mortality coefficient during two months, September and October, was estimated to be 0.14-0.15 per decade. Although a value of 0.1495/decade was estimated as natural mortality coefficient by nonlinear regression method, it was considered too high. Judging from other biological information and some previous estimates for similar species, natural mortality coefficient of this species seemed to be less than 0.07/decade and thus rate of exploitation during two months exceeds 30 percent.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"北西太平洋海域におけるアカイカの資源特性値を推定した。1979年9月~10月の旬別漁獲尾数と基準化した努力量を計算し,De Lury 流の線型回帰による方法と非線型回帰による同時推定法を応用した。各手法による結果から判断すると、この2ヵ月間の全減少係数は0.14~0.15/旬程度と見積られる。自然死亡係数については後者の方法から M=0.1495/旬が推定されたが,従来の知見と比較すると過大になっていると思われた。従来の種々の知見を併せ考えると,自然死亡係数はかなり小さく,0.07/旬前後以下とみなされ,従ってこの期間の漁獲率は30%を越えるものと見積られる。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"北海道区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Hokkaido Regional Fisheries Research Laboratory","subitem_publisher_language":"en"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"hnf_k_47_1","subitem_relation_type_select":"Local"}}]},"item_10002_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/2010261309","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00124758","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0513-2541","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"村田, 守","creatorNameLang":"ja"},{"creatorName":"ムラタ, マモル","creatorNameLang":"ja-Kana"},{"creatorName":"Murata, Mamoru","creatorNameLang":"en"}],"familyNames":[{"familyName":"村田","familyNameLang":"ja"},{"familyName":"ムラタ","familyNameLang":"ja-Kana"},{"familyName":"Murata","familyNameLang":"en"}],"givenNames":[{"givenName":"守","givenNameLang":"ja"},{"givenName":"マモル","givenNameLang":"ja-Kana"},{"givenName":"Mamoru","givenNameLang":"en"}]},{"creatorNames":[{"creatorName":"嶋津, 靖彦","creatorNameLang":"ja"},{"creatorName":"シマヅ, ヤスヒコ","creatorNameLang":"ja-Kana"},{"creatorName":"Shimazu, Yasuhiko","creatorNameLang":"en"}],"familyNames":[{"familyName":"嶋津","familyNameLang":"ja"},{"familyName":"シマヅ","familyNameLang":"ja-Kana"},{"familyName":"Shimazu","familyNameLang":"en"}],"givenNames":[{"givenName":"靖彦","givenNameLang":"ja"},{"givenName":"ヤスヒコ","givenNameLang":"ja-Kana"},{"givenName":"Yasuhiko","givenNameLang":"en"}]}]},"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":"北西太平洋海域におけるアカイカの資源特性値について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"北西太平洋海域におけるアカイカの資源特性値について","subitem_title_language":"ja"},{"subitem_title":"On Some Population Parameters of Flying Squid, Ommastrephes bartrami (LESUEUR) in the Northwest Pacific","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716950587014"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-08"},"publish_date":"2024-04-08","publish_status":"0","recid":"2001758","relation_version_is_last":true,"title":["北西太平洋海域におけるアカイカの資源特性値について"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-01-21T02:25:32.043920+00:00"}
