The relationship between the volume of water filtered and the wire length actually paid out was studied, employing 123 examples in good sampling conditions at various times and in places of the Japan Sea. The regression equation obtained was, V =- 15.46+0.2487 l where V: volume of water filtered (m3) when the net was hauled with l (m) length of wire. The t-test revealed that all the intercept, regression coefficients and correlation coefficients (0. 864) are significant (p<0.01). It is shown that the filtering efficiency of the net is 0.916 in general in the present examination. It is emphasized that the above equation can be applied to estimating the volume of water filtered when a flow-meter is not equipped to the net and the filtered water volume cannot be calculated directly. A table showing wire length/angle-volume of water relation is given, assuming filtering efficiencies of 100, 90 and 75%.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Sea Regional Fisheries Research Laboratory","subitem_publisher_language":"en"}]},"item_10002_radio_30":{"attribute_name":"item_10002_radio_30","attribute_value_mlt":[{"subitem_radio_item":"吉田","subitem_radio_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"js_k_33_159_162","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/2010263734","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00186380","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0021-4620","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":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Morioka, Taizo","creatorNameLang":"en"},{"creatorName":"森岡, 泰三","creatorNameLang":"ja"},{"creatorName":"モリオカ, タイゾウ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Morioka","familyNameLang":"en"},{"familyName":"森岡","familyNameLang":"ja"},{"familyName":"モリオカ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Taizo","givenNameLang":"en"},{"givenName":"泰三","givenNameLang":"ja"},{"givenName":"タイゾウ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"822","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"40443395","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=40443395"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Norpacネット鉛直びき採集におけるワイヤ長とろ過水量との関係","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Norpacネット鉛直びき採集におけるワイヤ長とろ過水量との関係","subitem_title_language":"ja"},{"subitem_title":"Relationship between the Length of Wire out and the Volume of Water Filtered by the Norpac Net Vertical Haulings","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951426151"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-23"},"publish_date":"2024-04-23","publish_status":"0","recid":"2002546","relation_version_is_last":true,"title":["Norpacネット鉛直びき採集におけるワイヤ長とろ過水量との関係"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-03-27T23:55:52.554364+00:00"}
