Tiny plastic balls and strips of tape were put in the current of a mean velocity of 69.8cm/sec. and traced. Measurement of the flow direction and speed was made by a three-dimensional electro-magnetic current meter. As soon as the balls reached the netting they slid along it and deposited in the bucket. While the strips adhered to the netting at the reaching and did not move. The stream kept straight from the mouth to the end of the net at or near the central axis of it, and somewhat unstable at the locations closer to the netting. The current velocity inside the net A was higher than that in front of the mouth. In the net B, however, the current velocity was higher in the space from the middle to the end of the cone than that in other place, probably because of so-called net suction phenomenon.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"プランクトンネット内に連行された生物が,どのような流路を経て網地に達し,その後どのような状態にあるのかを把握する手掛かりを得るために,トラック型還流水槽を用いて,開口比2.0のAネットと5.0のBネットを比較検討した.このため,球とテープを流してそれらの流程を観察し,また,三軸電磁流速計を用いて流向流速を測定した.網口から連行された球は網地に達した後は網地の表面を滑って網裾付近に集まる.一方,テープは網地に達したらその付近に張り付き,球のように網地の表面を移動しない.三軸電磁流速計による測定では,ネットの中心線付近の水流は網口から網裾方向に向けて直線状に流れており,網地の内面近くの流向は多少不安定なところがみられた.Aネットではネット前面よりネット内部の流れが遅いが,Bネットではネット前面の流れよりネット円錐部中央より後力における流れが速い.これはネットの吸引現象によるものと考えられる.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"西海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Seikai 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":"snf_k_64_83","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/2010371419","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00393385","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0582-415X","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":"Kozasa, Etsuji","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"小笹, 悦二","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"コザサ, エツジ","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Kozasa","familyNameLang":"en"},{"familyName":"小笹","familyNameLang":"ja"},{"familyName":"コザサ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Etsuji","givenNameLang":"en"},{"givenName":"悦二","givenNameLang":"ja"},{"givenName":"エツジ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3426","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kimoto, Katsunori","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"木元, 克則","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"キモト, カツノリ","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Kimoto","familyNameLang":"en"},{"familyName":"木元","familyNameLang":"ja"},{"familyName":"キモト","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Katsunori","givenNameLang":"en"},{"givenName":"克則","givenNameLang":"ja"},{"givenName":"カツノリ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"1871","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"30371991","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=30371991"}]}]},"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":"開口比の異なる2種類のプランクトンネット内の水流","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"開口比の異なる2種類のプランクトンネット内の水流","subitem_title_language":"ja"},{"subitem_title":"Water-Flow Pattern in Plankton Nets with Different Open Area Rations","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951205967"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-20"},"publish_date":"2024-06-20","publish_status":"0","recid":"2008210","relation_version_is_last":true,"title":["開口比の異なる2種類のプランクトンネット内の水流"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-06-11T04:40:39.194113+00:00"}
