Each of the systems was equipped with four wired underwater TV cameras, a tickler chain, a depth meter and an odometer. Herding and entry sequences of demersal juvenile fish at the tickler chain, depth and towing distance were recorded with 8-mm video tape recorders. Six species of fish were identified, and the behavior patterns were classified into six types from the records. One of the systems was tested for the probability of the application to determine abundance of demersal juvenile fish.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"桁網のティックラーチェーンに対する底生幼稚魚の逃避，入網行動を評価するため，曳航式底生魚類撮影装置を作成し，試験を行った。映像から魚種の確認，および逃避，入網行動の観察ができ，逃避，入網行動の違いが魚種による採集効率 44 藤田・木元 写真5 逃避するヒラメ（矢印）に違いを与えていると推察された。 Kuipers10）は，φ6mmのステンレス製ティックラーチェーンおよびグラウンドからなるソリ付き桁網によるplaice幼稚魚 の採集効率について，チェーン下方への逃避はないとしている。しかしながら，本調査においては逃避が観察された場合は，ティックラーチェーン下方が大部分を占め，ティックラーチェーンおよびグラウンドの接地性が採集効率向上に重要であることが確認された。その結果，本装置は映像による他 の分布量調査手法に比べ，下記の特徴を持つことが確認された。①複数のカメラを取り付けることにより，広い観察幅で，魚種判別，全長測定を行える。②ティックラーチェーンにより，特に異体類幼稚魚のように潜砂している個体を駆りたてて撮影できる。③海底からカメラまでの距離が一定であり，かつカメラが 真下を向いているので魚が大きく離底しない限り全長測 定が容易である。カメラによる観察と桁網による採集でヒラメの平均全長が異なった理由としては，調査地点の違いによる分布の偏り，小さなヒラメほどカメラでは発見されにくい可能性および映像による測定精度の問題等が挙げられる。また，分布量評価のためには，計数率（映像により計数できた個体数／真の分 布数）の算出が不可欠である。これらについては，今後改良 を加え，実用化を図る予定である。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産工学研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"National Research Institute of Fisheries Engineering","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":"nrife_g_21_41","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/2010600362","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN1056052X","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"1341-8750","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":"Fujita, Kaoru","creatorNameLang":"en","creatorNameType":"Organizational"},{"creatorName":"藤田, 薫","creatorNameLang":"ja","creatorNameType":"Organizational"},{"creatorName":"フジタ, カオル","creatorNameLang":"ja-Kana","creatorNameType":"Organizational"}],"familyNames":[{"familyName":"Fujita","familyNameLang":"en"},{"familyName":"藤田","familyNameLang":"ja"},{"familyName":"フジタ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Kaoru","givenNameLang":"en"},{"givenName":"薫","givenNameLang":"ja"},{"givenName":"カオル","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"612","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"50372074","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=50372074"}]},{"creatorNames":[{"creatorName":"Kimoto, Katsunori","creatorNameLang":"en","creatorNameType":"Organizational"},{"creatorName":"木元, 克則","creatorNameLang":"ja","creatorNameType":"Organizational"},{"creatorName":"キモト, カツノリ","creatorNameLang":"ja-Kana","creatorNameType":"Organizational"}],"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_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Underwater TV camera;
