SS and phyto-pigments (chlorophyll a + pheophytin) changed remarkablly, but POS was approximately 1 mg/l throughout the year. Therefor, the seasonal changes of SS almost depended on the inorganic matters. \nCarbon and nitrogen contents, and C/N atomic ratios of SS seasonally changed within the range of 10 to 20 % C, 1 to 3.5 % N and 6.2 to 10 respectively. D430/D665 values in phyto-pigments varied within 2.5 to 4 which suggest high primary production. The assimilation efficiency by the oysters related to the ash contents of SS. The filtration rate was calculated from the growth, the metabolism and the assimilation rate, SS concentratration and carbon contents in SS. \nIt was estimated that the nutritional environment for the oyster ground is of the equibrium between the primary production and the consumption of SS by pearl oysters, judging from the difference between the filtration rate calculated and the actual measurements and the seasonal variation of POS and D430/D665 values.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立真珠研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"National Pearl 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":"pearl_k_2363","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":"日本真珠振興会Archive"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://jp-pearl.com/wp-content/uploads/2018/07/houkoku022.pdf#004","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":"AN00091717","subitem_source_identifier_type":"NCID"}]},"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":"Ito, Katsuhiko","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"伊藤, 克彦","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"イトウ, カツヒコ","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Ito","familyNameLang":"en"},{"familyName":"伊藤","familyNameLang":"ja"},{"familyName":"イトウ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Katsuhiko","givenNameLang":"en"},{"givenName":"克彦","givenNameLang":"ja"},{"givenName":"カツヒコ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3305","nameIdentifierScheme":"WEKO"}]}]},"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":"英虞湾真珠漁場におけるアコヤガイの栄養環境について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"英虞湾真珠漁場におけるアコヤガイの栄養環境について","subitem_title_language":"ja"},{"subitem_title":"Nutritional environment for pearl oyster, Pinctada fucata (Gould) in pearl cultured ground, Ago Bay","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716955633551"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-27"},"publish_date":"2024-06-27","publish_status":"0","recid":"2009101","relation_version_is_last":true,"title":["英虞湾真珠漁場におけるアコヤガイの栄養環境について"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-02-13T02:46:09.800022+00:00"}
