In this paper, it is reported that the specific gravity of gill, mid-gut-gland, marginal zone of mantle and gonad are changed in the various conditions of pearl oyster.\n\n For the determination of the specific gravity copper sulphate method was used. The shell of pearl oyster was opened and very small slices, just half the size of rice grain were cut from the gill, marginal zone of mantle, pallial zone of mantle, adductor muscle, gonad, foot and mid-gut-gland. Blood is sucked up by small injector from the heart. And then blood or each slice was inserted below the surface of the solutions with graded specific gravity from 1.022 to 1.095. The specific gravity of the tissue slice was estimated by the point where it became suspended in the middle layer of a solution of which specific gravity is already calculated by the standardized hydrometer. \n\nAs may be seen from Table 1, which shows the results of this experiment, there was a gradual change of the average specific gravity of the organs in the various conditions. The various physiological conditions are as follows. A; Native pearl oyster which collected under near the Marine Biological Station attached to the National Pearl Research Lab .. B; The pearl oyster is not suited for insertion operation, as the germ cell is filled in its gonad. C; The pearl oyster is suited for operation. D; After spawning, the gonad becomes to narrow to insertion of nucleus. This group of pearl oyster, also, is not suited for operation. E; Enervated pearl oyster. \n\nFig. 1 shows the average changes in the specific gravity of organs during the course of the artificial spawning treatments or enervation. \n\nAs the method of determination of the specific gravity is so simple and does not take much time in the procedure we expect to carry out an extensive experiment in this direction.","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_891","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/2018/04/houkoku008.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":"Uemoto, Haruhiko","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"植本, 東彦","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"ウエモト, ハルヒコ","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Uemoto","familyNameLang":"en"},{"familyName":"植本","familyNameLang":"ja"},{"familyName":"ウエモト","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Haruhiko","givenNameLang":"en"},{"givenName":"東彦","givenNameLang":"ja"},{"givenName":"ハルヒコ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3292","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsujii, Tadashi","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"辻井, 禎","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"ツジイ, タダシ","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Tsujii","familyNameLang":"en"},{"familyName":"辻井","familyNameLang":"ja"},{"familyName":"ツジイ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Tadashi","givenNameLang":"en"},{"givenName":"禎","givenNameLang":"ja"},{"givenName":"タダシ","givenNameLang":"ja-Kana"}]}]},"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":"アコヤガイ軟体部組織の比重について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"アコヤガイ軟体部組織の比重について","subitem_title_language":"ja"},{"subitem_title":"Preliminary note on the specific gravity of organs in the various conditions of pearl oyster.","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":"2009004","relation_version_is_last":true,"title":["アコヤガイ軟体部組織の比重について"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-02-13T02:42:12.875117+00:00"}
