In order to evaluate the detrimental effect of the algal blooms, the effects of three phytoflagellates, Heterocapsa circularisquama, Gymnodinium mikimotoi, and Heterosigma akashiwo on survival of juvenile abalone, Haliotis discus and Sulculus diversicolor were studied in the laboratory. The results demonstrate that H. circularisquama and G. mikimotoi frequently kill both abalone species within 24h at densities > 104 cells/ml accompanied with unusual avoidance behaviors; vigorous contraction of tentacles, escape locomotion, and paralysis of the animals. The raphidophyte species H. akashiwo showed lower detrimental effects compared with the two dinoflagellates.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"有害藻類の赤潮においては,商業的に重要な巻貝の大量斃死が見られ,地域の養殖業に多大な被害を及ぼしている。しかしながら,赤潮生物が巻貝に直接及ぼす影響について,培養株を用いて調べた知見はほとんど見られない。そこで,有害赤潮生物 Heterocapsacircularisquama, Gymnodinium mikimotoi,およびHeterosigma akashiwo のクローン培養株を用いて,クロアワビとトコブシの稚貝の生残等に及ぼす影響を予備的に調べた。クロアワビはH. circularisquama およびG.mikimotoiの暴露によって48時間以内にほとんどすべての個体が斃死した。トコブシもH. circularisquama の暴露によって著しく斃死したが,G.mikimotoi の暴露ではクロアワビと異なりやや耐性が見られた。H. circularisquama および G. mikimotoi の暴露では,試験した貝のいずれもが触角の萎縮,足筋肉のねじれ,逃避行動などの異常行動が数分以内に観察され,極めて毒性が高いことが伺われた。H.akashiwoの暴露では,105cells/mlの濃度を除けば顕著な斃死や拒否反応はあまり観察されなかった。巻貝は二枚貝よりも赤潮に弱い可能性が示唆されたことから,今後商業的に重要な巻貝(アワビやサザエ)への影響が懸念される。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"南西海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Nansei National Fisheries Research Instituite","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":"nnf_k_31_19","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/2010571901","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00181988","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0388-841X","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":"松山, 幸彦","creatorNameLang":"ja"}],"familyNames":[{"familyName":"松山","familyNameLang":"ja"}],"givenNames":[{"givenName":"幸彦","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"小泉, 喜嗣","creatorNameLang":"ja"}],"familyNames":[{"familyName":"小泉","familyNameLang":"ja"}],"givenNames":[{"givenName":"喜嗣","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"内田, 卓志","creatorNameLang":"ja"}],"familyNames":[{"familyName":"内田","familyNameLang":"ja"}],"givenNames":[{"givenName":"卓志","givenNameLang":"ja"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Red tide; Dinoflagellate; Gastropod; Abalone; Mortality","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"有害藻類がアワビ類(クロアワビおよびトコブシ)の生残に及ぼす影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"有害藻類がアワビ類(クロアワビおよびトコブシ)の生残に及ぼす影響","subitem_title_language":"ja"},{"subitem_title":"Effect of Harmful Phytoplankton on the Survival of the Abalones, Haliotis discus and Sulculus diversicolor","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951205920"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-25"},"publish_date":"2024-04-25","publish_status":"0","recid":"2003172","relation_version_is_last":true,"title":["有害藻類がアワビ類(クロアワビおよびトコブシ)の生残に及ぼす影響"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-04-10T01:33:50.909619+00:00"}
