Genetic analyses have revealed stock structuring in this species, and genetic variation at calmodulin gene locus (CaM) indicated presence of two genetically separated stocks (north and south) in the Atlantic. In this study, frequency of the bill types was compared between localities, sexes and body size classes, and genetic variation in nuclear and mitochondrial gene loci were compared between the bill types, and genetic differentiation in these loci within and between local samples were investigated. There was no significant difference in the frequency of two bill types among samples from Atlantic, Indian and Pacific Oceans as well as between sexes. No genetic difference between chamber and channel types was observed in all gene loci. In all samples, chamber type was more frequently observed in smaller size class than in larger size class. These suggest that the frequency of the two types is independent of stock structure and sex. Considerably large genetic differentiation at CaM locus was observed between north (north of 20˚N) and south (south of 10˚N) Atlantic samples. On the other hand, differentiation among samples within locality was very little among years (1990 to 1998 in north, and 1994 to 1999 in south). The results of genetic analysis indicated that the north and south Atlantic stocks of swordfish were genetically isolated with little gene flow and migration.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産総合研究センター","subitem_publisher_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"fra_k_7_1","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_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/2010671199","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":"AA11589591","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-9894","subitem_source_identifier_type":"PISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open
