Materials were caught by beam trawl and seine at stations located in relatively deeper waters in the bay and some supplementary collections were made in shallow waters including estuaries. In this report, a list of the species caught and the seasonal changes in the species composition are reported. 1) Sixty species of macrurans of three sections were identified. Families and the number of species in each family are; Section Penaeidea - 22 species of 3 families: Sergestidae (1 sp.), Luciferidae (2 spp.), and Penaeidae (19 spp.). Section Caridea - 37 species of 9 families: Pandalidae (2 spp.), Pasiphaeidae (2 spp.), Alpheidae (5 spp.), Ogyrididae (1 sp.), Hippolytidae (10 spp.), Processidae (5 spp.), Palaemonidae (4 spp.), Rhynchocinetidae (3 spp.), and Crangonidae (5 spp.). Section Palinura - one species of one family: Scyllaridae (1 sp.). 2) Fifty seven species of brachyurans of five subsections were identified. Families and the number of species in each family are; Subsection Oxystomata - 12 species of 3 families: Dorippidae (2 spp.), Leucosidae (9 spp.), and Calappidae (1 sp.). Subsection Dromiacea-two species of one family: Dromiidae (2 spp.). Subsection Oxyrhyncha -11 species of three families: Hymenosomatidae (2 spp.), Majidae (8 spp.), and Parthenopidae (1 sp.). Subsection Corystoidea - two species of one family: Corystidae (2 spp.). Subsection Brachyrhyncha - 30 species of 6 families : Portunidae (12 spp.), Xanthidae (5 spp.), Goneplacidae (3 spp.), Pinnotheridae (3 spp.), Ogypodidae (2 spp.), and Grapsidae (5 spp.). 3) Total number of species was smaller in winter and larger in summer through autumn both in macrurans and brachyurans. In macrurans it does not increase much, and seasonal change is small, while in brachyurans the number of species during summer and autumn is three times as large as that during winter, thus the seasonal change is drastic. Total number of the individuals of macrurans is relatively small during winter months, but increases greatly during summer and autumn, showing drastic seasonal change. The seasonal shange in brachyurans is almost the same as that of macrurans, relatively small in winter months and increases greatly during summer and autumn months. 4) The most dominant species of macrurans is Crangon affinis which consists about 70 percent of the entire macruran individuals. The next dominant are Metapenaeopsis barbata, M. acclivis, M. dalei, Trachypenaeus curvirostris and Parapenaeopsis tenella. About one half of all the species of macrurans occur all the year round. The most dominant species of brachyurans is Portunus hastatoides, and the next dominant is Charybdis bimaculata. Small-sized crabs of Portunidae such as two species mentioned above, Charybdis japonica and C. truncata occupy high ranks all around the year.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"油谷湾に出現するエビ·カニ類について,出現種および種組成の季節的変化について考察を行った.エビ類1. エビ類の出現種類数は若干の不明種を含めて,合計60種 確認された. 内訳はクルマエビ族 3科で22種,コエビ族 9科37種,イセエど族1科1種である.2. 出現種類は周年を通じて大きな変化はないが,冬季に少なく,夏季から秋季にかけてやや多い傾向を示し個体数も冬季に少なく夏季から秋季に増加する.3. 湾内における最優占種はエビジャコで年間を通じて総個体数の70%以上を占める,また,エビジャコに次ぐ優占種はアカエビ,トラエビ,キシエビ,サルエビ,スベスベエビ等のクルマエビ科の小型エビ類で,上記5種の年間出現率は個体数にして15%である.周年出現する種は全出現種の半数の30種であった.4. 季節の変化によってエビ類の群集構造も変化するが,多様度指数で比較すると秋季に最も複雑な構造となり,その後段階的に変化して夏季に最も単純化する.しかし夏季の指数は最優占種であるエビジャコの動向に大きく左右される.カニ類1. カニ類の出現種は合計57種確認された.内訳は尖口亜区3科12種,カイカムリ亜区1科2種,尖頭亜区3科11種,ヒゲガニ亜区1科2種,方頭亜区6科30種である.2. 出現種類数は夏季から秋季にかけて多く,冬季から春季は少ないが,その季節間の差が大きく,後者は前者の1/3程度である.3. 優占種はヒメガザミ,次いでフタホシイシガニであるが,周年を通じて個体数順位の上位は上記2種の他にイシガニ,ヒロハイシガニ等ワタリガニ科の小型種で占められる.4. カニ類の群集構造の季節による変化を多様度指数で検討すると,冬~春季が単純群集,夏~秋季が複雑群集となり,季節間の群集構造の変化は明瞭である.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"西海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Seikai Regional Fisheries Research Laboratory","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":"snf_k_56_39","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/2010232902","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00393385","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0582-415X","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":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Kojima, Kikuo","creatorNameLang":"en"},{"creatorName":"小島, 喜久雄","creatorNameLang":"ja"},{"creatorName":"コジマ, キクオ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Kojima","familyNameLang":"en"},{"familyName":"小島","familyNameLang":"ja"},{"familyName":"コジマ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Kikuo","givenNameLang":"en"},{"givenName":"喜久雄","givenNameLang":"ja"},{"givenName":"キクオ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3435","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hanabuchi, Seiko","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"花渕, 靖子","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"ハナブチ, セイコ","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Hanabuchi","familyNameLang":"en"},{"familyName":"花渕","familyNameLang":"ja"},{"familyName":"ハナブチ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Seiko","givenNameLang":"en"},{"givenName":"靖子","givenNameLang":"ja"},{"givenName":"セイコ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3442","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"油谷湾におけるエビ・カニ類の生態学的研究 (1)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"油谷湾におけるエビ・カニ類の生態学的研究 (1)","subitem_title_language":"ja"},{"subitem_title":"Ecological Studies on Decapod Crustacians in Yuya Bay, the Japan Sea (1)","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951205967"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-20"},"publish_date":"2024-06-20","publish_status":"0","recid":"2008247","relation_version_is_last":true,"title":["油谷湾におけるエビ・カニ類の生態学的研究 (1)"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-06-04T06:08:19.425883+00:00"}
