Eighty-six fish species were collected and P. herzensteini, fivespot flounder Pseudorhombus pentophthalmus, croaker Argyrosomus argentatus and bastard halibut Paralichthys olivaceus were dominant. Seasonal changes in habitat of roundnose flounder Eopsetta grigorjewi and willowy flounder Tanakius kitaharai were similar to that of P. herzensteini but they were less abundant. The most important food organisms of P. herzensteini were polychaete annelids and there was a considerable difference in diet between P. herzensteini and other dominant fishes. Interspecific competition between P. herzensteini and other dominant fishes appears to be weakend by changing their distribution and main diet.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"1982年3月から1982年11月までの期間に4回,新潟県北部沿岸域において板曳網による漁獲試験を行い,底生魚類の分布関係および食物関係を検討した.1.4回の調査で48科75属86種の魚類が採集された.出現種数は3月が60種で最も多く,他の月は45種から48種であり大きな違いはみられない.底生魚類群集の種多様度は3月に最も高く,9月から11月にかけて低下した.また,5月,9月および11月では水深が増すにつれて種多様度が低下する傾向がみられた.2.4回の調査すべてで採集された魚種は27種で,そのうちタマガンゾウビラメ,マガレイ,シログチおよびヒラメの4魚種は個体数組成ならびに重量組成で常に上位10種に含まれていた.とくにマガレイは4回の調査の累計で個体数組成および重量組成が10%を超える唯一の魚種であり,当海域における底生魚類の優占種の一つとして重要な地位を占めているものと考えられる.3. 当海域における主要構成種の分布水深の月別変化は5型に区分された.マガレイと分布域の重複度が大きな魚種はムシガレイおよびヤナギムシガレイであったが,これら2種の採集個体数は少なかった.4. 当海域のマガレイは多毛類を餌料基盤としているが,食物を競合する主要魚種はほとんどみられず,他魚種との餌生物をめぐる種間競争は比較的弱いものと考えられる.以上の結果をまとめると,マガレイは当海域の底生魚類群集内で,他魚種と生息水深や利用する餌生物が相違していることから種間の競合が緩和され,これが優占種としての生態的地位を維持する重要な一因となり,マクロベントスから魚類にいたるェネルギー転流において重要な役割を果たしていると考えられた.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Sea National Fisheries Research Institute","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":"js_k_41_11_26","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/2010501366","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":"AN00186380","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0021-4620","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":[{"affiliationNames":[{"affiliationName":"北海道立中央水産試験場","affiliationNameLang":"ja"},{"affiliationName":"ホッカイドウリツチュウオウスイサンシケンジョウ","affiliationNameLang":"ja-Kana"},{"affiliationName":"Hokkaido Central Fisheries Experimental Station","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"富永, 修","creatorNameLang":"ja"},{"creatorName":"トミナガ, オサム","creatorNameLang":"ja-Kana"},{"creatorName":"Tominaga, Osamu","creatorNameLang":"en"}],"familyNames":[{"familyName":"富永","familyNameLang":"ja"},{"familyName":"トミナガ","familyNameLang":"ja-Kana"},{"familyName":"Tominaga","familyNameLang":"en"}],"givenNames":[{"givenName":"修","givenNameLang":"ja"},{"givenName":"オサム","givenNameLang":"ja-Kana"},{"givenName":"Osamu","givenNameLang":"en"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Pleuronectes herzensteini; demersal fishes; interspecific competition; food organisms; distribution","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"新潟県北部沿岸域におけるマガレイと底生魚類の種間関係","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"新潟県北部沿岸域におけるマガレイと底生魚類の種間関係","subitem_title_language":"ja"},{"subitem_title":"Interspecific Relationship between Brown Sole Pleuronectes herzensteini and Other Demersal Fishes in the Coastal Waters of Northern Niigata Prefecture","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951426151"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-23"},"publish_date":"2024-04-23","publish_status":"0","recid":"2002478","relation_version_is_last":true,"title":["新潟県北部沿岸域におけるマガレイと底生魚類の種間関係"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-02-13T07:02:18.282994+00:00"}
