the unevenness of the stone surface perforations upon the stone surface, cracks and fissures of the stones.\n2) In case of the concrete block reef, when the reefs were submerged in a scattered condition, the gathering effect was noted to be quite negligible; but when they were submerged in a from of gathering consisting of from 3 to 5 individuals,\nthe effect was noted to be eminent; especially big effect was noted in the case in which the distance between the gatherings was set within the width of effect-space,\nnamely, when the distance between the gathered concrete blocks was kept within the width counting more or less than 2 m.\n3) In case of the sunken boat reef, the highest gathering effect, especially about\nthe large and middle siged fish, was noted in the hold of the sunken boat which was made open at the upper port and left lidless.\nAnd the effect was promoted further more when the sunken boat was supplied with stanchions on the side-wall, or when some unevenness was supplied on the side-wall itself vertically.\n4) Concerning the width of the effective space, in case of the bottom fish, it was noted to be 0.5~2 m in height and 0.5~3 m in width, but when there was a flowing\ntide, it was made widened at the upper part of the tide, and at night it was the height that was enlarged.\n5) Concerning the kind of the fish related most intimately with the gathering\neffect of the artificial reefs.\nWe may mention the name of the sea urchin (Diadema Setosum) in case of the\nattaching organism, and the name of the cardinal fish (Apogon Semilimeatus) in case of the small siged fish.","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"鹿児島湾口,薩摩半島周辺に設置してある割石,並型コンクリートブロック,沈船の各魚礁について潜水観察を行なった結果,次のような知見を得た。\n1) 割石魚礁の蝟集効果は,魚礁の高さは差程問題とならず,むしろ凹凸,穴場,亀裂のあるものが効果が高い。\n2) 並型コンクリートブロック魚礁では,単体のみでは蝟集効果は極めて低いが,3~5個以上の群体ではその効果は高まり,特に群体間の間隔が有効空間の幅である2m程度ある場合は特に顕著である。\n3) 沈船魚礁では上部がオープンになった蓋なし船倉に大・中型魚の蝟集効果が高く,側壁上のスタンション,垂直方向に凹凸を有する側壁を有する場合はその効果は更に高まる。\n4) 有効空間の広さは底魚の場合,高さが0.5~2m,幅が0.5~3mで潮流のある場合は潮上に幅が広くなり,夜間では高さが高くなる。\n5) 大・中型魚の蝟集効果に最も関係のあるものとして,付着生物では,ガンガゼ,小型魚ではネンブツダイをあげることが出来る。","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0453087X","subitem_source_identifier_type":"PISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040498","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"664","subitem_subject_scheme":"NDC"}]},"item_7_version_type_14":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"肥後, 伸夫","creatorNameLang":"ja"},{"creatorName":"HIGO, Nobio","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4790","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000010041691","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}]},{"creatorNames":[{"creatorName":"長島, 美知男","creatorNameLang":"ja"},{"creatorName":"NAGASHIMA, Michio","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"104600","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-31"}],"displaytype":"detail","filename":"AN00040498_v27-1_p117-130.pdf","filesize":[{"value":"3.8 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"AN00040498_v27-1_p117-130.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/10766/files/AN00040498_v27-1_p117-130.pdf"},"version_id":"44d3d339-550e-439a-9ef6-20cfe6843976"}]},"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":"潜水観察による人工魚礁の実態について II : 鹿児島県薩摩半島周辺海域の場合","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"潜水観察による人工魚礁の実態について II : 鹿児島県薩摩半島周辺海域の場合","subitem_title_language":"ja"},{"subitem_title":"On the Fish Gathering Effect of the Artificial Reefs ascertained by the Diving Observation II : At the Off Sea of the Satsuma Peninsula in Kagoshima Prefecture","subitem_title_language":"en"}]},"item_type_id":"7","owner":"18","path":["40","4830"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-06-16"},"publish_date":"2015-06-16","publish_status":"0","recid":"10766","relation_version_is_last":true,"title":["潜水観察による人工魚礁の実態について II : 鹿児島県薩摩半島周辺海域の場合"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-07-30T01:16:08.251942+00:00"}
