It causes great damage to marine and fisheries industries. This paper discusses some of the biology of marine biofouling organisms and the relationship between marine biofouling and fisheries. Special attention is given to the damage caused by marine biofouling to the fin-fish cage culture industries of Hong Kong.\nAt present, approximately 5,000 species of marine biofouling organisms occur in the\nworld, of which 2,000 species are recorded. In the coastal water of China, there are about 700 recorded species. About 250 biofouling organisms are found in Hong Kong.\nThe dominant species are barnacles, bryozoans, polychaetes, sea squirts (ascidians) and bivalves. The main biofouling of fish cages in Hong Kong is caused by the polychaete Hydroides elegans, sea squirts Styela plicata and S.canopus, oyster Ostrea glomerata,\nbarnacles Balanus reticulatus and B.trigonus.\nDepending on habitat and sea water temperatures, marine biofouling has obvious\nseasonal fluctuations in growth and occurrence. Marine fouling organisms occur on the fish cages in Hong Kong all the year round, but April to June is the predominant season of the occurrence of Hydroides elegans. During this period, small mesh nets will become completely obstructed by this animal. Oyster Ostrea spp., barnacles Balanus reticulatus and B.trigonus and the sea squirts Styela plicata and S.canopus occur in the months of June to November. From November to March the main fouling species is the bryozoan Bugula neritina.\nIn Hong Kong because of marine fouling, fish cage nets need to be changed about\nevery 1-3 months. The biofouling organisms (such as H.elegans) which attack nets,\ncan be sprayed with sea water which will clean the net. But those with calcareous substances such as Ostrea and Balanus must be cleaned by sunlight and manpower. At present, antifouling paints are being tested on fish cage nets in China, Japan and Hong Kong. However, toxic substances such as TBTO and TBTF from these paints may\naccumulate in the fish with direct or indirect effects on human beings. So their use requires further investigation.","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"}]},"item_7_relation_32":{"attribute_name":"関連（relation）","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://hdl.handle.net/10232/16218"}]},{"subitem_relation_name":[{"subitem_relation_name_text":"http://hdl.handle.net/10232/16219"}]},{"subitem_relation_name":[{"subitem_relation_name_text":"http://hdl.handle.net/10232/16220"}]},{"subitem_relation_name":[{"subitem_relation_name_text":"http://hdl.handle.net/10232/16221"}]},{"subitem_relation_name":[{"subitem_relation_name_text":"http://hdl.handle.net/10232/16222"}]},{"subitem_relation_name":[{"subitem_relation_name_text":"http://hdl.handle.net/10232/16223"}]},{"subitem_relation_name":[{"subitem_relation_name_text":"http://hdl.handle.net/10232/16224"}]},{"subitem_relation_name":[{"subitem_relation_name_text":"http://hdl.handle.net/10232/16225"}]}]},"item_7_relation_33":{"attribute_name":"関連（isVersionOf）","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://hdl.handle.net/10232/16217","subitem_relation_type_select":"URI"}}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"02892707","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN10030752","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"663","subitem_subject_scheme":"NDC"},{"subitem_subject":"452","subitem_subject_scheme":"NDC"}]},"item_7_text_24":{"attribute_name":"公開者よみ","attribute_value_mlt":[{"subitem_text_value":"カゴシマ ダイガク"}]},"item_7_text_25":{"attribute_name":"公開者別名","attribute_value_mlt":[{"subitem_text_value":"Kagoshima University"}]},"item_7_text_44":{"attribute_name":"備考","attribute_value_mlt":[{"subitem_text_value":"Title page: http://hdl.handle.net/10232/16217, Foreword: http://hdl.handle.net/10232/16218, Preface: http://hdl.handle.net/10232/16219, 本文: http://hdl.handle.net/10232/16220, http://hdl.handle.net/10232/16221, http://hdl.handle.net/10232/16222, http://hdl.handle.net/10232/16223, http://hdl.handle.net/10232/16224, http://hdl.handle.net/10232/16225"}]},"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":"TSENG, W.Y."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HUANG, Z.K."}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-28"}],"displaytype":"detail","filename":"AN10030752_v13_p42-55.pdf","filesize":[{"value":"5.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN10030752_v13_p42-55.pdf","url":"https://ir.kagoshima-u.ac.jp/record/5224/files/AN10030752_v13_p42-55.pdf"},"version_id":"5cf39018-86b4-444d-968a-0ca602b2906a"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Marine Biofouling and Fisheries","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Marine Biofouling and Fisheries"}]},"item_type_id":"7","owner":"3","path":["94","5414"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-03-06"},"publish_date":"2013-03-06","publish_status":"0","recid":"5224","relation_version_is_last":true,"title":["Marine Biofouling and Fisheries"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-09-12T06:34:25.140808+00:00"}
