This data series starts with the 1969/70 season, but catches were very small before that. Total catches have fluctuated greatly, reflecting several distinct phases in the fishery, initially mainly on fish (Notothenia and Chaenocephalus), but with rapid increases in krill since 1978. Total catches were over half a million t in the 1979/80 season. For recent years complete data are available on catches by species and by subarea, but the more detailed data (including statistics of fishing effort) required for stock assessment are not available for some of the biggest fishing countries. As a result, reliable assessments of the state of the stocks cannot be made, but the historical patterns suggest that the large catches of fish represented the removals of accumulated stocks, and that only a relatively small annual catch can be sustained. No conclusions can be reached from the short period of significant krill catches, although the preliminary reports from the FIBEX surveys suggest that current catches have been only a small proportion of the standing stock. If the fish stocks have indeed been heavily fished, then management measures should be considered. This will require examination of the objectives of the measures (a pattern of \"pulse fishing\" may be more attractive than a steady but low annual catch), of the arrangements for providing scientific advice, and of the type of measures to be introduced (a limit on the number of vessels operating may be better than attempting to set a Total Allowable Catch).","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Fisheries, FAO"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1983-07-01"}],"displaytype":"detail","filename":"KJ00000012082.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"url":"https://nipr.repo.nii.ac.jp/record/1448/files/KJ00000012082.pdf"},"version_id":"a53358a8-7e00-4214-b251-75fd61a97268"}]},"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":"The development of fisheries and stock assessment of resources in the Southern Ocean","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The development of fisheries and stock assessment of resources in the Southern Ocean","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["381"],"pubdate":{"attribute_name":"公開日","attribute_value":"1983-07-01"},"publish_date":"1983-07-01","publish_status":"0","recid":"1448","relation_version_is_last":true,"title":["The development of fisheries and stock assessment of resources in the Southern Ocean"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:53:39.253957+00:00"}
