NAFO: Historical collection of annual fisheries catch statistics for flatfish in the Northwest Atlantic during the period 1893-1959

In 2013 the NAFO Secretariat produced a working paper 'A compilation of historical groundfish catch data from the NAFO Regulatory Area 1804-1959' (SCS 14-07). This report was based upon a literature review of documents. The compiled records contained country, scientific name, NAFO fishing area, year and annual catch (metric tons). A nominal latitude and longitude were assigned to each record based upon the NAFO fishing areas definitions access through the Marine regions gazetteer www.marineregions.org Nominal catches are landed weight, for instance gutted, heads-on fish converted to corresponding weight of round fresh fish. Zero catches are not included in this version of the dataset. The original report contains catch statistics dating back to 1804 but many of these earlier records do not reference a defined NAFO fishing subarea.2013年，西北大西洋渔业组织（Northwest Atlantic Fisheries Organization，简称NAFO）秘书处编制了一份工作文件《1804-1959年NAFO管制区历史底层鱼类捕捞数据汇编》（SCS 14-07）。该报告基于文献综述完成。 汇编后的记录涵盖国家、物种学名、NAFO捕捞区域、年份及年度捕捞量（公吨）。每条记录均通过海洋地区地名录（www.marineregions.org）获取的NAFO捕捞区域定义，赋予名义纬度与经度。 名义捕捞量指上岸重量，例如将去内脏、带头部的鱼类换算为对应重量的整鲜鱼。本版数据集未纳入捕捞量为零的记录。 原始报告包含可追溯至1804年的捕捞统计数据，但其中多数早期记录未明确标注具体的NAFO捕捞亚区。
