ABARES Fishery Status Reports map data: Southern and Eastern Scalefish and Shark Fishery (SESSF), Scalefish Hook Sector (SSCK): fishing intensity and maximum area fished, annual map data for 2010 to 2022

This dataset presents maps of fishing intensity and maximum area fished of ocean waters within the Southern and Eastern Scalefish and Shark Fishery (SESSF), Scalefish Hook Sector (SSCK). The data were prepared as part of the annual ABARES Fishery Status Reports series, which provides an independent evaluation of the biological and economic status of fish stocks managed solely or jointly by the Australian Government. The data were produced by ABARES from data supplied by the Australian Fisheries Management Authority (AFMA). The data are presented annually, by fishing season which runs from 1 May to 30 April for this fishery. For example, for this fishery, the 2022 season runs from 1 May 2022 to 30 April 2023. The data are polygon vector format, stored in an ESRI file geodatabase, prepared using ArcGIS Desktop ArcMap version 10.8. Fishing intensity is defined as the total fishing effort within a given fishing season, divided by the total area fished in square kilometres. The unit of effort in the Scalefish Hook Sector is measured as the number of hooks deployed. Fishing intensity is presented as classified data in low, medium and high intensity classes. The data attributes include the class, the range of values in the class and the unit of measure. The classification used may vary from year to year, depending on a range of environmental and economic factors. Maximum area fished is defined as the maximum area within which fishing occurred during a given fishing season as polygon cells of one degree of longitude by one degree of latitude (approximately 111 kilometres x 111 kilometres). A cell is included if any fishing activity occurred anywhere within that one degree by one degree cell. Note that cells included in this dataset may also partially cover land. The data supplied by AFMA were filtered to remove activity by fewer than five boats within the area of analysis in order to conform with AFMA’s Information Disclosure Policy (https://www.afma.gov.au/about/fisheries-management-policies/information-disclosure-fisheries-management-paper).

本数据集涵盖南澳与东澳鳞鱼及鲨鱼渔业（Southern and Eastern Scalefish and Shark Fishery, SESSF）下辖鳞鱼钩钓分区（Scalefish Hook Sector, SSCK）内海域的捕捞强度与最大捕捞面积分布图。本数据系澳大利亚农业与资源经济科学局（Australian Bureau of Agricultural and Resource Economics and Sciences, ABARES）年度渔业状况报告系列的组成部分，该系列旨在独立评估由澳大利亚政府单独或联合管理的鱼类种群的生物学与经济学现状。本数据由ABARES基于澳大利亚渔业管理局（Australian Fisheries Management Authority, AFMA）提供的原始数据生成。本数据按捕捞季按年度发布，该渔业的捕捞季为每年5月1日至次年4月30日。例如，该渔业的2022捕捞季为2022年5月1日至2023年4月30日。本数据采用多边形矢量格式，存储于ESRI文件地理数据库（ESRI file geodatabase）中，系使用ArcGIS Desktop ArcMap 10.8版本制作完成。捕捞强度被定义为特定捕捞季内总捕捞努力量除以以平方公里计量的总捕捞面积。鳞鱼钩钓分区的捕捞努力量单位为投放的钓钩数量。捕捞强度以分级数据形式呈现，分为低、中、高三个强度等级。数据属性包含强度等级、该等级的数值区间以及度量单位。所用的分级标准每年可能会根据一系列环境与经济因素进行调整。最大捕捞面积被定义为特定捕捞季内发生捕捞活动的最大区域，以经度1度×纬度1度（约111公里×111公里）的多边形格网单元表示。只要在该1度×1度格网单元内的任意区域发生过捕捞活动，该单元即被纳入数据集。请注意，本数据集纳入的格网单元可能会部分覆盖陆地。为符合澳大利亚渔业管理局（AFMA）的信息披露政策，AFMA提供的原始数据已经过过滤，移除了分析区域内作业船只少于5艘的捕捞活动数据（政策链接：https://www.afma.gov.au/about/fisheries-management-policies/information-disclosure-fisheries-management-paper）。
