了解全球渔业格局对渔业管理有很大帮助。通过将统一的未绘制地图的数据源与卫星跟踪数据、区域金枪鱼管理组织、捕捞分类群的范围、船队的进入和相关渔具的物流相结合，说明了近世纪半（1869-2015）海洋渔业的扩张和集约化。对工业、非工业报告、非法/未报告和抛弃物的估计显示了国家主导地位、渔获物组成和渔具使用的变化。按年份、捕鱼国、分类群和渔具分列的工业和非工业海洋捕捞渔获量，按30分钟空间单元分列，包括报告的、非法、未报告和无管制的捕捞和丢弃物。结果显示，底拖网的数量有历史性的增加，而围网的上岸量相应减少。尽管种类繁多，但全球上岸量目前以底层和小型中上层鱼种为主。
Understanding global fisheries patterns contributes significantly to their management. By combining harmonized unmapped data sources with maps from satellite tracking data, regional tuna management organisations, the ranges of fished taxa, the access of fleets and the logistics of associated fishing gears the expansion and intensification of marine fisheries for nearly a century and half (1869-2015) is illustrated. Estimates of industrial, non-industrial reported, illegal/unreported (IUU) and discards reveal changes in country dominance, catch composition and fishing gear use. Catch of industrial and non-industrial marine fishing by year, fishing country, taxa and gear by 30-min spatial cell broken to reported, IUU and discards is available. Results show a historical increase in bottom trawl with corresponding reduction in the landings from seines. Though diverse, global landings are now dominated by demersal and small pelagic species.
