全球海洋商业性、小规模、非法及未报告渔获量数据库(1950–2014年)

来自多种公共来源的全球渔业登陆（渔获上岸）数据经过统一处理，并根据报告物种的分布及相关渔业船队活动，被映射到30分钟分辨率的空间网格单元中。数据还扩展包含了所使用的渔具类型，以及对非法、无管制和未报告渔获量（IUU）和海上丢弃量的估算。 这些结果以捕捞率的形式表示，并区分了小规模渔业与其他类型的渔业活动。该数据集涵盖了1950年至2014年（含）期间的资料。 通过空间映射的渔获数据，可以研究渔业对栖息地和动物群的影响、与海鸟和海洋哺乳动物食谱的重叠程度，以及与燃料使用和温室气体排放的关系。 这种高分辨率的空间数据还可按各国专属经济区（EEZ）进行聚合，用于分析海洋产品登陆对国家经济、粮食安全及其贸易伙伴经济的价值与影响。Global fisheries landings data from multiple public sources were uniformly processed and mapped to 30-minute resolution spatial grid cells based on the distributions of reported species and associated fishing fleet activities. The dataset also includes expanded information on the fishing gear types used, as well as estimates of illegal, unreported and unregulated (IUU) fishing catches and at-sea discards. These results are presented in the form of catch rates, with a clear distinction between small-scale fisheries and other types of fishing activities. The dataset covers all data from 1950 to 2014 (inclusive). The spatially mapped catch data enables research on the impacts of fisheries on habitats and fauna, the extent of dietary overlap with seabirds and marine mammals, as well as the correlations between fisheries and fuel use and greenhouse gas emissions. This high-resolution spatial data can also be aggregated based on countries' Exclusive Economic Zones (EEZs) to analyze the value and impact of marine product landings on national economies, food security, and the economies of their trading partners.
