The Atlantic blue crab Callinectes sapidus is a portunid native to the western Atlantic, from New England to Uruguay. The species was introduced in Europe in 1901 where it has become invasive; additionally, a significant northward expansion has been emphasized in its native range. Here we present a harmonized global compilation of C. sapidus occurrences from native and non-native distribution ranges derived from online databases (GBIF, BISON, OBIS, and iNaturalist) as well as from unpublished and published sources. The dataset consists of 40,388 geo-referenced occurrences, 39,824 from native and 564 from non-native ranges, recorded in 53 countries. The implementation of quality controls imposed a severe reduction, in particular from online databases, of the records selected for inclusion in the dataset. In addition, a technical validation procedure was used to flag entries showing identical coordinates but different year of record, in-land occurrences and those located close to the coast. Similarly, a flagging system identified entries outside the known distribution of the species, or associated with unsuccessful introductions.
大西洋蓝蟹 Callinectes sapidus 是一种原产于西大西洋的蟹类，分布范围从新英格兰到乌拉圭。1901 年，该物种被引入欧洲，现已在那里泛滥成灾；此外，其分布范围在其原生范围内也向北显著扩张。在这里，我们从在线数据库（GBIF、BISON、OBIS 和 iNaturalist）以及未发表和已发表的来源中，提供了一个协调一致的大西洋蓝蟹原生和非原生分布范围的全球发生数据集。该数据集包含 40388 个地理参考发生点，其中 39824 个来自原生范围，564 个来自非原生范围，记录于 53 个国家。实施质量控制措施后，尤其是从在线数据库中，所选记录的数量严重减少，这些记录被包括在数据集中。此外，还采用了技术验证程序来标记显示相同坐标但记录年份不同、内陆发生和靠近海岸发生的条目。同样，一个标记系统也可以识别出已知物种分布范围之外或与不成功的引种相关的条目。
