Historical salmon (Salmo salar) catches in the Elbe catchment since the 16th century according to historical sources and recent catch data

Until the middle of the 20th century, the Atlantic salmon (Salmo salar) was an important migratory fish species in the Elbe River. Its decline and disappearance from the river and its tributaries during the last century can be seen as an indication of changes in the river habitat. Here we provide a georeferenced database on historical and recent Atlantic salmon catches in the Elbe River and its tributaries created by a literature review. The database consists of documented catches from secondary sources between 1432 and 2021 and also includes information about spatio-temporal inaccuracies.

20世纪中期以前，大西洋鲑（Salmo salar）是易北河的重要洄游鱼类物种。上个世纪间，该物种在易北河及其支流中的种群衰减与消失，可作为河流生境变化的重要指征。本研究通过文献综述，构建了易北河及其支流范围内历史与近期大西洋鲑捕捞量的地理参考数据库（georeferenced database）。该数据库收录了1432年至2021年间来自二手文献的已记录捕捞数据，同时包含了相关时空信息的误差说明。
