    "description": "Data from the tagging and tracking of European eels (*Anguilla anguilla*) in \r\nHanningfield reservoir in 2015 and 2016. Acoustic tagging was undertaken on 36 \r\neels between September and December 2015, then again on 68 eels between June \r\nand August 2016. In each year, the fine-scale movements of eels in the \r\nreservoir were tracked for a 6-month period. Various biometric recordings were \r\ntaken whilst the eels were anaesthetised, such as total length and weight, \r\npectoral fin size and length, vertical and horizonal eye measures, and lipid \r\npercentage.",
