Metadata: 2015-2016 Acoustic Telemetry data for European eels (Anguilla anguilla) in Hanningfield reservoir, Essex, UK
Abstract:
Data from the tagging and tracking of European eels (Anguilla anguilla) in Hanningfield reservoir in 2015 and 2016. Acoustic tagging was undertaken on 36 eels between September and December 2015, then again on 68 eels between June and August 2016. In each year, the fine-scale movements of eels in the reservoir were tracked for a 6-month period. Various biometric recordings were taken whilst the eels were anaesthetised, such as total length and weight, pectoral fin size and length, vertical and horizonal eye measures, and lipid percentage.
Data holder:
Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory (CEFAS)

| Internal code | Internally assigned metadata identifier | 9131 |
| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | 2015-2016 Acoustic Telemetry data for European eels (Anguilla anguilla) in Hanningfield reservoir, Essex, UK |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | CEFAS119ce486-0083-46da-bc44-50068c170c34 |
| Resource Identifier | This is the code assigned by the data owner. | CEFAS21846 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2015-09-11 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2016-12-31 |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The data were collected over the course of several tagging surveys between 2015 and 2016. Acoustic telemetry data on the eel positions was collected using an array of 31 receivers (Vemco VR2W V5–180 kHz), which were deployed in the reservoir between 29 July 2015 and 14 December 2016. Lipid level was measured with the calibrated Distell fatmeter (model-FM 692) and used as an indicator of eel fitness. |
