The data sets were collected east of the Smøla archipelago in mid-Norway during 2017 - 2019. Details for each dataset are provided in the README file.
Data sets included:
1) Atlantic cod captures in traps
·      Individual tags used
·      Body size measurements of tagged cod
·      Information about sex, maturity stage, location and year of capture and release
2) Acoustic telemetry receiver array
·      Position and depth of deployed acoustic receivers
3) Individual cod detection files
·      Time stamp and location (receiver) for each detection
·      Sensor values (depth) for each detection
4) Cod movement data
·      Summary of network analyses conducted on individual cod
5) Map data
·      Coastline coordinates needed for mapping fish movements.
Missing values are denoted by empty cells.

Description of the data and file structure

1. File List:
 
A) tel_cod.csv
B) stationinfo.csv
C) Vemco User Environment (VUE) csv-files
D) transmitters.csv
E) cod_network.csv
F) mfishnet.csv
G) Movement network csv-files for fish displayed on map
H) smola_kyst.gpkg
 
2. Relationship between files\, if important:
 
A) The transmitter serial number is provided in both the tel_cod file and the cod_network file, for linking movement data to fish body size data and
B) the transmitters file contain both the unique tag IDs and serial numbers, needed for linking VUE detection file summaries to the tel_cod file
C) The receiver serial number is provided in both the stationinfo file and the VUE detection files, needed for quantifying fish movements (connectivity).
 
These relationships are also explained in the R-scripts, showing how files are combined.
 
3. Additional related data collected that was not included in the current data package: None
 
4. Are there multiple versions of the dataset? No
            A. If yes, name of file(s) that was updated: NA
                        i. Why was the file updated? NA
                        ii. When was the file updated? NA
