Abstract
This data repository includes the information utilized for visualization and analysis in the study titled "Evaluation of the Stocking Efficiency of a Rheophilic Cyprinid in a Large River System using Spatio-temporal PIT Tag Detections and Survival Analysis." The repository contains two datasets. The first dataset consists of data for 1,650 common nase (Chondrostroma nasus) and includes information such as PIT tag ID, length, weight, stocking location, and tagging time. The second dataset details the PIT tag detection history of the re-detected nase, which includes columns for tag IDs, detection time, and location. The detection dataset can be linked to the nase dataset via the PIT tag IDs.

Description of the data and file structure
The two data sets in this repository contains the data to reproduce the visualizations and analysis done in the study: "Evaluation of the Stocking Efficiency of a Rheophilic Cyprinid in a Large River System using Spatio-temporal PIT Tag Detections and Survival Analysis".
File: Detections_Nase.csv
Description contains the detection history of fish passing an antenna system in the River Inn in southern Germany
Variables:
site: Name of the site where the antenna is positioned the suffix up or down indicates the position inside a fish pass.
Tag_ID: ID of the recorded PIT tag
detected: datetime object given information on the time the PIT tag was recorded
reader: ID of the reader at the site
antenna: ID of the antenna at the site
signal: value of the antenna current
date: date of detection
time: time of detection
area: geographical area the fish was detected
antenna_position: position of antenna (can be Tributary, Up, or Down)
type: gives information on the habitat of the antenna site (can be Backwater, Tributary, or Fish Pass)
antenna_type: information on how the antenna is installed (can be pass-through or pass-over.
Release_ID: corresponds to the stocking group of the nase
File: Stocked_Nase.csv
Description contains information on the fish that were tagged with a PIT tag and stocked in the River Inn afterwards. The data sets contains the columns:
Variables:
Year: year the fish was tagged
Month: month the fish was tagged
Date: date the fish was tagged
Time: time the fish was tagged
Tag_ID: unique ID of the PIT tag used to mark the fish
Species: common name of the fish tagged
Weight_g: Weight of the fish measured to the closest gramm
Length_mm: Total length of the fish measured to the closest millimetre
Section: river section the fish was released
Site: stocking site the fish was realesed to
Type: Habitat type the fish was realeased to
Release_ID: ID to identify the stocking group
Both data sets can be connected via the Tag ID.
Code/software
The data sets are saved as a *csv file. The code to relicate the visualization and the analysis can be found on this git hub page https://github.com/JanDroll/Nase_Stocking.
