title: Conservation translocation of Atlantic wolffish (Anarhichas lupus) to a depleted Arctic fjord ecosystem

description: Large predators can have important functional roles in coastal ecosystems.
 In cases where such species are locally depleted or extirpated, a
 proactive restoration strategy may include conservation translocation.
 This study reports on such translocations of Atlantic wolffish (Anarhichas
 lupus) to fjord habitats in northern Norway where the species is currently
 severely depleted. A total of 20 pioneer individuals measuring 42 – 80 cm
 in length were captured in outer coastal habitats and subsequently tagged,
 released, and tracked within a fjord using acoustic telemetry. A first
 group of seven individuals were monitored for 14 months during 2017 and
 2018 while a second group of 13 individuals were monitored for four months
 during 2019. Up to 40% of translocated wolffish remained inside their new
 fjord environment until the study was terminated, while the remaining 60%
 likely dispersed. Weekly home range size decreased substantially with time
 for larger fish while this trend was weaker for smaller fish. Our study
 implies that there is reason for cautions optimism regarding the
 implementation of conservation translocation of wolffish in coastal
 ecosystems.
description: Atlantic wolffish were captured in the wild, tagged with acoustic
 transmitters, and translocated to to the inner part of a fjord where their
 movements and fate wre monitored within a fixed array of acoustic
 telemetry receivers. Detection data were downloaded at the end of the
 study, and thereafter processed and analysed using several scripts witin
 the R software.

 depleted Arctic fjord ecosystem
 [https://doi.org/10.5061/dryad.sqv9s4ncj](https://doi.org/10.5061/dryad.sqv9s4ncj) ## Description of the data and file structure Atlantic wolffish were captured in outer coastal habitats, near the Barents Sea, and transported to a field stations for tagging. Each individual was equipped with an acoustic telemetry transmitter with a depth sensor. After tagging, the fish were released in the inner part of a fjord monitored with a fixed array of telemetry receivers (Vemco VR2W's). Detection data was downloaded from the receivers at the end of the study period and based on these, we quantified individual fish movements and fate (residency vs. dispersal from the fjord). Data processing and analyses were conducted using several R-scripts that are available here along with the data files. I all data files, an empty cell means that this information has not been collected (missing data).  ### Files and variables #### File: Depth\_1804.csv **Description:** Telemetry depth detections from wolffish ID 1804.

Code/software All data processing, filtering, analyses and preparation of figures was done using the R-software (Version 2024.04.2+764) and the tidyverse package. We used several self-developed scripts to filter and analyze the data, and to prepare figures. The scripts are numbered from 1-8 and each of them has a description of what they do; top rows. These descriptions are also provided below: 1.WolfDepth.R:  \# This script filters individual depth detections, excluding duplicates where one transmission has been detected and stored by several receivers. The script stores the filtered data in a new file.  2.WolfFate.R: \# This script estimates individual fate (dispersed, dead or survived) from raw detection data. 3.WolfPAV.R: \# This script does individual position averaging using the PAV method developed by Simpfendorfer et al. 2002 (CJFAS paper). 4.WolfMetrics.R: \# This script does individual behavioural metrics for export to statistical analyses. 4b.WolfHR.R: \# This script does individual home ranges using the PAV (position averaging) files. 4c.WolfHRplot.R: \# This script ployts the individual home ranges using the PAV (position averaging) files. 5.WolfAnalyses.R: \# This script does plotting and statistical analyses of the wolffish telemetry data. 6.WolfMap.R: \# This script draws a map and positions. 7.PAVtoUTM.R: \# This script estimates individual home range sizes (hectares) using the PAV files. 8.MapPAVs.R: \# This script draws the average positions (PAVs) for each tagged fish on a map.
