This repository contains the necessary code for reproducing results from the paper First-year distribution and movement rates of PIT-tagged North East Atlantic mackerel (Scomber Scombrus) varies with timing, location, and fish size at release during the spawning season.

Data

All use of the data should cite Slotte et. al.(2021).

The data used can be downloaded via API using functions from the fishvice/taggart package. The package can be installed by

devtools::install_github("fishvice/taggart", dependencies = FALSE)

Due to some no longer maintained dependent packages, we have also copied the necessary functions to download the data in the R/download_data_functions.R file.

The current data in Data/current.nc is average monthly surface current information (Northward and Eastward sea water velocity), from Copernicus Marine Service.
