icesFO Functions to support the creation of ICES Fisheries Overviews, ....

icesFO is implemented as an R package and available on GitHub

Installation

icesFO can be installed from GitHub using the install_github command from the devtools package:

library(devtools)
install_github("ices-tools-prod/icesFO")

Usage

For a summary of the package:

library(icesFO)
?icesFO

Development

icesFO is developed openly on GitHub.

Feel free to open an issue there if you encounter problems or have suggestions for future versions.

The current development version can be installed using:

library(devtools)
install_github("ices-tools-prod/icesFO@devel")

Examples

Plot ecoregion map

In this example the map of the Greater North Sea ecoregion is plotted

see

?icesFO::plot_ecoregion_map

for more details

first download the ices area shape and the ecoregion shape. Both are converted to sf polygons for easy plotting

library(icesFO)

# download data
ices_areas_nrs <- load_areas("Greater North Sea")
ecoregion_nrs <- load_ecoregion("Greater North Sea")

then the plot can be made:

# plot
eco_map <- plot_ecoregion_map(ecoregion_nrs, ices_areas_nrs)

eco_map

Plot ICES official catch statistics

In this example, the plots for ICES official catch statistics for the Baltic Sea Ecoregion are made. First the data is downloaded and formated

see

?icesFO::plot_catch_trends

for more details

library(icesFO)

# download data
hist <- load_historical_catches()
official <- load_official_catches()
prelim <- load_preliminary_catches(2018)

# format / process
catch_dat <- format_catches(2018, "Baltic Sea Ecoregion", hist, official, prelim)

then the plot can be made:

# plot
p <- 
  plot_catch_trends(catch_dat, type = "COMMON_NAME", 
                    line_count = 5, plot_type = "line")
p

Plot surface swept area ratio plot

In this example the map of the average swept area ration for the Celtic Sea ecoregion is plotted

see

?icesFO::plot_sar_map

for more details

first download the ICES ecoregion shape. Both are converted to sf polygons for easy plotting

library(icesFO)

# download data
ecoregion_cs <- load_ecoregion("Celtic Seas")

Then dowload the SAR data using the icesVMS package.

NOTE: Only users with permission to access aggregated VMS data can use this service.

remotes::install_github("ices-tools-prod/icesVMS")
library(icesVMS)

# download data
sar <- icesVMS::get_sar_map("Celtic Seas")

# convert to sf
sar$wkt <- sf::st_as_sfc(sar$wkt)
sar <- sf::st_sf(sar, sf_column_name = "wkt", crs = 4326)

then the plot can be made:

# plot
sar_map <- plot_sar_map(sar, ecoregion_cs, what = "subsurface")
sar_map

Plot technical interactions

In this example, the plots of technical interactions between gears are shown

see

?icesFO::compute_technical_interactions

for more details

First we get the STECF landings data from the Baltic Sea Fishery overview repository.

library(icesTAF)

repoUrl <- 
  sprintf("https://raw.githubusercontent.com/ices-taf/%s/master/",
          "2019_BtS_FisheriesOverview")

STECF_landings <-
  read.taf(file.path(repoUrl, "bootstrap/initial/data/STECF_landings.csv"), 
    fileEncoding = "UTF-8-BOM", check.names = TRUE)

then the calculation and plot can be made:

technical_interacton <- 
  compute_technical_interactions(STECF_landings, catchCoverage = 0.99)

plot_technical_interactions(technical_interacton$recapLand)
