In HaikunXu/BSE: IATTC's BSE code
knitr::opts_chunk$set(results = FALSE)
This example code demonstrates how to extract the purse-seine catch and length composition d3ta for the stock assessment of bigeye tuna in the eastern Pacific Ocean. Data are extracted for bigeye between 2000 and 2023 based on the R package BSE (version r packageVersion("BSE")). The package can be installed using devtools::install_github('HaikunXu/BSE',ref='main').
- Step 1: set up some directories and parameters for the extraction
# devtools::install_github('HaikunXu/BSE',ref='main')
library(BSE)
# Load the base files (please ask Haikun to get those data)
raw_data_dir <- "D:/OneDrive - IATTC/IATTC/2024/SAC15/PS Database/"
# the directory where output will be saved
save_dir <- "D:/OneDrive - IATTC/IATTC/2024/SAC15/PS Database/BSE/"
yr.start <- 2000
yr.end <- 2023
Species <- "BET"
grow.increments <- grow.increments.betyftskj # the growth increment matrix
# area substitution matrix
area.substitution.mat.OBJ <- matrix(c(1,2,3,4,5,
2,1,3,4,5,
3,4,2,5,1,
4,3,5,2,1,
5,3,4,2,1),
ncol = 5, byrow = TRUE)
area.substitution.mat.NOA <- matrix(c(1,2,
2,1),
ncol = 2, byrow = TRUE)
area.substitution.mat.DEL <- matrix(c(1,2,
2,1),
ncol = 2, byrow = TRUE)
#fishery substitute matrix
my.FOmatrix <- matrix(paste0("FO.A", area.substitution.mat.OBJ),ncol=ncol(area.substitution.mat.OBJ))
my.UNmatrix <- matrix(paste0("UN.A", area.substitution.mat.NOA),ncol=ncol(area.substitution.mat.NOA))
my.DPmatrix <- matrix(paste0("DP.A", area.substitution.mat.DEL),ncol=ncol(area.substitution.mat.DEL))
- Step 2: lightly process the raw data so that they can be easily used in rest of steps
# Get the total unloads for the PS fleet
total.unlds <- read.unloads.f(raw_data_dir,"Unloading2000-2023.txt",yr.start,yr.end)
# Get the CAE+IDM data
cae <- read.cae.f(raw_data_dir,"CAE-LatLon2000-2023.txt",yr.start,yr.end)
# Get the length-frequency data (length in millimeters)
lfmm <- read.lfmmdata.f(raw_data_dir,"LengthMM2000-2023.txt")
# Get the grouped length-frequency output
lfgrpd <- read.lengthfreq.f(raw_data_dir,"LengthFreq2000-2023.txt")
- Step 3: compile the OBJ catch and composition data for BET
PS <- "OBJ"
area.substitution.mat <- area.substitution.mat.OBJ

Check the strata definition for OBJ in both cae and lf data sets to make sure that they are correct
check.strat.flg.f(cae$latc5,cae$lonc5,cae.stratflg)
check.strat.flg.f(lfgrpd$lat.5deg,lfgrpd$lon.5deg,lfgrpd.stratflg)
Loop through every year between yr.start and yr.end to get catch and composition data for BET in the OBJ fishery

}
# save middle-step data as a record
save(list=objects(pat="fishery.estimates"),file=paste0(save_dir,"BET_",PS,"_2000-2023.RData"))
Get final OBJ catch and comp output for the stock assessment

BET.OBJ.Comp.20002023<-compile.sizecomps.output.f(yr.start,yr.end,PS=PS,Species=Species)
- Step 4: compile the NOA catch and composition data for BET
PS <- "NOA"
area.substitution.mat <- area.substitution.mat.NOA
cae.stratflg <- create.strat.flg.f(cae$latc5,cae$lonc5,is.lwrght=F,cae$month,cae$setype,cae$class,PS=PS,Species=Species)

}
# save middle-step data as a record
save(list=objects(pat="fishery.estimates"),file=paste0(save_dir,"BET_",PS,"_2000-2023.RData"))
Get final NOA catch and comp output for the stock assessment
BET.NOA.Catch.20002023<-compile.catch.output.f(yr.start,yr.end,PS=PS,Species=Species,c("A1","A2")) # five NOA fisheries

# save middle-step data as a record
