Check fish data from single point based methods
Claude Spencer & Brooke Gibbons

check-fish-point.RmdIntroduction
This script will take fish annotation data from single point based methods (e.g. stereo-BRUVs or stereo-BOSS), either exported from EventMeasure or “Generic” format (see format requirements here), and check for any errors in the annotation. The script will then format the annotation data into a tidy format.
You also need a formatted sample metadata file “*_Metadata.csv” (see format requirements here)
R set up
First you will need to load the necessary libraries. If you haven’t installed CheckEM before you will need to install CheckEM using the install_github function.
# install.packages('remotes')
library('remotes')
options(timeout=9999999)
# remotes::install_github("GlobalArchiveManual/CheckEM")
library(CheckEM)
library(tidyverse)
library(googlesheets4)
library(sf)
library(terra)
library(here)Next set the study name. This can be any name you like, all files saved using this script will be prefixed with this name. Avoid having a name that is too long. We recommend using a short project name that includes the method e.g. “2020_ningaloo_stereo-BRUVs”.
name <- "example-bruv-workflow"Metadata
Now we load and tidy the metadata. If you have already completed this step while checking your habitat data, then you can skip these next two chunks of code and simply read in the metadata (see below).
metadata <- read_metadata(here::here("r-workflows/data/raw/"), method = "BRUVs") %>% # Change here to "DOVs"
dplyr::select(campaignid, sample, status, longitude_dd, latitude_dd, date_time, location, site, depth_m, successful_count, successful_length, successful_habitat_forward, successful_habitat_backward) %>%

If you have already exported in the ‘check-habitat’ script then load the metadata. If you have just loaded and saved the metadata, then you can skip this chunk of code.
Marine Parks
Load marine park shape files, and extract fishing status (e.g. ‘Fished’ or ‘No-take’) for use in modelling. The data set used here is the 2022 Collaborative Australian Protected Areas Database, which you can download for free here.
You may change this shape file to any suitable data set that is available for your study area.
NOTE: You should only use this code if the Status column is not filled out
marine_parks <- st_read(here::here("r-workflows/data/spatial/shapefiles/Collaborative_Australian_Protected_Areas_Database_(CAPAD)_2022_-_Marine.shp")) %>%

There are two types of fish annotation data formats that you can check and format using this script: EventMeasure database outputs or Generic files.
For EventMeasure database outputs you will need to export the database outputs using the EventMeasure software and the .EMObs files. This will give you the ’_Points.txt’, ’_Lengths.txt’ and ’_3DPoints.txt’ files.
Generic data is a much simpler format and allows users who haven’t used EventMeasure to format QC their annotation data. You will need a _Count.csv file and a _Length.csv file.
For more information on the format of these files please see the CheckEM user guide
We recommend using the EventMeasure database outputs if they are available and up to date. There are more checks possible with EventMeasure data than Generic data. Note: If you have used EventMeasure software to annotate your samples BUT have made corrections on the exported data (e.g. in Excel), this corrected data is now the true copy of the data and you should import your data as Generic annotation files (e.g. count and length).
Load any EventMeasure Points.txt files
This section of code will read in any Points.txt files that you have saved in the directory you set. It will combine all of the files into one data-frame, and get the campaignid name from the name of the file. It is important that you consistently name your files with the same campaignid (look out for different separators e.g. ‘-’, ’_‘, or’.’)

Taxanomic advances means that species names are updated all the time, and analysts sometimes spell species names incorrectly. This check uses a data-frame saved inside the CheckEM package to identifies species names that have been updated or spelt incorrectly.
You can choose if you would like to find the synonyms using an Australia specific list (CheckEM::aus_synonyms) or a Global list (TO ADD).

Now that we have identified species names that have been updated or spelt wrong you need to decide if you want to change the names in your data or continue using the old names. If you want to update the names use the next two chunks. If you would like to retain the old names skip the next two chunks.
NOTE: this does not change your original annotation files, only the data you save at the end of the script.

In this check you use a list of species and their known geographical ranges to check your data against to identify any species that are outside of that range. There are two life history data sets to choose from to check any species that are outside of their known geographical range. They are the Australia and Global lists.
To use the Australia life history list use CheckEM::australia_life_history to use the Global life history list use CheckEM::global_life_history.
We run the check on both the count and length data, as sometimes a species will be in the count and not the length. All species identified in these checks are present in your chosen life-history list. Sometimes range data is limited, so it is possible that a species flagged in this check is actually present in that area. You need to critically think about the species flagged by this check.
Species out of range in the count data
Check for any species that are out of range in the count data.

This next check identifies any species that are not listed in your chosen life history list. It could be that you have misspelt the family/genus/species name, the species name is invalid, the name has been updated or that the species name should be included in the life history list but is missing. Again you will need to critically think about the species that are flagged to determine if this is an error or not.
To use the Australia life history list use CheckEM::australia_life_history to use the Global life history list use CheckEM::global_life_history.
NOTE. If you believe that a species flagged by this check should be included in the life history list please email brooke.gibbons@uwa.edu.au with the full species name and which list it should be added to (Global or Australia).
Species in the count data that are not listed
If you chose to update the names that have changed (synonyms) then this check won’t include the previously used names.

Length data is extremely valuable so it is important that fish are precisely and accurately measured. You can use this check to identify any measurements that are bigger than the maximum size listed on fishbase. However, we think it is important that you check any species that are nearing their maximum size (e.g 85% of maximum). We also think it is important that you check for any species that are very small. Fishbase does not list a minimum size, so we recommend checking the length measurements against 15% of the maximum size.
In the function below you can edit these cut offs (15% and 85%) as you see fit. If you believe the size limits for a particular species is incorrect you fill out the feedback form on the CheckEM web based app (see tab Edit maximum lengths) to supply a new maximum size limit.
