Export WorldFish Survey Data

Processes validated survey data from WorldFish sources, filtering out flagged submissions and generating two key datasets:

1. Indicators dataset with aggregated catch metrics

2. Taxa dataset with species-specific catch information

Usage

export_wf_data(log_threshold = logger::DEBUG)

Arguments

log_threshold

The logging level threshold for the logger package (e.g., DEBUG, INFO) See logger::log_levels for available options.

Value

Two data frames (invisible):

• indicators_df: Aggregated catch metrics by submission

• taxa_df: Species-specific catch information

Details

The function performs the following operations:

• Retrieves validated WF survey data

• Pulls submission flags from MongoDB

• Filters out submissions with alert flags

• For the indicators dataset:

  • Aggregates catch data by submission

  • Calculates price per kg, CPUE, and RPUE metrics

• For the taxa dataset:

  • Preserves taxonomic information

  • Calculates catch metrics by species

The metrics calculated include:

• Total catch weight per submission

• Price per kg of catch

• CPUE (Catch Per Unit Effort)

• RPUE (Revenue Per Unit Effort)

if (FALSE) { # \dontrun{
# Export WF data with default debug logging

# Export with info-level logging only
export_wf_data(logger::INFO)
} # }
