Preprocess Catch Data for Both Survey Versions

preprocess_catch.Rd

Processes catch data from WorldFish surveys, handling both version 1 and version 2 survey structures. Automatically detects survey version and applies appropriate species field normalization and length group processing.

Usage

preprocess_catch(data = NULL, version = NULL)

Arguments

data

A data frame containing raw survey data with species groups

version

Character string specifying version ("v1", "v2", or "v3"). v2 and v3 share the same structure. If NULL, version will be auto-detected based on column patterns.

Value

A data frame with processed catch data including: submission_id, n_catch, count_method, catch_taxon, n_buckets, weight_bucket, individuals, length

Details

The function uses reshape_catch_data_v2() internally which automatically handles:

  • Version 1: Single species field, nested length groups

  • Version 2: Multiple species fields (species_TL, species_RF, etc.), separate length group structure for fish >100cm
