  release_seasons = NULL, recapture_season = NULL,
  within_season_recaps = FALSE)

Arguments

release_data	a single column data frame with the CCAMLR fishing season of individual fish release events
recapture_data	a two column data frame with the CCAMLR fishing season of release in the first column with the matched CCAMLR fishing season of recapture in the second column for each individual tagged fish.
release_seasons	vector of seasons of interest where the default = NULL uses release_data seasons included in release_data dataframe
recapture_season	a single season that should match the catch season if applying a tag based estimate using the CCAMLR method where the default = NULL
within_season_recaps	is TRUE to include within season recaptures or FALSE to exclude them with default=FALSE
