getters::get_pa

Ages are used from, "other" and "seine" - Either need to update figure caption to include the "other" category, or remove "other" gear type from dataframe used in proportion at age. 

Actually perhaps this is in plot_pa in herringutils::figures.R

df <- df %>%
    filter(year >= xlim[1], gear %in% c(
      en2fr("Other", translate = french),
      en2fr("RoeSN", translate = french)
    ))
