  trips,
  census,
  gear_groups,
  vessel_groups,
  min_samples = 5,
  min_district_trips = 10
)

Arguments

trips

Output of fao_trips() for one country.

census

The Airtable frame_units table: boats per district (gaul_2_code) by boat type (vessel_standard_name) and main gear (gear_standard_name), either left empty where the country's census does not count it.

gear_groups

The Airtable gears table's standard_name and fao_category. A gear without a category stays its own unit.

vessel_groups

The country's rows of the Airtable vessels table: standard_name and vessel_group. A boat type without a group stays its own.

min_samples

Trips (or weekly answers) a district, unit and month needs to stand on its own; below it, it borrows as described in raise_catch_fao().

min_district_trips

Surveyed trips a district and month needs to be raised at all.

Value

One row per district, fishing unit and month that has trips and a census count; on_foot marks the units of fishers without a boat.
