We should not be publishing fishing events for vessels that we do not believe are fishing vessels. Consider filtering with something like:

WITH 
  fishing as (
  SELECT
    DISTINCT CAST(mmsi as STRING) as ssvid
  FROM
    `gfw_research.vessel_info_allyears_20181002`
  WHERE
    on_fishing_list_best
    AND is_active
    AND (spoofing_days < 5
      OR spoofing_days IS NULL)
    AND (spoofing_factor < 1.05
      OR spoofing_factor IS NULL)
)
SELECT * FROM messages JOIN fishing USING (ssvid)
