  2. Task I fleet characteristics - Number of fishing vessels by size classes, gear and flag.
  3. Task II catch and effort statistics - Catch and effort statistics by area, gear, flag, species and by month.
  4. Task II size data - Actual size frequencies of fish sampled by area, gear, flag, species and by month and by sex if possible.
  5. Catch-at-size data - Catch-at-size data for bluefin, albacore, yellowfin, bigeye and skipjack tunas and swordfish, by gear, sampling area and by month or quarters, and by sex and by 5x5 degree squares if possible. The ICCAT form 3-6 to show sampling coverage and data substitutions is also required.
