(a) Poles — Ordinarj"- fishing poles can be used on the average for 

 about five monthSj and short poles become useless in one months Usually

 five or six of each, with the leaders attached, along with a considerable

 for use with artificial lures (where poles used for such fishing differ 

 from those used with bait) to the number of about two-thirds of the number 

 of crew members, m.th two or three hooks for each. 



(c) Trolling hooks (searching hocks / "saguri hari 7) — Each boat will 

 have prepared two sets of gear and five or six hooks, 



(d) Bait buckets — One for each fisherman with some extra ones.

 from the tanks, for placing it in the ready-box, and for distributing it 

 to the bait buckets.
