Bait is essential for the skLpjack-yellowfin fishery 5 and the 

 albacore fishery also requires a large amount. For example, 82 per- 

 cent of the skip jack-yell owf in catch by the California fleet in 1950 

 was made v;ith bait (see table 63). It is conservatively estimated that 

 at least 70 percait of the entire tuna catch (all varieties of tuna) 

 made by the United States fleet in the eastern Pacific is taken with 

 bait, ~J This method of fishing for tuna is very efficient from the 

 standpoint of production per man day.

12/ Exact figures for the weight of other tunas, chiefly albacore, 

 taken with bait are not available. Taking the known catch of yellow- 

 fin and skipjack with bait (table 62) and assuming one-third of the 

 total catch of albacore (table 6I) was caught with bait, it is esti- 

 mated that at least 70 psrcen'':. of the total Pacific coast tuna catch 

 in 1950 (table 61) was made with bait.
