(b) The albcicore longlinos were made of No. 10 cotton line ^'dth 11 hooks 

 (3 large and 8 small) per basket. The. trunk line 3 -.verc formed of 12 15- 

 fathora lengths of 7- Tnoininc line giving a total length of 180 fathons. The 

 branch lines for the large hooks were 7 fathoins lon^ and were made of 9- 

 mcmme line. The branches for the small hooks r/cro of 6-mop.mc line and Viorc 

 2.5 fathoms long. The scki yr.ma for the lar^-e branches -tt.s 3 fathoms lon^ 

 and was made up of No. 23 vdrc '.capped with No. A cotton. The wire leaders 

 for the large hooks \i7cre of No, 28 wire and iverc l.S fathomb long. For the 

 small hooks the sekiyacia was made up of No. 29 vire served '.dth No. 2 cotton 

 and was 2 f ithoms long. T^irc leaders for the small hooks -Tcrc No. 29 ^r 



No. 30 vidrc 1,8 fathoms long. The hooks v;ere all tinned iron, the largo 

 ones U sun 2 bu /~5,04.. inchcs_7 and the small oms 2 sun 3 bu to 3 sun 2 bu 

 /~3.36 to 3.8^ inchc3_7 long. At the upper end of the seki>- amr of the large 

 hooks and at the upper end of the \d.rc leader of the sm-^ll hooks large and 

 small brass STdvcls respectively were attached. The float lines vrere 

 7-inomme flanila 15 fathoms long. The floats used i.7ere glass balls 10 Inches 

 in diameter. 



This a general description of the gear, but float lines of various 

 lengths Tvere used depending on the vnter temperature at the middle levels 

 and the depth at ;7hich the schools were swimming. On the first cruise 

 they were 15 fathoms long, 10 fathoms on the second cruise, and 5 fathom.s 

 on the third cruise. There is still room for further research on this 

 point. 



(c) Fishing methods, fishing grounds, fishing seasons 



For offshore albacorc fishing in the summer season longlincs should be 

 the principal method with pole and line and trolling as the auxiliary 

 methods. Area I is a suitable area and all research vessels should be 

 assigned to operate there. Viewing the total results of this investigation, 

 it appears that in summer the albacorc schools keep to zones of fairly 1ot7 

 temperature water. The first and second cruises were made somev/hat too far 

 south. During the latter part of the third cruise the catch ratios wsro 

 average and the fish --veighed as much as 3 kan 580 r ommc / 29.61 pounds_y. 

 There was, however, a tendency for the fish to m.ovo from north to south. 

 The results outlined above make it thought that the season extends almost 

 throughout the whole year.
