10. Summary tabic of the results of operations (_ Omitted from the transla- 

 tion._y 



IL. Opinions concernin,L^ vessels, gear, methods, grounds, and seasons 



The results of two years of investigations indicate th-^t fishing boats 

 which take part in the summer albacore fishery must have rreat cruising' 

 range. They must be able to opcr'^.te at least 4-} 000 miles off shore and to 

 remain on the grounds for 15 days or more. For these reasons vessels ^f 

 the 250-ton class or larger would bo ideal. 



It is believed that with large vessels there would be no limit to the 

 fishing season, however, for vessels of 200 tons or smaller it is believed 

 that the period from the latter part of /iur;u3+. to the latter part of October 

 will be the m.ost suitable fishin"; season since it appears that during' this 

 period the schr^ols tend to move into the western part of the North Pacific, 



The results of investi;:;'itions in Area III indicate that since the 

 albacore are generally small, better cntcli rates are had using small hooks. 

 Hooks 2 sun 8 bu / 3,36 inches^/ or less in length seemed to be suitable, 

 however, it has not been possible on the basis of the data from two years' 

 investigations to determine whether or not many sm.all albacore migrate into 

 Area III. Furthermore it app'^aro that more study is required with regard 

 to the size and length of trunk lines and branch linos, the length of 

 float lines, and so forth. 



12. Other items considered necessary 



Since the distribution --f wat'"-r tem.perature s in the areas covered by 

 the exploration of albacore fishing grounds is cxtrrmely complex, it appears 

 that one help toward the attainment of the objectives of these surveys would 

 be for the fisheries guide vessels to maintain a close radio liaison v.ath 

 each other in order to transmit information concerning the distribution of 

 temperatures at the 50-metcr level and other essential item.s which night 

 serve as data for the selection of fishing grounds.
