2. To raise the productivity of tho offshor.; fir"-^-'*-' "^ ■i''.-, 



a. Fishing gear 



It appears that tho catch in generally propcrtionod to tho nuj.x.;!- .. 

 baskets of gear fished. In ray view at the very v/orst ? catch of a value 

 of ¥100 can be expected fror. 100 baskets of lino. Accordingly in the 

 future I would like to see the efficiency of lar;;'c fishinr vessels raisad 

 to the point vjhere they could fish 500 baskets in 21*. hours. This r-oai:s 

 that the gear and other equipnent nust be strcnffthcned and nv..w r.ethods of 

 handling it must be devised. In order to strengthen the gear for use in 

 single vessel operations in the future stainless r.ctal wire should be 

 incorporated in the lines. The losses of lino each' secaon by fishing 

 vessels at present are very great and arc ostinated to aaount to 500-1,000 

 yen per boat. 



The construction of the longlines in general use today is so cxtrenely 

 primitive and results in such inefficiency, inconvenience, and dajipcr i.rx 

 setting and hauling the lines that it v;ill hardly bt.ar exa ir.inati on. 



The prevention of tangling of tho trunk lines and branch lines or 

 float lines, the sinplification of tho separation and ,joinin£; of ti.e lines, 

 and the mechanization of line handling should all be studied. It would be 

 desirable to have numbers starpod on the hooks to facilitate investigations, 

 and the branch lines could well be made very short. 



b. Auxiliary fishing gear 



Line-hauler rollers, line baskets, line-ccilors, line-throwers, 

 and flags have become expensive. There is a need for irprovenents in 

 wooden floats and the easily broken ,;lass floats. 



c. Fishing methods 



In order to effect the greatest posaablo increeso in the number of 

 baskets of gear the gear m.ust be improved and time-savin?; methods r-ust be 

 devised. 



1. Specialization 



2. Increased efficiency 



3. Division of labor 



i^. Combined use of long branches 



That is to say, under 1, two boats should operate, ^s a team, one 

 specializing in laying the line and tho other l-n hauling it. Topic 2 

 means that in order to raise the effective fishing tine of the lines they 

 must be in the water at all times and that it is not proper, as at present, 

 to set and haul the lines in such a way that th.ere is a period v/hcn they are 

 not in the water. For day and night fishing the personnel rust be divided 

 into watches. '7ith regard to 3j on the present fishing boats each person 

 does not have well-defined duties. There should be a division of tasks so
