appeared most suitable, '^ile this mr.y have been due in pnrt to the rich 

 concentr^ition of plankton, in nost cases it was probably that the fish arc 

 most stimulated to bite by a moving bait than by a still one. 



6. Methods of preserving bait and relationship of freshness to bait-takiuv, 



In these operations the baits used were frozen squid (frozen mackcTel) 

 and salted sardines. The frozen baits were preserved by opcratinr_ the re- 

 frigeration machinery safficiciitly to keep them from thrj.ln;;^. The salted 

 sardines were kept in a separate hold. On xhe third crii.isG 7- momne frozen 

 squid were used together v;ith salted sardines on the small hooks as bait 

 for albacore, but their relative effGct:".vencss was not clear. As for the 

 relationship bct'TCen freshness and bait- taking, in general the fresher the 

 bait the better the catch ratios.

7. Sizes of the largest and the snallest albacore- taken, and the type of 

 school and the average size of fish taken in tlie bigt.est single catch 



The largest fish taken ivas 1 m.etcr long and -.eighcd 27.2 ka. The 

 smallest was UU en long and weighed 2.^^.6 kg. The bi^s-cst single catch uas 

 165 fish. T-c largest vir.s 1 meter long and weighed 27.2 \^^i the smallast 

 was U1 cm long and 77ei*/hed 2.86 kr:; the average was 73.2 cm long and v;eighcd 

 8.11 kg. 



8. Method of handling an.i preserving the catch 



Large fish such as big-eyed tuna and r.arlin were opened up as soon as 

 they were caught and the gills and viscera v;ere removed. Albacore ".nd other 

 small fish were stowed in the round. The fish were all thoroughly i-x.shcd 

 with sea ViTatcr, the largo ones were iTrapped in cloth, the albacore were 

 TvTapped in waxed paper, after \'7hich they were laid on the racks in the fish- 

 holds and covered with enough crushed ice so that the fish could not be seen. 

 The refrigerators vrere operated sufficiently to keep the ice from melting. 



9t Place and method of sale and proceeds 



The catch was sold at Hisaki in Kr.na.-avra Prefecture and at K?maishi 

 in Iwate Prefecture. The prices and the value of the landings are given in 

 the summary table of the results of operations.

11. Opinions concerning vessels, gear, m.othods, groimds, and se'^son 



(a) With regard to the fishing vessel, since it should be economical and 

 efficient because of the larj^e number o^ d'-ys reqiiired for goin^ to and from 

 the fishing grounds, the best type should be a boat of tho lOO-ton class 

 with capacious fishholds and thoroughly adequate refrigeration facilities. 

 Large-scale operations of the mothcrship type should also be suitable.
