7. Sizes (weights, lengths) of the largest and smallest albacore taken, 

 and the number taken in the largest single catch 



Largest 21.38 kg 1.03 meters taken May 22 

 Smallest A. 31 O.ii? taken May 23 



The largest single catch was made on the first cruise on May 23 when 236 

 fish with an average weight of 9.8 kg were taken. 



8. Methods of handling and keeping the catch 



The fish were thoroughly cleaned and the dirt removed from the outside 

 of them. They were then wrapped in waxed paper and packed in crushed ice 

 in three tiers so that they were completely covered with ice. Boards 

 were placed between the layers of fish to keep then from pressing on each 

 other and to give the ice a chance to work most effectively. 



9. Place, proceeds, and manner of sale 



The catch was sold at Misaki in Kanagawn Prefecture at auction by 

 written bid. The total value of the landings from all four cruises was 

 ¥ 10,010.39 and the total proceeds realized were ¥ 9,309.69.

11. Opinions concerning vessels, gear, methods, grounds, and seasons 



a. Fishing vessels 



Since the vessels are to operate in distant waters, the first principle 

 is that they should be strong. The period covered by this survey v/as a 

 comparatively calm season and there was little fear of clanger from bad 

 weather, but the fishing grounds are about 1,600 miles from the base, 

 and it requires over 16 days for the trip out and back so thr boats must 

 be correspondingly equipped with cargo capacity and facilities for the 

 preservation of the catch so as to be able to increase the number of drys 

 spent in operations on the fishing grounds, /ccnrdin^ ly the cpacity of 

 the fuel tanks must be increased and the insulation of the fishholds must 

 be perfected. In view of these facts, the PiJusashi Maru .vrs provided with 

 as much additional fuel capacity as her hull could stand ?.lthout being 

 weakened and the icehold which had the poorest insulation was repaired. 

 It is thought that ideally the vessel should be of 180 tons with 360 

 horsepower and, since the operating period is during the sumwor, she should 

 be equipped with effective refrigeration machinery. 



b. Fishing gear and methods 



The main fishing gear is the longline, but pole-fishing and trolling 

 gear should be prepared for use, particularly as it sometimes happens 

 that dense schools swim near the surface and can be advantageously fished 

 with pole and line methods. On vessels like this one, however, there is 

 the drawback that because of the small capacity of the holds, vihen live
