fishermen hoped to maintain liaison with the Fisheries Experiment 

 Station in the future, supplying data and supporting basic investi- 

 gations. Notes We commonly divide the tunas into the ^ following 

 varieties — black tuna, big-eyed tuna, yellowfin tuna, spearfishes, 

 and albacore. Some brief comment will be made on each of theses 



(1) Black tuna ( kuromaguro , maguro, kuroshib ij young fish 

 are called kurome'ji c ) Large fish weigh Trom UOO to 

 500 pounds, rarely to 575 or 650 poundso Ihey occur 

 over a broad area from Hokkaido to the Kuriles, and 

 from the South Seas to the Japan Seao In the North 

 Pacific, they are taken from early summer through to 

 winter, while in the Japan Sea area, the summer and 

 winter are the best fishing seasons, 



(2) Big-eyed tuna ( mebachi , bachi ; young fish are called 

 bachi meji or daruma o ) Large fish attain a weight of 

 250 pounds o This fish is taken to some extent every- 

 where in the Pacific south of about 36° to 37°No lati- 

 tude but it is not very numerous in the north„ 



(3) Yellowfin (kihadaj young are called kimeji o ) Ihis 

 species wei^s from kO - 50 pounds to lif5 - I30 pounds. 

 Its distribution is about the same as that of the big- 

 eyed tuna, being numerous in the South Pacific and the 

 Indian Oceano This is the most important species in 

 the tuna fishery of the South Seas, 



CU) Spearfishes ( kajiki ). There are a number of varieties 

 such as the striped marlin, broadbill, sailfish, black 

 marlin, and white marline Except for the broadbill, 

 these fish are taken in greatest numbers in the warm 

 seas of the South, The broadbill has in recent years 

 become an important object of fishing in this prefecture, 



(5) Albacore ( binnaga , tonbo , bincho, ) Ihose taken are for 

 the most part from 15 to 25 pounds in weight, but small 

 fish of 6 to 7 pounds and large ones of about 100 pounds 

 are also seeno This species is ordinarily taken from the 

 waters east of Kinkazan to about ii5°N<. latitude from 

 November to July of the following year, (Not many are 

 taken in April or from August to Octobero)
