The best catches i ^ I Ralik Chain have hitherto been made at 

 Ailinglapalap and Kili atolls, the waters near Kili appearing particularly 

 promising,, 



Methods 



Two fishing boats were used, with the Fisheries School training vessel 



Unyo Mara (V^4 tons, 330 rated horsepower) as tender. Eighteen baskets of 



Boshu type tuna long] in^ with six hooks to a basket were used. Bait was 

 frozen squid from Japan. 



General Description of the Gear 



Mainline 160 fathoms 



Float-lines 2 lines each 10 fathoms long 



Hooks 6 



Distance between float-lines and branch-lines 20 fathoms 



Branch-lines 



Long 132" fathoms (line 10 fathoms, cotton-wrapped hemp 3jj fathoms, 

 wire 1 fathom) 



Short 6 fathoms (line lg- fathoms, cotton-wrapped hemp 3g fathoms, 

 wire 1 fathom) 



Position of hooks in the wate^ (estimated) 

 Long branches 4.8 fathoms deep 

 Short branches 27 fathoms deep 



Progress 



Experimental fishing grounds were selected in comparatively calm areas 

 in the lee of the islands about 1 to 5 miles off the reef, taking into con- 

 sideration the movements of the schools, the difficulty or ease of navigation, 

 the number of trials which were to be made, and the safety of the fishing 

 vessels,, 



Bait 



The bait was refrigerated squid brought from Japan in the Unyo Maru's 

 cold storage,, Flying fish and all sorts of reef-fish are generally distributed 

 throughout thpse islands and can easily be taken for bait.
