 Each day about 9 miles of gill net is set and lifted by each 

 Japanese high-seas gill net vessel. 



Most of the salmon caught by Japanese on the high 

 seas are of Asian origin; some salmon of North American 

 origin are also taken each year. North American fish of 

 Bristol Baj' origin are particularly vulnerable to capture 

 by the Japanese on the high seas. These fish migrate to 

 the west of the provisional line and are found 

 intermingled with salmon of Asian origin. These are both

taken and immature fish destined to return in following 

 years. The estimated numbers of Bristol Bay sockeye 

 salmon taken by the Japanese have varied from a low of 

 about 400,000 of the 1952 and 1953 returns to a high 

 of 9,700,000 of the 1957 return. The smallest estimated 

 portion of the total Bristol Bay return of sockeye 

 salmon taken by the Japanese was 2.3 percent of the 

 1952 return, and the largest portion was 44.7 percent of 

 the 1957 return (table 6). 



Accordmg to Neo (1963), in order to coordinate the 

 activities of the salmon fleets and to prevent loss of 

 efficiency through gear interference, the Fishery Agency 

 has divided the high seas north of lat. 40 N. into 196 

 blocks or squares. These blocks measure about 50 miles 

 (east-west) by 60 miles (north-south). Each fleet.
