The resiilts of racial studies provide two important 

 answers related to problems of the Protocol. First, infor- 

 mation on the extent of mixing of the salmon on the high seas 

 is further strengthened. The east-west extent of the mixing 

 area is shown in figure 4, North American red salmon, the 

 species of greatest concern, have been recognized by the 

 Commission to predominate in catches as far west as 175° 

 E; these red salmon originated in the Bristol Bay region. 



Figure 4.--East-west extent of high seas mixing between American and Asian salmon. 

 The area observed was near the Aleutians. The bars indicate for each species the range 

 of latitude over which American and Asian fish are commonly found in the same waters. 



But the most important problem at this time is raised by 

 the information on proportions of Bristol Bay red Seilmon 

 found in various areas of the high seas (fig. 1), Even though 

 the data presented here are only of the most general nature, 

 the chart does show the extent of the Bristol Bay red salmion 

 runs which migrate beyond the provisional line and are 

 subject to capture by the Japanese fishery. This is the 

 problem of the Protocol now before the Commission.
