experiments, which showed considerable move- 

 ment out of the bay. The difference and expla- 

 nation lie in the fact that the Morzhovoi Bay ex- 

 periments were carried out relatively early in the 

 season when the salmon were still en route to 

 their parent streams. 



Conclusion 



This report is a partial analysis of the 

 1958 tag recovery data. Much detail has been 

 omitted, and much remains to be done before the 

 analysis is complete. The distribution of fishing 

 effort and the relative abundance of pink salmon 

 in the various sections of the Peninsula area have 

 not been considered in relation to the distribution 

 of tag recoveries. This must be done before the 

 true significance of these results can be stated. 

 Yet, incomplete as they are, the results of this 

 study have immediate value in the management of 

 the fishery. 



During June the fishery is supported by 

 runs of pink salmon bound for Bristol Bay and 

 areas along the northeast Bering Sea coast. 



There is little intermingling of fish that 

 appear in the fishery west of Bold Cape with those 

 that appear in the waters of the Shumagin Islands 

 and the mainland coast north and east of the Shuma- 

 gins. Pink salmon bound for mainland bays north 

 and east of the Shumagin Islands, particularly 

 that reach of coast from Balboa Bay through Stepo- 

 vak Bay, pass through the Shumagins . The fish- 

 ery west of the Shumagins does not appear to 

 draw on these runs. 



For practical purposes, the western limit 

 of migration of fish passing through the Shumagins 

 after July 1 should be considered as Pavlof Bay. 

 The data indicate that the area comprised of Ika- 

 tan Bay, Morzhovoi Bay , and Cold Bay should be 

 considered as a unit. 



Once pink salmon enter bays of the area 

 they show little tendency to leave, especially after 

 mid-July. Further, populations within a given 

 bay after this time tend to be distinct; tagging 

 within bays showed very few individuals traveling 

 to either adjacent or distant waters. Under these 

 circumstances it can readily be seen that heavy 

 fishing could reduce the runs to dangerously low 

 levels .
