BULLETIN OF THE BUREAU OF FISHERIES 



RETURNS FROM EXPERIMENTS NEAR NELSON COVE, CLARENCE 



STRAIT 



Tagging was done here on two days — July 6 and 7 ; 659 fish were tagged, of 

 which 68 were reds, 116 cohos, 288 pinks, and 187 chums. There were no experi- 

 ments in previous years that can be compared directly with these, but supplementary 

 experiments are planned for future years. 



RED SALMON 



Sixty-eight were tagged but only 11 were recaptured and reported. The data 

 for these are given in Table 6 and show a general distribution toward Ernest Sound 

 and Revillagigedo Channel. One was taken near Cape Fox and another in British 

 Columbia. The data are too few to be thoroughly reliable; but, so far as they 

 go, they do not indicate that either the Boca de Quadra fish or the fish from the 

 streams of British Columbia are found in any great numbers along the western coast 

 of Gravina Island in the region of Nelson Cove.

COHOS 



The data for the cohos tagged near Nelson Cove are given in Table 7 and Figure 5. 

 These show, as in the case of the red salmon, a distribution through Clarence Strait, 

 Behm Canal, and Revillagigedo Channel, but indicate a distinctly heavier migration 

 to the streams of northern British Columbia. Of 24 recaptured fish, 7 (30 per cent) 

 were taken in Canadian waters, including both the Nass and the Skeena Rivers. 

 This result is in accord with those from the experiments conducted in the region of 

 Cape Fox and indicates a distinctly wider range of the cohos than of the other species 

 tagged.
