 leading to assess the escapement of red salmon 

 from the trends of daily catches at the fyke 

 traps. For example, if the trends of the catches 

 in 1957 and 1958 during the periods July 15 to 

 July 25 are compared, one would assume that 

 the escapement was much less in 1958. 

 Actually, the total trap catches for the 2 years 



were nearly the same, the 1958 migration 

 extending over a much longer time.

The results of fishing four traps in various
