the rate of travel of the salmon in the vicinity of the mouth of the 

 Fraser in the latter part of the season. 



Other years were not simulated in the detailed model described 

 in the preceding paragraph. The program (simulation model No. 1 ) 

 is available and any further simulation that may be of interest can be 

 carried out with ease. 



The same constants and general structure were built into the 

 second simulation model (simulation model No. 2) that was already 

 described in an earlier section. Simulation model No. 2 contains the 

 migratory routes shown in Figs. 10. 11, 12, and 13. Simulation of the 

 1959 run using simulation model No. 2 gave the results shown in 

 Table 2. It might be well to note that the computer catch is almost 

 perfectly adjusted between the two nations, whereas the actual catch 

 has a slight discrepancy. This was caused by the decision rule
