APPENDIX I: PACIFIC SALMON SIMULATION MODEL COMPONENT 



The proposed simulation model will treat the five species of Pacific salmon in the North American 

 fisheries as five separate stocks : 



Si Chinook 



S) Chum 



S.s Pink 



54 Sockeye 



55 Coho 



The location sector in the model will be based on the areas for which statistical information is 

 available in published data sources: 



Li Western Alaska 



L2 Central Alaska 



L:i Southeastern Alaska 



L4 Northern B.C. 



L.T Southern B.C./Fraser River 



Lk Puget Sound 



L7 Washington Coast 



Lk Columbia River 



Lh Oregon Coast 



Lio California 



Stock/location interaction will be as follows:

and these interactions reflect the distribution of species in the actual fishery. Data will be collected 

 to permit segregation of stocks into age groups, with age specific weights and spawner-return curves 

 (Ricker, 1958) developed for each stock/location. In effect, this scheme results in a total of 45 separate 

 stocks, since each species in each location will be treated separately with respect to spawner-return 

 characteristics. 



Regulators will be based on locations, with one regulator in each location. 



The principal types of fishing gear in the Pacific salmon fisheries are as follows: 



Gill nets, drift 

 Gill nets, anchor
