tion from the fishery, even at a catch level of 

 one million tons, would still produce only a 

 small fraction of total American fish meal 

 consumption. Market price can thus be taken 

 as given to the California meal producer, and 

 the estimated net economic rent available under 

 various assumptions as to management regime 

 can then be calculated on the basis of alternative 

 forecasts of the time-path offish meal prices. 



THE PACIFIC SALMON FISHERY 



In Appendix I the general format of a pre- 

 liminai-y program for modeling the Pacific 

 salmon fishery is presented. The objectives in 

 modeling this extraordinarily complex opera- 

 tion are partly methodological and partly aimed 

 at answering specific management problems of 

 real significance. The complications are ap- 



parent. Five separate species of salmon are 

 involved, and since each river usually contains 

 more than one species (and separate races of 

 the same species), the number of "management 

 units" which should, in theory, receive separate 

 treatment in modeling the stock sector is 

 probably from eight to ten thousaiidl 



"The salmon fishery" is actually a large num- 

 ber of geographically separate operations, linked 

 in varying degrees by the mobility of the gear 

 involved. Several types of gear are used, and the 

 relative importance of each type varies from 

 area to area. Finally, salmon deteriorate very 

 rapidly unless processed soon after being cap- 

 tured, which creates a large number of primary 

 markets in which processors generate several 

 different end products from each of the types 

 of salmon purchased. 



Even with the prodigious capacity of the
