TILLMAN and STADELMAN: SIMULATION MODEL OF ANCHOVY FISHERY 



revision in policy. The degree of sensitivity thus 

 determines which information is trivial and 

 which is critical. Parameters of the model which 

 prove to have little or no effect on the decision 

 then need not be refined by further research. 



ACKNOWLEDGMENTS 



The work was based on parts of two disserta- 

 tions in partial fulfillment of the requirements for 

 the Ph.D. degree at the University of Washing- 

 ton. Support for the project was provided by the 

 West Coast Fishing Industry Study, NMFS Con- 

 tract No. 14-17-0007-1118, with James A. 

 Crutchfield, University of Washington, as princi- 

 pal investigator. 



We are indebted to the late G. J. Paulik, Uni- 

 versity of Washington, for his continuous encour- 

 agement and support throughout all aspects of 

 the research and analysis which led to the com- 

 pletion of this study.
