FISHERY BULLETIN: VOL. 78, NO. 2 



Most economic models of fishery management 

 have ignored the influence of landings on the 

 price of fish or fishery products. The assumption 

 of fixed price is a particularly attractive one, be- 

 cause with fixed prices the harvest quantity is 

 proportional to the total revenue. Only the rela- 

 tionship between costs and landings must be 

 added to the model in order to derive economic 

 critertia for optimization. When management 

 programs control landings which are large rela- 

 tive to the market demand, however, the price is 

 likely to become a variable rather than a fixed 

 parameter. The use of demand relationships, such 

 as the one estimated above, will undoubtedly be- 

 come important as more control is exercised over 

 more fisheries in the United States. The means 

 for incorporating demand analysis into fishery 

 management models is explained by Anderson 

 (1973) and Clark (1976, chapter 5). More extensive 

 use of these complex models which include vari- 

 able prices will proceed only as fast as the devel- 

 opment of solid, empirical demand studies.
