FIG. 19. Net earnings'^ of (U. S.) Puget Sound net fisheries when 

 the sockeye and pink runs are twice their "standard" 

 sizes as a function of the amount of gear fished. 



'■"Net earnings is defined as the gross value of the catch minus all fixed costs and 

 operating costs. Labor costs have not been subtracted from the net earnings figure. 

 Net earnings is the amount of profit that is available for division between labor and 

 capital. 



intensities can result in ahernate over-fishing and under-fishing of a 

 series of races that pass rapidly through the fishery. The return from 

 this kind of regulation can result in numbers of progeny below the 

 reproductive capability of the parent stocks. 



Short fishing periods hinder the management agencies in their 

 task of getting information on the status of the runs. The result of 

 regulation with insufficient information can result in management de- 

 cisions more conservative than needed or, on the other hand, decisions 

 that reduce needed escapement. In either case, the price paid is re- 

 duced returns from races that have been over- or under-fished.
