The results of the numerical studies show that different species tolerate 

 different amounts of fishing. The effects of fishing are greatly compensated for 

 by the concomitant decrease in spawning stress mortality and increase in the 

 growth rate of the population. The growth rate of a stock biomass is a function 

 of the distribution of biomass with age. This distribution is affected by fishing 

 and by any disturbance in recruitment. When the recruitment to exploitable stock 

 is changed with partial fishing on not fully recruited year classes, and the 

 fraction of juveniles in the stock is affected by the change of larval recruitment 

 in direct proportion to the spawning biomass removed by fishing, the compensation 

 of the effects of fishing on the biomass are decreased, but not eliminated, and 

 "overcompensation" can still occur in species where the fraction of exploitable 

 stock is of the same size or smaller than the fraction of prefishery juveniles 

 (e.g., yellowfin sole). Further, this study suggests that density dependent 

 predation is not a linear function of prey density, and that recruitment to 

 exploitable biomass is a function of both spawning biomass and cannibalistic 

 predation on juveniles.
