 age spawning stock biomass-per-

 tion of refuge size !/?,> and fishing 

 mortality rate (F, ) when transfer rate 

 i T, i is constant: (A) damselfish ( 7",. = 

 0.01 1; (B) surgeonfish iT,, = 0.251; and 

 (C) the jack (7,, = 0.5). Spawning bio- 

 mass values are expressed as a per- 

 centage of virgin biomass that would 

 accrue if no fishing were allowed in 

 areas 1 and 2.
