MANOOCH: REPRODUCTIVE CYCLE OF RED PORGY 



tial, theoretically, is higher than a female's at 

 larger sizes, and conversely, a female's reproduc- 

 tive potential is higher than a male's at smaller 

 sizes. The female reproductive capabilities could 

 continue to increase with age. Perhaps males 

 function more efficiently at larger sizes because 

 they can mate with numerous females. Evolution- 

 ary factors which favor protogyny are those which 

 tend to depress male reproductive potential at 

 early ages, such as inexperience, territoriality, or 

 female mate selection (Warner 1975). Without 

 additional information on the spawning behavior 

 of Pagrus, it would be difficult to eliminate any of 

 these factors.
