Dentzau and Chittenden Population dynamics of Folydactylus octonemus in the Gulf of Mexico 459 



ity over a variety of species supports the suggestions 

 (Chittenden and McEachran 1976, Chittenden 1977) 

 that fishes of the white and brown shrimp communities, 

 at least in the northwestern Gulf, have evolved a com- 

 mon pattern of population dynamics which stresses 

 small size, early maturity, short life spans, high mor- 

 tality rates, and rapid turnover of biomass.
