organisms of similar nutritional value. The bay an- 

 chovy larva has low feeding and growth efficiencies, 

 but its food (in estuaries and coastal waters) is rela- 

 tively abundant. To compensate for low efficiency, 

 it is obligated to feed in high densities of prey. Fluc- 

 tuations in density of zooplankton prey in estuaries 

 might strongly influence survival and recruitment 

 to anchovy populations. The black sea bass larva 

 feeds and grows more efficiently. It has to because 

 its food (offshore) is not very abundant. The bay an- 

 chovy larva seems to be adapted to the high prey 

 densities, and the black sea bass larva to the low 

 prey densities, that characterize their respective 

 habitats (Theilacker and Dorsey 1980). The results 

 of this study parallel those of Houde and Schekter 

 (1983).
