calculated from caloric and respiration data, and 

 estimates of volume searched and feeding suc- 

 cess. These calculations indicated that anchovy 

 larvae just after yolk absorption require up to 

 37 times the food density as older larvae. Thus, 

 just after yolk absorption anchovy larvae are 

 more vulnerable to death from starvation than 

 at any other time during the larval stage, 



ACKNOWLEDGMENTS 



David Holts assisted in all but the work on 

 feeding success which Gary Thomas assisted. 

 Alan Good wrote the program used to analyze 

 the swimming behavior of larvae and the one 

 used to analyze observational data collected on 

 paper tape. James Zweifel fit various models 

 to the swimming data.
