HUNTER and ROE THE SPAWNING ENERGETICS OF NORTHERN ANCHOVY 



males may remain reproductively active for long- 

 er periods within the spawning season and may 

 not have as well defined spawning cycles as do 

 females. These differences are small relative to 

 the overall great similarity between the sexes. 



ACKNOWLEDGMENTS 



Gary Stauffer (SWFC), who developed one of the 

 original versions of the ration equation, provided 

 guidance in its application in the present study. 

 Carol Kimbrell (SWFC) carried out much of the 

 statistical analysis, collected some of the data, and 

 provided editorial assistance. The estimates of 

 spawning frequency are based primarily on the 

 careful histological analysis of Beverly Macewicz 

 (University of California, San Diego), and Thomas 

 Mickel (University of California, Santa Barbara) 

 assisted in laboratory work.
