 estimating mean increment count of an 

 individual Atlantic menhaden larva.

of increment width of larvae from duplicate control and 

 treatment tanks were pooled. Prior to starvation, no 

 significant differences (/j>0.05) were observed in mean 

 increment width between larvae from control and 

 treatments except for the control and 3-day starved 

 treatment in the older age class. The mean width of 



growth increments differed significantly (/)<0.05) 

 between fish from control and treatments during the 

 respective periods of starvation and recovery (Fig. 3). 

 The width of growth increments was significantly 

 larger in fed compared with starved larvae. In general, 

 the magnitude and significance of these differences
