STANDARD and CHITTENDEN: REPRODUCTION, MOVEMENT, AND POPULATION OF BANDED DRUM 



young-of-the-year recruit inshore. Newly age I and 

 older fish were most abundant at 13-24 m in 

 November-April (Fig. 10A, B). Few were captured 

 at 5-9 m then. 



Age Determination and Growth 

 Few spawned groups of L. fasciatus exist at any 



one time in the northwestern Gulf and only one 

 normally predominates. No more than three 

 spawned groups were present at any time (Fig. 6). 

 This maximum occurred only in August 1980 

 and June-July 1981 when spring-spawned fish 

 recruited to join two fall-spawned groups. These 

 were the only occasions when spring-spawned fish 

 were clearly identifiable and their abundance was
