concentrated in this area in winter. The 

 authors hypothesized that larval dispersal 

 from the Apalachicola area takes place 

 along clockwise (Lood) currents that 

 eventually wash onto the Florida Shelf 

 (Figure 28). '^oea larvae then disperse 

 along the coast, with the megalops stage 

 settlinq into the coastal estuaries. 

 Livingston et al. (1°77) used daytime 

 trawling to estimate winter populations of 

 juvenile blue crabs in the Apalachicola 

 estuarv of approximately 30,000,000 

 individuals. Miqration of spawning 

 females aopears to coincide with flooding 

 of the north Florida drainaae system, 

 which makes particulate organic matter 

 available as food to the young crabs 

 (Lauqhlin 107Q). Thus, the migration of 



blue crabs along the gulf coast could be 

 tied to both the reproductive 

 characteristics of the species and the 

 trophic organization of the Apalachicola 

 estuary. 



Life-history features of the dominant 

 epibenthic soecies in the Apalachicola 

 estuary have the same patterns as 

 elsewhere in the northern Gulf of Mexico 

 (Table 17). Spawning and recruitment 

 generally vary from species to species 

 according to different combinations of 

 seasonal physical factors. The bay 

 anchovy is the most abundant fish and is 

 one of the few fish species that does not 

 show regular seasonal recruitment 

 progressions. In contrast, the Atlantic
