WENNER AND WENNER: CRUSTACEANS FROM COASTAL HABITATS 



deviation from 1:1 during summer only (Table 6). 

 Male C. similis were found to have a greater aver- 

 age size (x CW = 69 mm, n = 2,130) than females 

 (5 CW = 61 mm. n = 2,294). Of the 2,128 female 

 C. similis examined for sexual maturity. 466 indivi- 

 duals were mature. Mature females ranged in size 

 from 41 to 114 mm CW. while immature females 

 were from 25 to 92 mm CW. 



Penaeus setiferus 



The white shrimp ranges from Fire Island, NY 



to Saint Lucie Inlet, FL and in the Gulf of Mexico 

 from the Ochlocknee River, FL to Campeche, Mex- 

 ico (Williams 1984). Along the Atlantic coast of 

 the United States, white shrimp are most abun- 

 dant in South Carolina, Georgia, and northeast 

 Florida where the species constitutes a substantial 

 commercial fishery (South Atlantic Fishery Man- 

 agement Council 1981). Within the region, white 

 shrimp are concentrated in waters <16.5 m (Ander- 

 son 1956), but abundance of Penaeus spp. appears 

 to be related to distance from shore with shrimp 

 most abundant within five miles of the coast line
