dance in the coastal zone at depths from 11 to 37 

 m (South Atlantic Fishery Management Council 

 1981). 



Pink shrimp were the least abundant Penaeus col- 

 lected in this study (Table 1). They were collected 

 in 101 of the 303 trawl tows made. The stratified 

 mean catch per tow was highest for collections in 

 spring when 0.15 individuals per tow were collected 

 (Table 5). During spring, catches were highest in 

 strata off Florida (Fig. 4). The average size of pink 

 shrimp was greatest in spring (J TL = 121 mm, 

 n = 502). Mean sizes during other seasons were 

 winter (x TL = 113 mm, n = 11), summer (x TL 

 = 95 mm, n = 101), and fall (ic TL = 106 mm, n 

 = 209). Average total length decreased from 

 northern to southern areas as follows: North Caro- 

 lina/South Carolina (x = 119 mm, n = 256), 

 Georgia (i = 114 mm, n = 108), Florida (i = 111 

 mm, n = 459). 



The increased abundance and size of shrimp in 

 spring probably relates to their movement to the 

 nearshore zone then. In North Carolina, pink shrimp 

 emigrate from the estuaries in May and June, at 

 which time spawning takes place (Williams 1984). 

 Kennedy and Barber (1981) reported that movement 

 offshore of Cape Canaveral begins in April and May. 

 The larger average size of pink shrimp in spring 

 probably reflects the presence of roe-bearing 

 females in the coastal zone at that time.
