FISHERY BULLETIN OF THE FISH AND WILDLIFE SERVICE 



inshore waters of this Continent. A specimen of 

 about 52 mm. (converted) reported by Smith 

 (1898: 98) from Woods Hole, Mass., August 10, 

 is the smallest specimen from northern inshore 

 waters that has been recorded. A 32.5-mm. 

 specimen, ANSP account No. 156 and 157, from 

 Guana Island, Virgin Islands, March 22, and a 

 34.8-mm. specimen, CBSFP account No. 171, 

 from Hog Island, Bahamas, March 28, are the 

 two smallest specimens to be recorded from inshore 

 collections. This is the approximate size by 

 which the preopercular spines have been absorbed. 

 The absence of inshore records of larvae and 

 smaller juveniles indicates that these periods are 

 spent in offshore currents. 



I believe the young in this area represent a 

 summer-to-fall population of larvae and juveniles 

 that drifts northward in the Gulf Stream, with 

 juveniles occasionally migrating or drifting in- 

 shore. This population appears to be largely the 

 result of recruitment from waters to the south of 

 this area, although some part may result from 

 reproduction within the area. Absence of records 



of bartholomaei from inshore waters along the 

 Atlantic coast of the United States during the 

 colder months of the year indicates that during 

 this period the species either returns to the south 

 or moves to warmer offshore waters. It is doubtful 

 that this species continues its movement with the 

 Stream to the east since it has never been recorded 

 east of the longitude of Bermuda along the route 

 of the Gulf Stream or from the Eastern Atlantic. 

 Spawning 



The spawning season that contributes larval and 

 juvenile bartholomaei to this area may be esti- 

 mated, from the smallest specimens taken in 

 March (12.7 mm.) and October (8.1 mm.), to 

 extend from mid-February to mid-September 

 (fig- 63). 



If, as suggested, there is a northward -drifting 

 population of developing young, the majority of 

 specimens taken by the Gill would probably have 

 been spawned to the south of this area. The 

 8.1 -mm. specimen taken in the Gulf Stream off 

 South Carolina (table 14) may have been spawned 

 in the southern portion of the area.
