cur during summer only (Wilk et al., 1990). Fahay 
(1975) suggested however, on the basis of the range 
of larval lengths collected in 1967-68, that spawn- 
ing of P triacanthus may occur throughout the year 
in the SAB. The occurrence of larval and pelagic ju- 
venile Peprilus within our spring samples collected 
in the northern SAB suggests two possible scenarios: 
1) a species other than the most commonly found P 
triacanthus spawns within the Atlantic (e.g. P burti ) 
or 2 ) P triacanthus or P alepidotus has a more pro- 
tracted spawning season than previously thought. 
Peprilus larvae and juveniles in our samples proved 
to be P triacanthus; therefore, our results demon- 
strate an extended spawning period for P. triacanthus
