Comparison of the appearance of ot-atretic advanced yolked oocytes of a fully 

 developed Atlantic croaker, Micropogonias undulatus, in a histology slide (A), 

 and in a smear of fresh oocytes under a dissecting scope (B) and (C). Cy=clumping 

 of yolk globules; Pc=peripheral cytoplasm; Va=vacuoles. Bars=0.1 mm. 



(Welsh and Breder, 1923; Wallace, 1940; Johnson, 

 1978; Colton et al., 1979; Morse, 1980) describe a 

 protracted spawning season, extending from July/ 

 August through November/December, with peak 

 spawning during September/October. However, re- 

 ports of spawning from September/October through 

 March/April along the South Atlantic Bight (Hilde- 



brand and Cable, 1930; Bearden, 1964; Warlen, 1982; 

 Lewis and Judy, 1983) indicate that south of Cape 

 Hatteras, North Carolina, spawning seems to start 

 a little later and to continue through early spring, 

 perhaps as a result of the southward late summer/ 

 early fall migration of Atlantic croaker (Hildebrand 

 and Schroeder, 1928; Wallace, 1940; Haven, 1959).
