Photomicrographs of histological sections of ovarian atresia and the inactive reproductive stage in mature 

 female striped mullet (Mugil cephalus L.). I A) Alpha-stage oocyte atresia, scale bar=100 um; (B) Late 

 alpha-stage oocyte atresia, scale bar=100 ,um; (C) Beta-stage oocyte atresia, scale bar=100 um; ID) Early 

 gamma-stage oocyte atresia, scale bar=100 ,um; (El Gamma-stage oocyte atresia, scale bar=100 um; iFl Late 

 gamma-stage and early delta-stage oocyte atresia, scale bar=100 um; iGi Delta-stage oocyte atresia, scale 

 bar=100 um; (H) Reproductively inactive striped mullet ovary with degraded cellular material from previ- 

 ous spawning, scale bar=100 um. Labels: YG = yolk globules; VAC = vacuoles; AO = atretic oocytes; COL = 

 collapsed outer cell layers; UO = undeveloped oocytes; BV = blood vessels; OSM = old spawn material;
