Figure 3. — Stages of atresia following after complete yolk absorption (bar = 0.1 mm), a) and b) Typical beta (/i) stage atresia. Note the 

 disorganized granulosa cells with some pycnotic nuclei (p) or intracellular vacuoles (v) (t = outer layer of thecal cells, c = intercellular 

 cavities), c) and d) Disintegration of granulosa continues in these older beta (fi) stage atresia. Note the large intercellular cavity (c) 

 and the prominent, contracted thecal cell layer (t). Also present is an unyolked oocyte in early alpha (Ua) stage and several delta (8) 

 stage atresia cells, ei Two types of gamma (y) atresia seen in northern anchovy ovaries. Note flocculent material (f) and the thecal 

 layer (t). f) Delta (6) stage atresia characterized by dark yellow fine granular pigment and an irregular nucleus (n).
