<b>Histological characterization of oocyte developmental stages of suruvi <i>Steindachneridion scriptum</i> kept in captivity
Stages of oocyte development were described for suruvi females (Steindachneridion scriptum) kept in captivity. Oocytes of 21 mature or maturing females and ovaries of 12 immature females were fixed in Karnovsky solution for 4 and 12 hours, respectively. After, they were processed for routine histolo...
