Abstract
The yolk nucleus in the young oocytes of the freshwater teleost Noemacheilus barbatulus (L.) was investigated by electron microscopy. Yolk nuclei are only found in stage I. They consist of nucleolar substance, mitochondria and partly of dictysomes.

The yolk nuclei of Noemacheilus doesn't have any relations to the formation of yolk.
