Abstract

Using morphological and cytological criteria, 5 types of early germ cells, i.e., primordial germ cells, spermatogonia and primary spermatocytes and oogonia and primary oocytes, were recognized in mullet by electron microscopy. These have been compared with other fish and vertebrates and the gonial potentialities evaluated.
