The work presents microstructural analysis of the oocytes of the common carp and the caspian roach that are on the stages of the protoplasmic and trophoplasmic (large) growth of the germ cells. Seasonal changes of quantitative and qualitative transformations of structural components of oocytes are also given. It is shown that from the early spring to the late autumn in the ovaries of the caspian roach and the common carp found are the oocytes of different generations, which are both at the generative and vegetative stages of growth of germ cells and along with this can occur, with varying intensity, resorption of whole oocytes and their individual structures. It has been established that spawning is common in the common carp, generative and regenerative processes occur simultaneously, while in the wobble spawning is simultaneous, the generative processes begin only after the regeneration of the sexual gland.
