Influence of photoperiod and temperature manipulation on gonadal development and spawning in Caspian roach (
            Rutilus rutilus caspicus
            ): Implications for artificial propagation

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.

In this study, changes of pH, ionic (Na+, K+, Ca2+,and Mg2+), biochemical (total protein, glucose, and cholesterol)compositions of seminal plasma, sperm motility traits (percentage of motile spermatozoa and sperm movement duration), and sperm production characteristics (sperm volume, spermatocrit, and sperm density) were studied in Caspian roach, Rutilus rutilus caspicus, during spawning migration. Sperm of 10 males was collected three times during the spawning migration (in February, March, and April). The results showed that sperm motility parameters (percentage of motile spermatozoa and sperm movement duration) changed significantly (P < 0.05) during the reproductive season, but sperm density, spermatocrit, and sperm volume did not show significant differences during spawning migration. Analyses performed at each sampling time (February, March, and April) showed significant differences (P < 0.05) in calcium,magnesium, potassium, and cholesterol, whereas there were no significant changes in Na+, pH, total protein, glucose, and cholesterol.
