The main purpose of the present study is to study the effect of Fe3O4(20-30 nm) nanoparticles on common carp (Cyprinus carpio Linnaeus, 1758) aquaculture process before fertilization to germ cells (sperm, egg cell) and embryonic developmental stages after fertilization. The research material was implemented in between June-July 2021 at the Samukh-fish farm of the Republic of Azerbaijan. These nanoparticles were added to the germ cells (sperm, egg cell) of common carp (Cyprinus carpio Linnaeus, 1758) before fertilization in different amounts (0.0001 g, 0.001 g, 0.005 g and 0.05 g), as well as to the fertilized egg and their embryonic. Studies have indicated that when Fe3O4 (20-30 nm) nanoparticles are added to 0.0001 g and 0.001 g of common carp yeast (sperm) before fertilization, the fertilization rate of the eggs and the subsequent spawning of free embryos is higher than the control (59.12%) and was 61.65% and 71.45%, respectively. Fe3O4 (20-30 nm) nanoparticles have a stimulating effect in the amount of 0.05 g. It can be assumed that these nanoparticles in the specified doses have a catalytic effect on the acrosomes of sperm, accelerate energy activity and, consequently, increase the activity of sperm, which leads to an increase in the fertilization rate of eggs. Correspondingly, the results that obtained can be used to reduce weights, especially in the process of carp aquaculture, to reduce losses during embryonic development and increase overall productivity.
