Nanoparticles can get into the aquatic environment at different stages of the life cycle of water organisms and these interactions can cause an urgent need for the biochemical balance of the organism and the adaptation of the species to the changing environment. The goal of the current research is to investigate the effect of nanoparticles of Fe3O4 (20-30 nm) and Al (18 nm) on the processs of fertilization of sexual cells of rainbow trout (Oncorhynchus mykiss Walbaum) in the aquaculture condition and the effects of embryonic developmental stages after fertilization, as well as absorption of nanoparticles by feedstuffs and entry into the food chain and investigating possible bioaccumulation. According to the results of the experiments it was concluded that, when Fe3O4 (20-30 nm) and Al (18 nm) nanoparticles are added in roe of rainbow trout prior to fermentation, the percentage of fertilization of roe was higher, and the release of free embryos was higher than in the control variants. Fe3O4 (20-30 nm) nanoparticles have a stimulating effect at amount of 0.05 g (2018) and Al (18 nm) nanoparticles at the amount of 0.005 g (2018). It can be assumed that these nanoparticles have a catalytic effect on spermatozoid acrosomes, accelerate energy activity, and eventually increase the activity of spermatozoids, which leads to an increase in the rate of fertilization of the roe.
