To study the embryotoxicity of the oil fraction Karakuduk locality (Kazakhstan, oil deposit) for zebrafish Danio rerio (family Cyprinidae), in the conditions of the experiment. The method of breeding fishes of Danio rerio, receiving, and incubating zebrafish in vitro. Experiments have been carried out on the development of Danio rerio embryos in the oil-bearing fraction (Karakuduk locality) in various in vitro concentrations. The paper presents the results of experiments on exposure zebrafish embryos (Danio rerio) oil fractions in different concentrations and shows data on mortality of embryos and embryonic development violations. The originality of studying embryotoxicity of petroleum products for Cyprinidae fish family is that the object of our experiment is the most vulnerable age group in the population-fish larvae. Due to investigations, number of eggs could exactly determine the vitality of the fish population in general and can counter the number of the population through a certain period. Following the epidemic of mass mortality of caviar and larvae from oil pollution, the toxicant acts in the role of the immunosuppressive agent. Thus, it leads to the reduction of resistance to various infections with the reduction of the variability of even slight temperature and salinity fluctuations.
