The article presents studies on the morphological picture of the blood of fish in a comparative aspect, depending on age and species. In recent years, the influence of anthropogenic factors on the ecosystem of water bodies has intensified. In this regard, the main direction of solving the problems of ichthy -epizootological situations is new areas in veterinary medicine, in particular, hematological recognition of shaped elements in the blood of fish. To identify and understand the state of the fish organism, which they reflect, the researcher must first of all correctly determine these forms of cells in the blood, especially this applies to white blood cells. Our review is brief and does not pretend to be completely complete literature data on this issue. All this together gives a complex morphological picture of the blood of fish, which is difficult to typify. Unlike higher vertebrates, fish lack bone marrow and lymph nodes, hematopoiesis occurs both in organs, which include reticular syncytium (gill apparatus, kidneys, lymphoid organ), and vascular endothelium of the gill apparatus and heart and spleen and, in some cases, intestinal mucosa. In bone fish, the anterior part of the kidneys is the main organ of hematopoiesis; hematopoiesis also occurs in the lymphoid organs and in the spleen. The purpose of this research is to study the morphological picture of the blood of fish in a comparative aspect, depending on age and species. 3-7 animals from each age group of fish were examined on average. To study the morphological composition of blood from fish, blood was taken from gill vessels and from the heart cavity. In the process of research, it was found that the peculiarity of fish is the presence in the blood of both mature and young red blood cells, red blood cells have nuclei. Bony fish have four types of myeloid cells at all stages of development, known in the hematology of higher vertebrates and humans. A distinctive feature of fish granulocytes is the ability to observe leukocytes in all successive stages of filling the cytoplasm with granules, and the nucleus of th ese cells is very rarely lobed. Unlike fish, in mammals it is very difficult to distinguish between the stages of development of basophils and eosinophils (myelocytes, juvenile, stab and segmented), since the segmentation of the nucleus is weakly expressed , and the number of granules does not increase as the cells mature. It can be noted that the studies initiated can contribute to determining the choice of hematological studies. Given the above factors, a detailed epidemiological classification of hematolo gical studies will be obtained. The research results make certain additions to the procedures of veterinary-hematological studies in the field of ichthyopathology. In the future, research will continue in the direction of hematological diagnosis of fish di seases and prerequisites will be created for a detailed epidemiological classification of hematological studies.

This article discusses the issues of ensuring the confidentiality of personal data in the context of the development of the information society. The purpose of the article is to study the problems of ensuring the confidentiality of personal data in the Republic of Kazakhstan in the conditions of digitalization of the economy and society. The methodological basis of this research is based on General scientific methods: philosophical, dialectical, synergetic, inductive, deductive, method of analysis and synthesis, formalization, analogy, materialistic and empirical methods that ensure the integrity and balance of research, as well as a formal legal method that allowed an adequate analysis of the content of the personal data protection system in foreign countries and Kazakhstan. The processes of globalization, information openness and digitalization have set a number of tasks aimed at solving the problems of ensuring information security while maintaining a balance of interests of the individual, society and the state. In this regard, the problems of ensuring the security of personal data turnover on the Internet, today, is relevant for science and law enforcement practice. The current legislation of the Republic of Kazakhstan on personal data does not pay enough attention to issues related to the processing of personal data in information systems. Improving the legislation of the Republic of Kazakhstan in the field of ensuring the security of personal data processing on the Internet is relevant in the framework of implementing the provisions of the Cybersecurity concept («Cyber shield of Kazakhstan»). However, national legislation does not provide specific guarantees against unauthorized collection of personal data. The current legislation of the Republic of Kazakhstan in this sphere of relations contains a number of legislative decisions, but there are legal errors that require timely adjustments, taking into account the borrowing of progressive experience of foreign countries. Special attention in this article is on the study of contemporary threats of violations of personal data, and provided ways to protect them. The authors conclude that, despite the fact that the law of the Republic of Kazakhstan «On personal data and their protection» sets requirements for the procedure for ensuring the confidentiality of personal data, at the same time they are general in nature and need further specification. In addition, there are a number of significant aspects that are directly related to ensuring the confidentiality of personal data, which have not yet received their proper legal regulation.
