"Fishing hydraulic engineering" is a unique work written by Arinzhanov A. E. which immerses the reader in a world where the sciences of fishing, ecology, and engineering intersect. This book will be a real discovery for all who are interested in water resources, their rational use and conservation of biodiversity. The author focuses on issues related to the design and operation of hydraulic structures, which play a key role in fisheries. Arinzhanov not only describes the technical aspects, but also focuses on the environmental consequences, which makes his work especially relevant in light of the current challenges associated with climate change and the depletion of natural resources. The reader will be able to learn about how to properly organize fish ponds, what technologies are used to improve the living conditions of aquatic organisms and how to minimize the negative impact of human activities on ecosystems. The book will be of interest not only to professional fish farmers and environmentalists, but also to students studying water resources, as well as to everyone who is fond of nature and wants to understand how to harmoniously combine the development of fisheries with concern for nature. The age category of readers can range from high school students interested in biology and ecosystems to adults working in the field of ecology and fisheries. The topics raised in Fisheries Hydrotechnics cover a wide range of issues: from the design and construction of water bodies to the management of their operation taking into account biological and environmental factors. Arinzhanov raises important questions about how to preserve biodiversity, what methods of fish breeding are most effective and how to use modern technologies to improve the living conditions of aquatic organisms. This makes the book not only a practical tool, but also a valuable source of knowledge for all those who strive for sustainable development in the field of fisheries. Arinzhanov’s style is distinguished by clarity and accessibility, which allows the reader to easily assimilate complex concepts and ideas. The author uses many examples from practice, which makes the material more clear and understandable. His previous work is also noteworthy, as it addresses important aspects of ecology and natural resource management. If you are interested in topics such as sustainable development, the ecology of reservoirs and fisheries, you will definitely find in his books a lot of useful and inspiring. “Fisheries” is not just a textbook, but a real encyclopedia of knowledge for everyone who wants to understand more deeply how aquatic ecosystems function and how they can be effectively managed. This book will be a reliable companion for those who seek harmony between man and nature, as well as for those who want to contribute to the conservation of water resources for future generations. If you are looking for literature that combines a scientific approach and practical application, then Arinzhanov’s Fishery Hydrotechnics will be your faithful assistant in studying and mastering this important area. Do not miss the opportunity to immerse yourself in the world of fisheries hydrotechnics and discover new horizons of knowledge!
