TECHNOLOGY OF INCREASING THE AMOUNT OF PROTEINS AND PROTEINS IN FISH FEED USING BIOTECHNOLOGICAL METHODS

This article is devoted to technologies for increasing the amount of proteins and proteins in fish feed based on biotechnological approaches. The study analyzes the possibilities of using fermentation, bioconversion using microorganisms (bacteria and fungi), enzymatic hydrolysis, and probiotic and prebiotic additives. These methods serve to improve the digestibility of feed raw materials, increase the share of essential amino acids, and increase their biological value. As a result of biotechnological processes, the feed utilization coefficient increases, the growth rate and health of fish improve. The article also discusses the issues of reducing production costs and ensuring environmental sustainability by partially replacing traditional protein sources. The conclusions obtained are of practical importance in establishing effective and innovative feed production in fisheries.本文聚焦于基于生物技术路径提升鱼类饲料蛋白质含量的相关技术。本研究分析了发酵技术、利用微生物（细菌与真菌）开展生物转化、酶解工艺，以及益生菌与益生元添加剂的应用可行性。上述方法可改善饲料原料的消化率，提升必需氨基酸占比，并提高饲料的生物学价值。经生物技术工艺处理后，饲料利用率得以提升，鱼类的生长速率与健康水平均得到改善。本文还探讨了通过部分替代传统蛋白源以降低生产成本、保障环境可持续性的相关议题。所得研究结论对于水产养殖业构建高效创新的饲料生产体系具有重要的实践价值。
