Farmed fish and shrimp are continuously challenged by multiple stressors during their life stages, such as hypoxia, pH fluctuations, different salinities, high nitrite, un-ionized ammonia, injury during handling, inadequate nutrition, or food shortage, which can eventually adversely impact their health, welfare, and growth rates. Besides, these stressors can weaken production and decrease their resistance to diseases. Scientists and researchers have been making concerted efforts to find new, safe, and inexpensive supplements to mitigate the negative influences of stressors and thereby enhance the productivity of farmed aquatic animals. Some microalgae are microscopic unicellular organisms that were found to be promising feed supplements due to their richness in important nutrients such as minerals and vitamins. Moreover, some microalgae contain several bioactive phytochemicals that exhibit anti-inflammatory, antioxidant, and immunomodulatory properties. Several field-controlled studies provided evidence that using microalgae as feed supplements led to improved growth, physiological functions, immunity, antioxidant capacity, and disease resistance in farmed finfish and shellfish species. This review article emphasizes the beneficial role of the cyanobacterium Arthrospira platensis and seven microalgal species, including Chlorella vulgaris, Parietochloris incisa, Dunaliella salina, Aurantiochytrium sp., Haematococcus pluvialis, Tetraselmis sp., and Nannochloropsis oculata in mitigating stress effects in farmed finfish and shellfish species. The conclusions of this article throw light on the potential benefits of using microorganisms in aquaculture.

养殖鱼虾在其生命阶段不断受到多种压力源的挑战，例如缺氧、pH 波动、不同盐度、高亚硝酸盐、非离子氨、处理过程中受伤、营养不足或食物短缺，最终可能对其产生不利影响。健康、福利和增长率。此外，这些压力源会削弱生产并降低其对疾病的抵抗力。科学家和研究人员一直在共同努力寻找新的、安全且廉价的补充剂，以减轻压力源的负面影响，从而提高养殖水生动物的生产力。一些微藻是微观的单细胞生物，由于它们富含矿物质和维生素等重要营养素，因此被认为是有前途的饲料补充剂。而且，一些微藻含有几种具有抗炎、抗氧化和免疫调节特性的生物活性植物化学物质。几项田间对照研究提供的证据表明，使用微藻作为饲料补充剂可以改善养殖的有鳍鱼类和贝类物种的生长、生理功能、免疫力、抗氧化能力和抗病性。这篇评论文章强调了蓝藻的有益作用Arthrospira platensis和七种微藻，包括小球藻、Parietochloris incisa、杜氏盐藻、Aurantiochytrium sp.、雨生红球藻、Tetraselmis sp.和Nannochloropsis oculata ，可减轻养殖鱼类和贝类物种的应激影响。本文的结论揭示了在水产养殖中使用微生物的潜在好处。
