The aquaculture industry’s rapid growth to meet commercial demand can trigger an outbreak of infectious diseases due to high-density farming. Antibiotic overuse and misuse in fish farming and its global health consequences have led to searching for more natural alternatives such as medicinal plants. In this sense, garlic (Allium sativum) has different bioactive compounds with biological properties for animal health. Among them are the ajoene, alliin, and allicin, which confer biological properties such as growth promotion, antimicrobial, antiviral, antioxidant, and antiparasitic. Ways to use garlic in aquaculture include oil, fresh mash, aqueous extract, and garlic powder. The powder presentation is the most used in aquaculture; it is generally applied by oral administration, adding to the feed, and the dose used ranges from 0.05 to 40 g/kg of feed. Garlic has been used in the aquaculture of different species such as rainbow trout (Oncorhynchus mykiss), spotted grouper (Epinephelus coioides), catfish (Clarias gariepinus), tilapia (Oreochromis niloticus), guppy fish (Poecilia reticulata), goldfish (Carassius auratus), and barramundi (Lates calcarifer). In addition to its properties, garlic’s usage became popular, thanks to its low cost, easy incorporation into food, and little environmental impact. Therefore, its application can be an effective solution to combat diseases, improve organisms’ health using natural supplies, and as an alternative to antibiotics. This review reports and discusses plant-derived products’ beneficial properties, emphasizing garlic and its usages in fish aquaculture.

水产养殖业为满足商业需求而快速增长，可能会因高密度养殖而引发传染病的爆发。养鱼业中抗生素的过度使用和误用及其对全球健康的影响促使人们寻找更天然的替代品，例如药用植物。从这个意义上说，大蒜（Allium sativum) 具有不同的生物活性化合物，具有动物健康的生物学特性。其中包括阿霍烯、蒜氨酸和大蒜素，它们具有促进生长、抗菌、抗病毒、抗氧化和抗寄生虫等生物学特性。在水产养殖中使用大蒜的方法包括油、鲜醪、水提物和大蒜粉。粉剂在水产养殖中使用最多；一般采用口服给药，加入饲料中，用量为0.05～40g/kg饲料。大蒜已用于不同物种的水产养殖，例如虹鳟鱼 ( Oncorhynchus mykiss )、斑点石斑鱼 ( Epinephelus coioides )、鲶鱼 ( Clarias gariepinus )、罗非鱼 ( Oreochromis niloticus ))、孔雀鱼 ( Poecilia reticulata )、金鱼 ( Carassius auratus ) 和尖吻鲈( Lates calcarifer )。除了它的特性外，大蒜的使用也很受欢迎，因为它成本低、容易融入食物中，而且对环境影响很小。因此，它的应用可以成为对抗疾病的有效解决方案，利用天然供应改善生物体的健康，并作为抗生素的替代品。本综述报告并讨论了植物衍生产品的有益特性，重点介绍了大蒜及其在鱼类养殖中的用途。
