review · Animals
Intensive aquaculture practices increase stocking density to raise yields, but this often leads to toxic ammonia accumulation in ponds, impairing animal growth and overall health. Yucca extract offers a practical approach to adsorbing waterborne ammonia and can be applied in rearing water or integrated directly into aquafeed as either a powder or liquid solution. Rich in steroidal saponins, polyphenolics, and resveratrol, yucca extract enhances feed utilisation, growth performance, and survival rates across several aquatic species. It also bolsters physiological condition by improving blood biochemical quality, antioxidant capacity, immune markers, and anti-inflammatory defences. Using yucca extract in aquafeed or pond water presents a protective management strategy to alleviate the damaging biological effects of ammonia build-up in high-density aquaculture systems.
High ammonia levels in intensive fish farming threaten stock welfare and productivity. Understanding how plant-derived extracts such as yucca can neutralise waterborne ammonia while simultaneously strengthening fish immunity and growth helps fish farmers maintain healthier stocks and support more sustainable intensive aquaculture operations without compromising animal health.
The findings point to direct applications for commercial fish farmers and aquafeed manufacturers, who can deploy yucca extract as a water treatment or feed additive in powder or liquid form. Because it relies on published data examining practical waterborne ammonia reduction, the approach appears applied and accessible for real-world testing and implementation in intensive pond systems.

In modern aquaculture systems, farmers are increasing the stocking capacity of aquatic organisms to develop the yield and maximize water resources utilization. However, the accumulation of ammonia in fishponds regularly occurs in intensive aquaculture systems, resulting in reduced growth rates and poor health conditions. The inclusion of yucca extract is recognized as a practical solution for adsorbing the waterborne ammonia. Yucca has abundant amounts of polyphenolics, steroidal saponins, and resveratrol and can be used as a solution or as a powder. In this context, this review aimed to investigate the possible regulatory roles of yucca extract on aquatic animals' performances. Concurrently, the feed utilization, growth performance, and physiological status of aquatic species can be improved. Additionally, the yucca application resulted in enhancing the antioxidative, immunological, and anti-inflammatory responses in several aquatic animals. Exclusively, the present review proposed a protective solution through the application of yucca extract in the aquafeed and rearing water of aquatic animals suffering from ammonia accumulation. Furthermore, it shows how yucca could enhance the growth, survival rates, blood biochemical quality, immunological indices, and the antioxidative capacity of aquatic animals in light of the relevant published data.
