Abstract

In modern aquaculture, the increase in stocking density has led to the accumulation of ammonia in ponds, resulting in reduced growth rates and poor health conditions for aquatic animals. As synthetic chemicals often aggravate this issue, natural remedies like Yucca have gained attention for their potential benefits. Yucca, a plant from the Asparagus family, has long been used for various medicinal purposes and is now recognized for its effectiveness in controlling ammonia in aquaculture ponds. This plant contains compounds like saponins, phenolics, and steroidal substances that exhibit anti-inflammatory, antioxidative, and growth-promoting properties.

Yucca helps mitigate ammonia levels by acting as a pH regulator and supporting nitrifying bacteria that convert toxic ammonia into less harmful nitrites. Furthermore, Yucca enhances primary productivity by promoting the growth of plankton and improving dissolved oxygen (DO) levels at the pond's bottom. Its benefits extend to soil conditioning, waste decomposition, and odor removal. Through a series of trials, including lab and field tests, Yucca's efficiency in controlling ammonia and its positive effects on aquaculture have been confirmed.

Yucca SP, in particular, has demonstrated its role in improving water quality and animal health, highlighting its potential as a cost-effective and environmentally friendly solution for aquaculture management. The results support the use of Yucca as a valuable addition to aquaculture practices, enhancing both the welfare of aquatic animals and the overall health of the aquatic environment.
