Efficacy of Vernonia amygdalina on Columnaris Disease Management and Growth Enhancement in Nile Tilapia

Abstract

Paper summary generated by OpenAI: This study investigates the efficacy of Vernonia amygdalina leaf as a natural alternative for managing columnaris disease and enhancing growth in Nile tilapia (Oreochromis niloticus). Over an eight-week period, varying concentrations of powdered V. amygdalina were added to aquaculture systems, with significant improvements observed in weight gain, feed conversion ratio, specific growth rate, and condition factor in treated groups compared to controls. Histomorphological analysis revealed enhanced intestinal tract morphology, and overall survival rates remained high, indicating the treatment’s safety and effectiveness. The findings suggest that V. amygdalina could serve as a cost-effective, environmentally friendly solution for promoting healthier fish production in aquaculture.
