Development and evaluation of the effectiveness of microbial formulations for nitrite removal in aquaculture systems

Abstract

Nitrite pollution poses a serious threat to aquaculture systems, affecting the health and growth of aquatic organisms. This study focuses on the development and evaluation of microbial formulations designed to enhance nitrite removal in aquaculture environments. Various microbial formulations, utilizing selected nitrite-reducing bacterial strains, were created and tested under both controlled laboratory conditions and actual aquaculture systems. The effectiveness of each formulation was assessed based on its ability to reduce nitrite levels, alongside monitoring other water quality parameters such as pH, temperature, and dissolved oxygen. The results indicated that the formulations achieved up to 90% reduction in nitrite concentrations, with minimal impact on overall water quality. These findings highlight the potential of these microbial formulations for improving water quality management in aquaculture systems and promoting sustainable fish farming practices. Future work will focus on optimizing formulation stability and evaluating long-term effects on aquatic ecosystems.
