Resumo

The present study is of practical significance as it aimed to analyze nitrite reduction through two management strategies, potentially leading to a proposal for controlling this compound and improving water quality in the BFT system. The study focused on achieving an optimal organic carbon-to-alkalinity ratio and an optimal feed rate in the rearing of P. paulensis. Two experiments were conducted. While the study did not conclusively develop a tool for nitrite reduction by oxidizing nitrite bacteria, it did find that higher alkalinities promote the action of ammonia-oxidizing bacteria, creating a more conducive environment for biofloc development and improved water quality control. In a study aimed at determining the optimal feed rate, it was observed that higher feed reductions (30%) enhanced the activity of nitrite-oxidizing bacteria, thereby accelerating the nitrification process and potentially revolutionizing shrimp farming practices.
