Abstract Nitrite is a common pollutant in aquatic environment， which is also toxic to aquatic organisms. Flounder plays an important role in aquaculture at home and abroad and is widely cultivated intensively. In this paper， the source， toxicity mechanism and toxicity influencing factors of nitrite to aquaculture were reviewed. This paper also discussed the effects of nitrate on tissues and organs， stress response， physiological function， immune response and cell apoptosis of flounder.
