Chronic stress of nitrite nitrogen on Penaeus vannamei
This study set up a 0 to 10 mg/L gradient stress for 7 days, systematically evaluated growth and survival, physiological and biochemical indicators of gill tissue and hemolymph, and morphological changes in gill tissue. It also combined transcriptomics and metabolomics to analyze key pathways and molecular response characteristics, providing a basis for early warning of nitrite risk and water quality management in low-salinity aquaculture.
