Hypothesis
Chronic ammonia stress negatively impacts liver tissue structure, enzyme activities, and metabolome in juvenile Micropterus salmoides.
Conclusion
Chronic ammonia exposure leads to significant liver damage and metabolic changes in juvenile Micropterus salmoides, suggesting that ammonia levels above 4 mg/L should be limited to 7 days in aquaculture.
Supporting Evidence
- Ammonia exposure caused oxidative stress in the liver of juvenile Micropterus salmoides.
- Significant decreases in antioxidant enzyme activities were observed with increasing ammonia concentrations.
- Metabolomic analysis revealed alterations in liver metabolites due to ammonia stress.
- Histological examination showed liver tissue damage at all tested ammonia levels.
Takeaway
Too much ammonia in the water can hurt fish livers, so we need to keep it low to keep them healthy.
Methodology
Juvenile Micropterus salmoides were exposed to different ammonia concentrations for 28 days, and liver tissues were analyzed for structural and metabolic changes.
Limitations
The study focused only on juvenile fish and specific ammonia concentrations, which may not represent all conditions in aquaculture.
Participant Demographics
Juvenile Micropterus salmoides from Chongqing Municipal Factory Agriculture Research and Development Center.
