Abstract
This study examined tissue-specific oxidative stress responses in juvenile Colossoma macropomum during 72 h of hypoxia (0.92 ± 0.37 mg L⁻1 O₂) followed by reoxygenation. The liver showed increased reduced glutathione (GSH) during hypoxia and recovery, while brain GSH remained stable, indicating differential antioxidant regulation. Lipid peroxidation (TBARS) decreased in the liver but increased in the brain during hypoxia, suggesting tissue-specific vulnerability. Hypoxia triggered feeding cessation, but full recovery occurred within 48 h post-stress. These findings underscore the resilience of C. macropomum to hypoxia, with targeted metabolic adjustments that could guide aquaculture strategies, such as stress-tolerant stock selection or optimized recovery protocols, to enhance productivity in oxygen-variable systems.
期刊介绍：
Aquaculture International is an international journal publishing original research papers, short communications, technical notes and review papers on all aspects of aquaculture.
The Journal covers topics such as the biology, physiology, pathology and genetics of cultured fish, crustaceans, molluscs and plants, especially new species; water quality of supply systems, fluctuations in water quality within farms and the environmental impacts of aquacultural operations; nutrition, feeding and stocking practices, especially as they affect the health and growth rates of cultured species; sustainable production techniques; bioengineering studies on the design and management of offshore and land-based systems; the improvement of quality and marketing of farmed products; sociological and societal impacts of aquaculture, and more.
This is the official Journal of the European Aquaculture Society.
