OBJECTIVE: This study aims to elucidate the cause of mass mortality in Golden Trevally Gnathanodon speciosus at an aquarium and reports the first instance of gas bubble disease (GBD) in the species. Identifying the factors leading to this mortality event is intended to propose preventive measures for avoiding similar occurrences in the future.
METHODS: This case study involved the examination of Golden Trevally displaying symptoms of GBD, including abnormal swimming behavior, lethargy, and visible gas bubble formation in the cornea, aqueous humor, and oral mucosa. Necropsy and histopathology were conducted to assess the internal accumulation of gas bubbles in tissues. The etiology was investigated by analyzing the total dissolved gas (TDG) levels and inspecting the integrity of the water circulation system for structural defects.
RESULT: The affected Golden Trevally exhibited significant symptoms of GBD. Necropsy and histopathology confirmed the presence of gas bubbles in various tissues throughout the body. The analysis suggested that TDG supersaturation was caused by excessive microbubble formation due to structural defects in the water circulation system.
CONCLUSION: This case highlights the importance of practical TDG monitoring and maintaining system integrity to prevent GBD in aquaculture. Effective management of TDG levels is crucial to safeguarding the health of captive aquatic species.
