Aeromonas Hydrophila Containment: Biosecurity Protocols for Preventing Dropsy and Hemorrhagic Septicemia
The Ubiquitous Bacterial Assassin
Aeromonas hydrophila is naturally present in all aquatic environments. It remains harmless until fish immune barriers crumble due to poor water quality, rough handling, or nutritional starvation.
Clinical Symptoms of Motile Aeromonas Septicemia (MAS)
- Extensive hemorrhages at fin bases and vent areas
- Abdominal dropsy (ascites) where fluid accumulates in the peritoneal cavity
- Exophthalmia (popeye) and lethargic surface swimming
Emergency Farm Containment Checklist
- Discontinue all sinking feeds that rot on pond floors.
- Flush tank water with 100% fresh, deep-well borehole supply.
- Disinfect nets, grading trays, and boots in 200 ppm iodophor solutions.
- Administer veterinary-prescribed antimicrobial therapy formulated with immune-stimulant beta-glucans and Vitamin C.
