What is the specific term for the disease Edwardsiella tarda causes in aquaculture species?
Answer
Edwardsiellosis
Edwardsiella tarda is widely recognized as a significant pathogen within aquaculture settings, where the disease it causes in various aquatic species, including channel catfish, eels, and salmon, is specifically termed Edwardsiellosis. This disease presents systemically in fish, often leading to visible signs such as hemorrhagic fins, abdominal swelling (ascites), loss of pigmentation, and the formation of internal abscesses within critical organs like the kidney and liver. In intensive farming, mortality rates linked to Edwardsiellosis can reach as high as 50%.
