Activity: Buzzing
What
is Enteric
Septicaemia
of Catfish? ?
Definition of Enteric
Septicaemia
of Catfish
It is caused by
Edwardsiella
ictaluri
primarily Channel Catfish but has also been seen in carp, bass and others
The bacteria enter via the gut or snares
The bacteria can survive for long periods outside the host but is commonly found within the gut of apparently normal fish
It is highly contagious and pathogenic and causes losses of up to 50%
Signs and Symptoms of Enteric
Septicaemia
of Catfish
Usually
the condition has the appearance of typical
hemorrhagic
septicemia
However, acutely affected fish can be seen standing vertically in the water and spinning
Chronically affected fish may suffer from the open lesion on the head that earned the name “hole in the head disease”
Activity:
Brainstorming
are the treatment and preventive measures for Enteric
Septicaemia
of Catfish?
Pharmacological Treatment of Enteric
Septicaemia
of Catfish

Prevention
The
disease is prevented by;
Routine hygiene precautions are very important to control the disease.
Managing water quality,
Practicing biosecurity in the hatchery,
Using proper nutrition and feeding practices,
Administering drugs and chemicals appropriately
Vaccination
with immersion vaccines
Key Points
Enteric
septicaemia of catfish, or Hole-in-the-Head disease, is caused by the bacterium
Edwardsiella
ictaluri
, which belongs to the family
Enterobacteriaceae
Infected fish often show lethargic swimming, abnormal
behaviouralternating
listlessness and chaotic swimming, disorientation and swimming in spirals
Antibiotics should be administered under the guidance of a fish health professional or veterinarian
