Wild and domestic populations of channel catfish Ictalurus punctatus were examined to determine the distribution of the disease called enteric septicemia of catfish (ESC) in California. The causative agent of ESC, Edwardsiella ictaluri , was isolated from five separate sites in California. Two of these isolations were from rectal swabs of asymptomatic fish, confirming that a carrier state may exist. Normal‐appearing fish with serum antibody titer to E. ictaluri were commonly found in domestic channel catfish populations, suggesting that many fish become infected but recover. Wild channel catfish with antibody to E. ictaluri were also found in major reservoirs and water distribution canals. Edwardsiella ictaluri appears to be widely distributed within California.
