Diagnosis
Although a Vibrio infection can be suspected given
certain case histories and clinical signs, proper diagnosis
requires isolation of the bacteria and its identification. If
you are unable to perform these tasks yourself, live,
diseased fish should be delivered to a diagnostic
laboratory familiar with fish diseases to confirm the
infection, identify the species of Vibrio, and perform an
antibiotic sensitivity test. Contact your county extension
agent for assistance on where and how to submit samples
