The many names for the bacterial infection commonly known as Columnaris.
Dr Paul Bowser took us for much of today’s Aquavet lessons.
The many names for the one bacteria we now know as Flavobacterium columnare (Flavo = yellow, Column = rod shaped):
- 1. Bacterium columnaris –>
- 2. Chondrococcus columnaris (stupid name because they’re not coccoid at all) –>
- 3. Myxobacter columnaris –>
- 4. Cytophaga columnaris (Cyto = cell + Phaga = eating = cell-eating) –>
- 5. Flexibacter columnaris (because they flex as they move) –>
- 6. Flavobacteria columnaris –>
- 7. Flavobacter columnare.
As a measure of the wealth of experience he has in the field of aquatic animal health, he says he has been doing this since this bacteria had its second name. Even the great authors on the Wikipedia page on this bacteria doesn’t go that far back.

How do you repel birds from fish farms?
At one of the Aquavet classes, Dr Mark Fast presented some case studies and asked the class for some ideas on how to control digenetic trematode infection in fish. We could either work on the first intermediate (snail) host, or the final host (bird).
The bird control part generated most interest.
Following on from a previously posted topic on repelling birds,
there are a few more other ideas available.

Sea food at New Port, Rhode Island
After a day of whale watching, some of us escaped the cafeteria food to enjoy some local fresh seafood at Newport. It was an enjoyable meal shared with fellow students at Aquavet.
