that's not entirely true. One of my hunting partners sells fish vaccines. He worked for Novartus for years and and currently works for AquahealthUSA. I asked him about the tilapia deal and here's his reply:

That is not true with no vaccines available for Tilapia. There is a USDA licensed vaccine for Columnaris that can be used in Tilapia. However this pathogen does not cause a lot of mortality in Tilapia. The main pathogen in tilapia is Strep. iniae and there is not a licensed vaccine for that pathogen.

Dick, tell Jerry I said "Hi" will ya? Is he moving ok with the new hip?

There are a couple of commercial vaccines available for Tilapia, but of course, vaccines are not anti-biotics, they prevent us from having to use anti-biotics.

Autogenous vaccines (derived from a culture of the organism creating the problem on that individual farm site) have been instrumental in reducing the use of anti-biotics, and have saved several farms, including mine. FWIW, Dutch.
