There are complete idiots out there in the world. People who do the most assinine
things on earth and sooner or later they end up in some emergency room as a result of
their total lack of regard of written instructions or any number of cautions.
A normal careful adult (the PORG) OTOH is going to be able to handle PP with no
problem at all. In fact I just mixed up a batch today for a friend and she got some
from a plumbing supply and it is sort of pellets not a powder. I advise people to
read the instructions here
http://users.megapathdsl.net/~solo/p....htm#POTASSIUM
before making up a batch. A stock solution is essential. Nobody should be
broadcasting PP over a pond, that is when both the human and fish are in danger. I
would bet that people with dead koi from PP have been dumping dry PP into their
ponds.
The antibody produced by fish is secretory IgM, NOT IgA.
" Detection of specific antibodies in the serum of animals is recognized as a useful
indicator of previous exposure to pathogens.
* ADL produces probes (AquaMab-F) to enable the detection of IgM by ELISA in a
range of fish species used in aquaculture. This is extremely useful for broodstock
health testing. It also provides tools for monitoring the immune response in fish
following vaccination and therefore will assist in the development of vaccines in the
future as the more fish species are cultured and new diseases emerge."

"Although infection with Ichthyophthirius multifiliis is often lethal, some fish
recover and develop resistance to subsequent infection. Under laboratory conditions
fish can be routinely immunized by exposure to controlled numbers of parasites. The
existence of acquired immunity against Ich provides the opportunity for the
development of protective vaccines. In addition, studies of the protective immune
response against Ich provide a useful model for the elucidation of the mechanisms by
which fish respond to pathogens which infect through epithelial surfaces.
Serum and mucus antibodies from immune fish immobilize free-swimming theronts
in vitro , suggesting several potential antibody-mediated mechanisms of protection.
For instance, antibodies in mucus could block penetration of theronts into the
epithelium of the skin and gills. Because immobilization can be readily observed in
the laboratory and fits a number of different models of potential mechanisms of
immunity, considerable effort in this laboratory has been dedicated to identifying
the target antigens responsible for this phenomenon, with the ultimate goal of
developing a subunit vaccine."

IgM is the most primitive type of antibody. But fish also have been found to produce
anti-micriobial proteins,

There is no data about use of salt prophylactically you are willing to accept. Rod
Farlee has posted all kinds of data, the fact that koi breeders use it, and Jo Ann's
teacher Dr. Ruth Floyd who advocates using salt .. not to mention that Jo Ann
advocates its use. And she most certainly is an expert. Ingrid

although I don't think any of us should be encouraging folks
without some training to use an oxidant like PP, I would hope!!
I just treated an individual in the ED 2 weeks ago
Although the slime coat has been shown to have IgA antibodies in it,
I can not tell you the number of burned gills I have seen on necropsy by the
use of PP in ponds, based on "calculated volumes" of the ponds.
because there
are still NO data (and read this answer fully please) that prove ROUTINE
salt use has ANY proven benefit in ornamental fish (Koi and Goldfish)
