I am thinking of setting up a 10 gal. and seeing if I can find a fish at one of the many LFS's in my area that has Cryptocaryon and trying this Garlic and Ginger mixture. Of course I am going to feel bad if the fish dies wondering if I should have just tried the copper and or the hypo. ATJ, what do you suggest someone like me, not having much education on such matters, doing if I was wanting to try something like this?
The biggest problem with studying something like this is ensuring that the results are both conclusive and unambiguous. The education level of the person doing the study makes little difference and what is important is the construction of the study.
The observations in this thread have been both useful and promising, and as the thread title states, ginger is a possible cure for "Ich". Unfortunately, the observations are neither conclusive nor unambiguous. Note that this is not at all a comment on the people that made the observations or their abilities, but more to do with the unanswered questions. Were the fish really infected with
Cryptocaryon, or was it something that looks very much like it? Did the fish recover through acquired immunity and could they have recovered without any treatment? Does the amount of ginger provided matter and if so, how much is required? Does the preparation of ginger matter? There may be other questions that I can't think of at the moment.
Certainly, the more successes people have with this treatment, the more it suggests it is effective, however, how should failures be evaluated? Do they indicate that ginger is not effective? Was the ginger prepared incorrectly? Was insufficient ginger provided? Was a pair of maroon clowns present?
To make the results more conclusive and less ambiguous, the above questions need to be considered when devising a study. A study along the lines of what Steve mentioned would probably be the best, i.e. use a large number of fish and feed half with garlic/ginger and the other half not and then statistically compare the results. While that sounds simple enough, to ensure unambiguous results, you'd have to:
* show that both groups of fish were exposed to
Cryptocaryon and only
Cryptocaryon
* expose both groups of fish to the approximately the same number of
Cryptocaryon theronts
* determine if the fish that recovered in either groups are still able to host trophonts
There may even be some value of splitting the fish into 4 groups, one without ginger treatment and the other three with varying quantities of garlic/ginger, or with garlic alone, ginger alone and both. The variations can be quite exhaustive.
I'm guessing this is not exactly what you had in mind, but unfortunately is the sort of depth that needed.
