Kafudafish - excellent articles, I too read these, but they seem to relate to fresh water fish? From good research here I get the feeling salt water parasites can act wholly different to treatments?
I don't know and that is the $64,000.00 question.
I figure some of the reasons why this has not been really investigated much (could be wrong) is freshwater fish are usually cheaper and less expensive to maintain, freshwater aquaculture has been around for a long time thus is valuable such as catfish and trout, and a majority of the sw aquaculture around 90% is based upon oysters and salmon.
The other factor could be husbandry techniques such as open vs. closed systems i.e. large floating cages off shore vs. ponds that can get drained at harvest time.
If that demand has to be met by aquaculture techniques, then maybe the research would happen in the marine setting.
For the hobby and ornimental fish species breeding programs (even a smaller and younger world-wide profession) it would make sense if the magic bullet could be found. If you have a fish that brings in $10 profit then sure 5 cents of H2O2 is the cure all. If the fish brings in $1000.00 profit then you have a magic missle.
Cheap and effective methods have always been around. Rotenone is very effective as a piscicide; almost too good. Don't have any rotenone? Use black walnuts. It made things easy: you set the net downstream, put the posion above the pool and then you sat down and smoked or drank for a while.
But all of that is really outside the topic at hand and I apologize for that but I think some of the most informative discussions are circular instead of linear.
