Mach when you suggested several months ago that this product could be a
problem didn't you also say that your experimental friends were also feeding
an assortment of other foods with the astaxanthin at the same time? And
that they were trying to raise the fish just as fast as they could in the
name of aquaculture? I think you are jumping to conclusions stating that it
is the astaxanthin that is causing the problems. There is a fish breeder on
the US west coast that is using this material by dusting his "oily" fishfood
and having fantastic results and none of the problems that you have eluded
to. I think that if you are going to make such a statement that you need to
have the people that performed the original experiments go back and repeat
it using only astaxanthin mixed with a good flakefood or some other sort of
prepared food. Reasonable feeding regiments also need to be in place as
bows could probably eat enough to kill themselves if given the opportunity.
