There are some EXCELLENT posts by the ferret-specialist vet, Dr. Jerry
Murray, in the Ferret Health List Archives (which are VERY easy to search
at http://fhl.sonic-weasel.org/ ) on the IMPORTANT roles for health
maintenance that some of the fatty acids from fish can play. Just type
in "fish" and "AFERRETVET", and you'll find his posts:

On the other side, one would not want to give a diet that was mostly fish
without supplementing Vitamin E because in that case with someof the fish
yellow fat disease can be caused and kill the ferret, as may other but
slower possible nutritional problems.
Here ius a taste from a few quoted parts (I have his permission to
quote.) but do go read the entire things:
>As for diets: the higher the protein and the fat the better. Low fiber
>and low carbohydrates. Unfortunately your statement about ferrets being
>unable to digest corn is not accurate. Your comments about fish are
>also not accurate. Fish is highly digestable and a high quality protein
>source. It actually has a higher value than chicken! Plus it contains
>the important omega-3 fatty acids. Yes fish does smell like fish, but
>it is a good protein source! Wheat, Zupreem's main carbohydrate source,
>contains about 11.5% protein (actually higher than the protein content
>of corn ~9%). Wheat also has a higher post prandial (after meal) gluose
>response than corn. Better than rice better worse than corn! As for

>cooked eggs, Hill's a/d, and Gerber's baby food (chicken and turkey)
>You are right both Omega-3 and Omega-6 fatty oils are needed in the

There is MORE, so go read those! DO note that he is careful to use
qualifiers like "may" when something is hypothetical; and then go with
what hypotheses you choose to follow after reading a lot of info, and
always recall that degrees and levels of items can alter the effects; for
example it may be that complex carbohydrates over a certain amount can
have bad effects but lower than that won't have bad effects -- but the
actual amount remains unknown. Yes, you can do without fish and not
suffer as a result IF you supplement those fatty acids form another
source like flax seed oil, but be SURE to refrigerate that oil and keep
it away from lights and only buy a small amount at a time; it breaks down
rapidly. (Eating the GI tract of frogs may be one way that polecats get
fish indirectly -- but that is ONLY a guess and could be way off. For
all that I know of frog omega fatty acid components they may be direct
source.)
