At the moment, there is no federal standard for labeling fish as
"organic." While cows, pigs, chickens and all sorts of other animals can
easily meet existing standards by being fed specific types of food and not
getting any hormones or antibiotics added to them, fish are much harder to pin
down. Part of the problem lies in the fact that many fish are carnivorous and
because there are currently no organic fish, they cannot eat organic feed.
Additionally, to ensure that fish are only eating organically, which is not a
problem for herbivorous fish, they must be supervised and receive specific feed.
If fish have to be supervised to get the "organic" designation, that means that
wild fish will not qualify, which is a sticking point for those who actually
fish wild fish.
