One final point sonny boy, the only way many salmon and trout farmers
could meet regulations for their toxic fish, was by cutting off all
the fatty parts and selling the rest. The removed parts were supposed
to be dumped as toxic waste, but a few farmers were found feeding this
back to the fish.

There are still only a couple of extremely expensive solutions for
replacing fishmeal in salmonid diets, and none of them is available on
the massive scale required.
