Time to go back to google. There's a place not far from here that
makes ingredients for fish food. The fish are processed to make
fillets and the guts, feathers fins and tails are used to make "wild
marine protein". In addition to fish they process a lot of Dungeness
crab nearby and the left over parts of the crab are ground up and made
into fish food. Those crab shells along with shrimp shells contain
some strange artifical chemical that cause the flesh of trout to turn
red.
I donīt need Google for that, but you need to learn to read, so hereīs
an extract and a link for you;

What Is Fishmeal
Fishmeal is a generic term for a nutrient-rich feed ingredient used
primarily in diets for domestic animals, sometimes used as a high-
quality organic fertilizer. Fishmeal can be made from almost any type
of seafood but is generally manufactured from wild-caught, small
marine fish that contain a high percentage of bones and oil, and
usually deemed not suitable for direct human consumption. These fishes
are considered 'industrial' since most of them are caught for the sole
purpose of fishmeal and fish oil production. A small percentage of
fishmeal is rendered from the by-catch of other fisheries, and by-
products or trimmings created during processing (e.g., fish filleting
and cannery operations) of various seafood products destined for
direct human consumption.

You might also look up "Industrial fishing" while you are about it.
