I have also "heard" that porcupines throw their quills and wolves regularly chase people down and eat them.

The study took place in a hatchery and it was found that corn did not adversely affect the health of the trout.
If memory serves me correctly, the control group was fed pellets only, and the test group was fed corn only. There was no significant difference in mortality rates, though corn fed fish were slightly smaller. One would expect this as the pellets provided a more nutritionally balanced food source compared to corn.
