Yep, they do eat fish, and they do eat some types of fruit and nuts. Sort of like grizzlies, I must say. Except most of the time, grizzlies prefer to eat grass, berries, and nuts, whilst wolves, only eat them a small percentage of the time, either while prey isn't available or if they need to eat. I've seen wolves eat grass, just like dogs, because it is a "filler" to help vomit up the food they do not need.
But Blue, don't you require a permit for where you live? Unless, of course, your in a state that allows it, or you live out of the U.S.
As a mammalogist I have done much research on wolves, and many other animals, and, in fact, wolves are never tame animals. No wild or domestic animal is exactly "tame", but they are owned. I've seen reports on people getting bitten and stomped by many animals that they thought were tame, including feral dogs and cats (i.e. lions, tigers, dingos, wolves, foxes), because they were not treated the correct way.
So, I highly hope you are professional, but whatever rocks your boat is fine. I am not trying to interfere with you or your family's tradition, I am just stating some of my research. Good luck and hopefully you do well. C:
