Out cottage area was infested with them for a few years....
We had a tank that was 3.5'x5' and about 3' deep for minnows... One night I went fishing and put my catch of 4 walleye in the tank LIVE to clean in the morning...
When I got up they were all gone and there were little mink tracks all over the tank... One of the walleye was pushing 5lbs... Couldn't believe they could catch and kill a fish that big...
Another time I was dropping off my buddy on shore cause he has to go to work... He made 2 trips to his truck... First for tackle and second for fish... When he returned for the fish his entire stringer was bouncing across the rocks with a mink leading the way... Lol
