they should not be fed people food becuase of the salt and other spices. fresh and uncooked or live and WHOLE remember! predatory fish along with all other predatory animals need to eat whole prey. they get needed nutrients from the shell, bones, guts, head, etc...etc. or feed a high quality pellet, brand name, not the bulk trout pellets($1.00 for 5lbs) thats junk and not carefully balanced nutrition.
