Wow that was way more complicated than it needed to be.
My advice for what it's worth.

DON'T use fish for bear bait. Bears like fresh fish.. The bears I have here in Alberta will not touch fish.. moves them off baits.
Second, Hang a beaver(natural food source) 7 ft high between two trees, that are 15 ft apart.
third, fill a 45 gallon barrel wit meat/beaver/pork (never whole baby pigs)scraps. cookies, donuts, oats, brown sugar, penut butter, what ever you can get a hold of that is tasty.
leave 2 inch lick holes in the barrel, maybe as big as 4inch, keeps the bears coming back.
if you dig a pit, or leave the bait easy for the bears to get at, they will fill up quick. The bears up here in Northern Aberta seem to run on a three day schedule(not all but most)if they eat lots at once. if you only let them niblle, not only will they come back every day, but the smaller ones will hang around giving you lots of fun viewing pleasure. they also act as early bear warnings, as they run off at the sign of bigger bears.

Make the holes in the barrel jagged to tear hair from the bears paws to indicate color phase.
Chaining is a good I dea, but not Necessary, as the bear will roll the barrel around, it helps to amuse them.

there is lots of good advice on this issue for you, pick what you think is useable, and creat your own methods.
