Amount of bait required?

[uke hunter]

Hey guys,

This will be my first trapping season and I am planning out my bait requirements for trapping this fall. I am going to be running 115 marten boxes,15 lynx cubbies and 15 weasel boxes (for which I will use grouse guts as I hear they work the best). Just wondering how many beavers you think I need in order to bait the marten boxes and lynx cubbies? Have been reading that a fist sized piece of beaver is about right for each martin box....don't know how many fists are in a beaver! Is that only meat or do you just chop the beaver up...both bones and meat?

Any thoughts would be appreciated!
