NOTE:

  1. You can bait these traps in any manner. However, the trap must have all the features noted above.
  2. There is no exception for traps set under ice: traps set under ice, whether baited or not, must have all of the design features noted above.
  3. There is no tension requirement. However, DEC research showed that 8 to 12 oz. of tension works best for protecting otter and catching beaver.
