Primary text

The sale of worms (*didan*) used as bait on a fishing hook to catch fish is permissible due to the tangible benefit derived from them, placing them in the same legal category as fish.

Supporting text

An alternative view states that their sale is impermissible because their use is considered rare, equating them to objects without recognized benefit.
