Abstract: The present invention relates to an artificial bait for marine animals, comprising cell-free hemolymph of a horseshoe crab. The cell-free hemolymph of the horseshoe crab, which is the byproduct from the manufacture of Limulus Amebocyte Lysate (LAL), is an excellent attractant to be used in artificial baits for marine animals. The baits according to the invention attract the target marine animals better than the horseshoe crab itself. Further, the baits of the invention seem to attract non-target game less than the target game. The present invention also relates to a method of preparing a bait comprising cell-free hemolymph of a horseshoe crab, and a method of attracting marine animals.
