Go to the local aquarium shop and get you some garlic juice. 100% fresh squeezed juice that has to be kept in another container to keep the smell down. Comes with a dropper tube for ease of use. This stuff is strong and a few drops go a long way. Where did you hear of the anise theory? My grandfather used to make his own fish attractant out of anise and olive oil with a smiggen of garlic. Claimed the fish loved it.
