As anglers, we want to return any fish that we catch in the best condition possible, and Propolis certainly helps to achieve that. This liquid is a natural product derived from bees, with antibiotic and antimicrobial properties, and is perfect for treating hook holds and existing mouth damage, or any other cuts, sores or abrasions that the fish may have on its body or fins. Propolis creates a waterproof seal over any wound, thus preventing bacteria from getting in and helping it to heal as quickly as possible. Propolis is easy to apply in a suitable amount for the area that needs treating, thanks to its dropper-style built-in nozzle, and once the affected area is covered, simply splash on a small amount of water to ensure that it sets before you return the fish.
