Carp bait can catch loach, because the bait has many versatility. Carp and shad are bottom omnivorous fish. No matter whether the bait is original flavor, pure fragrance, fishy smell or pure fishy smell, carp and shad will eat it, just in different ways. Carp mostly eat by swallowing, while shad mostly eat by scraping because of their mouth down. Pay a little attention to this. We usually use granular bait as carp bait, which may cause certain difficulties for local carp to eat and need to be softened or ground into powder in advance.
