There are many kinds of crucian carp, and their feeding habits and fishing methods are different:
Carassius auratus in different water bodies have different feeding habits: Carassius auratus likes to eat bait in rivers, Carassius auratus likes fishy bait in lakes, and Carassius auratus eats both in still water ponds;
Different kinds of crucian carp have different feeding habits: white crucian carp likes plant bait and often bites off the bottom; Carassius auratus likes eating earthworm, maggot and other food bait and mollusk bait, and often bites the hook near the bottom of the water; The local crucian carp we often catch prefer rice grains, and most of them stick to the bottom for food.
What I said above is that in the absence of commercial bait, it is best to choose bait according to their eating habits. Now the bait on the market is generally made of potato flour, wheat flour and some fish attractants, which is good for crucian carp. If you want to fish, you can refer to the information:
