How do fish feed?

Fish first rely on vision or smell to determine the source and location of food, then rely on smell to perceive the smell of food, then decide whether to eat, and finally rely on taste to decide whether to swallow food.

Vision: fish use vision to find food sources when foraging. Different fish have different sensitivities to different colors, shapes, sizes and activities. Fish like active food, but the distance between them and animals with the same myopia is within a few meters to more than ten meters.

? Smell: substances that fish can smell in water, including food, companions or enemies. During the day, fish have developed vision, and vision and smell complement each other.

? Taste: Fish is sensitive to sweetness, which is 5 12 times stronger than normal people's taste, so it seems that other tastes are not suitable for bait after bait is made.
