Do fish find food mainly by smell and touch, rather than by their eyes?

The role of a person's nostrils is to breathe. Fish also have nostrils, but its role is not to breathe, but to be an olfactory organ. Some fish have a nostril on each side of their head.

The reason for this is that it is easy to effortlessly let the water flow according to the nasal cavity when swinging against the water, and use the olfactory sac to identify and find the smelly food you like. This inspires anglers to look for areas with currents to hook, which are usually more abundant and of course easy to catch. At the same time, due to the currents, oxygen is abundant in these waters.

Fish love to play in the current, which is what people often say, "the water moves and the fish move." For example, if you turn on the faucet next to the tub and add water to the tub, if there is a small fish in the tub, the small fish will swim to the flooded area and appear very lively.

Many fish have very good eyesight. Therefore, they can find food based on their eyes and swallow it. Fish have eyes on both sides of the human body, but flounders and the like have both eyes on one side, but in any case, they are able to observe their surroundings on a large scale, one is to avoid the siege of nemesis, so that they can hide and escape, and the achievement is to find food.

There are actually four ways to find food in the water. The first is to rely on taste, and the taste organ of the fish is the chemical receptor of the fish, which allows the fish to perceive the taste of food from a long distance. For example, sharks are extremely sensitive to the smell of blood, and they can smell blood from a distance of 400 meters.

Another example is crucian carp, which can smell food up to 100 meters away.

Fish also use their taste buds to determine whether they want to eat or not. Fish are short-sighted, but they have a wide range of vision and are very sensitive to moving objects. Different fish have different differences in tone, appearance, and size, so they also need to cooperate with the sense of hearing.

In fact, there is also a problem, many people think that the sound will not harm the fish to find food, this is not right, in the noisy area, many fish will not go to find food. Therefore, when fishing, it is best not to make loud noises and scare away the fish.

Rather than relying on their eyes, fish actually have poor eyesight, and they mainly rely on their sense of smell and hearing to feed.

I think bait is used for both, but it uses the sense of smell first, because the fish have a very sensitive sense of smell.

Fish have a special sense of the lateral line, which allows them to perceive not only the sensation of water, but also hearing and touch. It has a certain role in various life processes such as fish feeding, migration, swarming, reproduction and defense. The lateral line is a sensory organ for fish to find bait, predators, and the interconnection between individuals of the same species. It is also their sensory organ to judge whether they are approaching various obstacles such as reefs and shore walls.

That's what it means.

It's like everything about you, with your senses.

Perceive you, understand you, communicate with you.

Both, but first of all, the sense of smell, the smell of fish is very sensitive, carp, crucian bream, etc., can be smelled within a few hundred meters. After finding the food through the sense of smell, the visual judgment is used to determine whether the food is edible, and then the lips touch lightly, and the sense of touch is used to determine whether to eat or not.

Fish have good hearing. Scientists have found that although many fish do not have long ears on the outside, they have specially designed sound receivers that transmit sound waves to the fluid-filled tubular structure in the inner ear. These tubes contain special fine hairs, called cilia, that transmit sound pulses through a series of complex mechanisms and chemical reactions to the fish's brain, where they are processed.

Fish mainly forage through sight and smell, and at the same time, they use their sense of smell to determine the food of their food. Secondly, fish will also make full use of their sense of taste when foraging to decide whether to eat or not. Fish are short-sighted, so they may sometimes use their sense of hearing, and the range of food they can feed is also related to the range of their senses.

Fish forage through different organs, but mainly rely on sight and smell, rely on vision to find food, and at the same time determine the location of the food through the sense of smell, and ultimately need to go through their own taste judgment, whether to swallow the food.

However, fish are short-sighted, but the range of vision is relatively wide, but fish are very sensitive to moving objects. Different fish species have different colors, shapes, sizes, and movements, so they may need to be accompanied by hearing.

The smell and taste senses of a fish are mainly concentrated on the head, which indicates that its range is around the top of the head, while the fish with the senses of smell and taste all over the body have a greater range of smell and taste, especially the food that is moving.

During the day, fish eat and perform other activities by the observation of the eyes, that is, by sight. At night, the fish's vision is very poor, so the night vision does not play a role, they only rely on the lateral line, smell, taste and touch of the body to navigate, find food and avoid danger, etc., these instincts are concentrated in the head of the fish.

Fish mainly rely on taste to find food, but sight definitely has a role, and if you want to think about fishing, it can be reflected, taste is very important!

The color of the submerged fishing beads does not have any taste, indicating that the sense of sight is more sensitive than the sense of smell.

Some fish use sight, but like sharks, they rely on their sense of smell.

Rely on vision to determine the position of things.

Fish mainly rely on their sense of smell to eat, because the eyes of fish are not elastic and cannot adjust the curvature, so most of the fish's eyesight is not very good, and the human myopia is relatively similar.

Fish's sense of smell is more developed, their nose is located on the top of their heads, and they can feel it when the water passes by.

Fish use their olfactory organs to sense the amount of amino acids in the water to obtain the quality of the water and the species of animals around it.

Fish not only have a sense of smell and sight, they also have a sense of taste and hearing. Although many people think that fish don't have ears, they actually have inner ears, which are hidden on the sides of their heads. However, their hearing range is relatively narrow, and only a few fish have a keen sense of hearing.

In addition to listening to sounds, the inner ears of fish also play a role in maintaining balance, allowing them to maintain balance when swimming. The taste of fish is also quite special, and it is not only distributed in the mouth, but also on the lips and body. This is so that the fish can feel the taste as soon as they get close to the food.

1 Fish usually rely on their sense of smell to find and find food. Vision is only an aid. 2 The eye surface of the fish is covered with a protective dura.

First of all, fish do not have eyelids and do not rub against this membrane by blinking; Secondly, this membrane is slightly keratinized and has a certain toughness. Water mixed with sediment doesn't hurt as much as you might think. In fact, it is the gills of fish that are most harmed by sediment-containing water.

Yes, because it knows that there is food, and it knows which foods to eat. Fish are also looking for their feelings, so that's it.

Of course, the senses of touch, smell and taste are present in fish, and many of the sensory organs and sensitivity of fish in water bodies are much stronger than those of humans, and of course they are limited to water.

Yes, the fish may not seem to react, but when you approach it or encounter danger, it will dodge, so it has a sense of touch, smell and taste.
