How do fish find food in water, and what do fish rely on to find food?

Summary. Hello, dear. Glad to answer for you :

How Water Fish Discover Food The reply is as follows: The answer is: Water fish find food through their sense of smell.

The sense of smell is the most developed sense of fish, of course, this refers to normal wild fish, and many farmed fish do not have such a developed sense of smell. Generally, at night, fish can only rely on their sense of smell to feed, which tells us that when fishing at night, the taste of bait is more important, especially for fish with extremely degraded vision such as catfish, and the sense of smell is the main means of foraging. It should be noted here that different fish like different smells are different, it is often said that carp likes sweet fragrance, and silver carp likes sour smell, so for different fish, it is necessary to choose different bait flavor types.

The answer is: water fish discover their food through their sense of smell. The sense of smell is the most developed sense of the Lingwei fish, of course, this refers to normal wild fish, and many farmed fish have a less developed sense of smell.

Generally, at night, fish can only rely on their sense of smell to feed, which tells us that when fishing at night, the taste of bait is more important, especially for fish with extremely degraded vision such as catfish, and the sense of smell is the main means of foraging. The lack of ruler branches that need to be explained here is that different fish like different smells, and it is often said that carp likes sweet fragrance, and silver carp likes to wear oak and sour smell, so for different fish, different bait flavor types should be chosen.

Kiss. Fish, the oldest vertebrate. Some offspring of crosses with different chromosome numbers are still fertile.

They inhabit almost every aquatic environment on Earth, from freshwater lakes and rivers to saltwater seas and oceans. Fishes are divided into two general classes: jawless and jawed, jawless general class includes round mouth class, armor fish class, jaw general class includes shield fish class, cartilaginous fish class, radiated fin fish class, most fish are living in water all year round, breathe with gills, use fins to assist the balance and movement of the body before hunger and movement of ectothermic vertebrates, there are also like African lungfish, mudskipper, climbing perch can survive on land for a long time, and black fish, yellow eel, gar rely on a single swim bladder to breathe, although most fish are cold-blooded, But many sharks and tuna are semi-homeothermic, while moonfish are homeothermic.

There are more than 36,000 species of living fish in the world, accounting for most of the named vertebrates, and new species of fish are constantly being discovered, with an average of about 150 species per year, and more than 1,500 species should have increased in more than 10 years.

The first is hearing.

We often say hertz to summarize the hearing ability of animals, for example, the human ear can hear the frequency of sound waves from 20Hz to 20000Hz, while the dog can hear the sound wave frequency from 15 Hz to 50000Hz, which means that dogs can hear infrasound waves (less than 20 Hz) and ultrasound (higher than 20,000 Hz) that we humans cannot hear.

The second is the sense of smell.

It is obviously not enough to rely on hearing alone, because some land debris will also be blown into the water by the wind, thus producing sound, so that the fish are likely to run over and be happy in vain, and this is where the role of smell is reflected.

Finally, there is the lateral line.

When we see the side of the fish, we see a line (some obvious, some not obvious) that extends from the gills to the tail in the middle of the body side, which is actually the fishy line, also known as the fishy line. When handling fish, in order to alleviate its fishy smell, many people are accustomed to use a knife to make a cut behind the gills of the fish, then find the side line (a thin white round line) and pull it out.

The lateral line is a unique organ of fish and amphibians, it belongs to a kind of **receptor, and it is the most sensitive to Zheng advanced one, although it looks like a simple linear body, but in fact it has two important components: Lauren's kettle bridge and nerve mound.

Hello pro Fish eat food in the water, mainly relying on the structure of the mouth and the help of the current.

First, the mouth of fish usually has structures such as gill arches and gill rakers that are used to catch and ingest food. Their mouths are large and flexible, opening and closing in order to swallow food of different sizes.

Second, fish often use currents to help with predation. When fish get close to their food, they quickly open their mouths, creating an area of negative pressure that allows the surrounding water and food to be sucked into their mouths. The fish then quickly closes its mouth, draining the water and leaving the food in its mouth.

In addition, some fish also use the teeth or tongue in the mouth to process food. They can chew, tear, or filter food to accommodate different types of diets.

In general, fish catch and process food by opening their mouths and using the current and mouth structure. Their adaptability in the water allows them to efficiently obtain the nutrients they need.

I think you all know a lot about the eating habits of the freshwater fish we catch. But do you know about the feeding preferences of some omnivorous fish species in different waters? When we come to an unfamiliar water, we first need to have the fish species present in the water, as well as the density, body size, etc.

Secondly, we should be good at observing, what vegetation is in and around the waters, and there are no small fish, small shrimps, snails, and shellfish that fish love to eat in the waters. I don't know if you have the habit of shaving fish yourself. I have a habit of dissecting fish guts for the purpose of better understanding different waters, different seasons.

Different times. and what fish of different sizes like to eat. So as to "prescribe the right medicine".

Let me talk about my experience with carp feeders. 1.reservoirs, when the water rises, most of the fish caught can find a large amount of grass seeds from the intestines.

At this time, it is better to choose the fishing spot around the flooded meadow. 2.Reed stall Carp has a very mixed diet and eats almost anything.

The feeding habits of carp vary greatly depending on their body type. Less than 2 kg can often be found in the intestines: dark green cut very delicate and incomplete food.

It shows that it mainly eats algae. Dark-brown or black food is coarse and it is likely to eat some decaying plants at the bottom of the water. This is common in spring and in waters, where food is scarce.

More than 2 kg can often be found in the intestines: small fish bones and small snail fragments, big fish eat small fish. For large fish, it is better to use bait with fishmeal and snails.

There is also a situation where the big fish are not eaten after entering the nest. Tossing and turning in the nest for a long time before he would eat the food on the hook. The fish that come up like this should be carefully observed when they go home, if there is a large amount of bait.

There are two reasons for this. 1. In the case of the bait and the bait all the time, it is likely that the nest is too heavy. 2. If the bait is different from the bait, it means that the fish prefer to eat the bait.
