How do fish feed? What do fish feed on, and how do fish find food?

When foraging, fish should first rely on sight or smell to judge the food and positioning, then rely on smell to perceive the smell of food, and then decide whether to eat, and finally rely on taste perception to decide whether to swallow food. Vision: Fish use vision to spot food when they are foraging**.

Different fish species are sensitive to different colors, shapes, sizes, and movements. Fish like active food, but the distance between animals and animals that are also myopic is within a few meters to more than ten meters. Sense of smell:

Fish can smell the smell of substances in the water, including food, companions or predators, etc., and during the day, fish have developed vision, and the sense of sight and smell complement each other. Taste: Fish are more sensitive to sweetness, 512 times stronger than normal people's taste, so other flavors should not be used as bait after making bait.

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.

The time it takes for fish to come out to feed varies depending on the species of fish and the environment in which they live. In general, fish come out to feed during the day and at night, but the specific time and behavior habits vary depending on the species of fish and the environment in which they live. Here are some common scenarios:

Carnivorous fish: Carnivorous fish generally come out to feed at dusk and at night, when there are more other tactile fish in the water, which is conducive to their hunting.

Freshwater fish: Freshwater fish tend to come out in the morning and evening to feed, when the water temperature is lower and the oxygen content in the water is higher, which is good for them to breathe and digest.

Marine fish: Marine fish generally come out to feed when the tide is changing, because at this time, planktonic finger-raising organisms and benthic organisms will gather on the surface of the water or the bottom of the sea, which is conducive to their foraging.

In summary, the time when fish come out to feed varies depending on the species of fish and the environment in which they live, and needs to be analyzed on a case-by-case basis.

Fish feed in a variety of ways, but most of them use the following two ways to feed their fingers and:

1. Inhalation: This type of fish is generally relatively peaceful and docile, and most of them are omnivorous fish. They usually use breathing movements to feed on the surface of the water, that is, they open their mouths to let the water and the bait enter the mouth at the same time, and then let the water flow out from under the gill cover to feed the bait.

Fish such as carp and grass carp feed in this way.

2. Predation method: This kind of fish is generally a fierce carnivorous fish, aggressive, with strong swimming ability, sharp and developed teeth, and sensitive movements. They survive by preying on a variety of small animals that live in the water, not only small animals in the water, but also smaller fish, biting and chewing on food.

Our country is a vast country, and in most of the freshwater, many fish schools are omnivorous. Common omnivorous fish groups include crucian carp, carp, silver carp, bighead carp, white minnow, tilapia, horsemouth, peach fish, loach, etc. They prey on zooplankton, small mollusks, and also eat some plant debris, algae, and humus.

However, the feeding habits of some species change depending on the outside world.

1 Crucian carp and carp are very common fish in our daily life, and if you carefully observe their bait eating habits, some rules are also easy to grasp. In early winter, early spring and late autumn, when the temperature is not high, they mainly grow on high-protein meat foods. If you are fishing for crucian carp or carp during these hours, you need to use meat bait as the main bait.

In late spring, early summer and early autumn, crucian carp and carp live mainly on the detritus of higher plants, and anglers can directly use plants to make fish nests to lure fish. In the summer, when fishing for carp or crucian carp, anglers can also hang bait directly on the hook to fish, so that fishing can also be very rewarding.

2 In the freshwater fish group, silver carp and bighead carp are a special type of fish, they will filter food with their gills before swallowing bait when they eat. Silver carp and bighead carp love to hunt plankton and phytoplankton. In spring and autumn, they also eat large amounts of humus and plant detritus to fill their stomachs.

This habit of eating bait makes many anglers deliberately make the bait sour and smelly when fishing for silver carp in Taiwan.

3. The white minnow, this kind of fish is a typical omnivorous fish, they eat everything, when the angler goes to the table to fish, you will find that the bait it eats, and the small insects with a heavy fishy smell they also eat, and the frequency of fishing, the fishy insect bait is easier to bite the hook than the bait.
