Why do fish starve and not die? Why do fish starve and not die? Can they go without eating?

In rural areas, farmers usually use their idle tanks to grow lotus roots or raise small crucian carp that they have caught.

As we all know, crucian carp is an omnivorous fish, and its diet includes: earthworms, maggots, mosquito larvae, small insects, stems and leaves of aquatic plants, petals that fall into the water, rice, rice, wheat, etc., etc., everything that can be eaten can be eaten. <>

Farmers living in rural areas and friends who love fishing know that in spring and summer, walking on the edge of the ditch river in the countryside, they will always hear the sound of "horn coo, horn coo" from the aquatic plants on the water surface, that is, the crucian carp is floating on the water surface to eat the young stems and leaves of aquatic plants.

And how tenacious the vitality of crucian carp is, I'm afraid not too many people know! <>

Suffice it to say, crucian carp cannot survive except in water containing highly toxic chemicals! For the rest, wherever there is water, there will almost always be crucian carp!

Why?

On the side of the Longmian Avenue subway station in Jiangning District, Nanjing, there is a small stinky water river, once after the subway arrives at the station, when it is convenient to go to the stinky ditch, I actually found that there is a large group of small crucian carp floating in the small stinky ditch with their heads inhaling oxygen! <>

There is also the door of my house, in the 2,000 years due to the soil to make the Qinhuai River embankment, picked out a small pond with only about half of the land, at that time was also raised by people for a few years of fish, but later it was covered by the weeds and peanuts, and the longer it grows, the thicker it gets, even if a person stands on it, it will not sink! And it emits a strong stench, and it stands to reason that there will be no fish except for some yellow eels in it!

But one day I was under the wild moon flowers, and I actually saw some small crucian carp floating their heads! At that time, I really sighed that in such stinking waters, no food and no oxygen, it can still survive, which shows that the vitality of crucian carp is extremely tenacious!

So about the question asked by the subject, in the rural water tank, it is common to see farmed crucian carp, never fed, but the fish will not starve to death?

1. Farmers living in rural areas know that in the spring, summer and autumn of the countryside, all the utensils placed outside, as long as there is water, there will be a lot of mosquito larvae swimming in the water, and crucian carp is an omnivorous fish, so mosquito larvae just become their snacks.

Second, in the countryside, there are many kinds of insects in the summer. Such as: glow fireflies, seven-star ladybugs, flying ants, moths, etc., as long as they fall in the water of the tank, they will become a crucian carp delicacy.

Third, when the water in the tank is stored for a long time, because it is a pool of stagnant water, it will slowly grow baths, such as moss, crucian carp can eat moss to satisfy hunger without starving to death.

Fourth, when farmers take water from natural waters to raise crucian carp, there are many microorganisms and micro-animals in natural waters, so they also fill the stomach of crucian carp, even if they are not fed, crucian carp will not starve to death!

Because fish are cold-blooded animals, their energy requirements are not very high. In addition, there are microorganisms and algae in the water, so the fish will not starve to death if they are not fed.

Because it can drink water, it is an aquatic animal that lives in an environment full of water, and can eat aquatic plants and the like to sustain itself, so it does not die.

Because the fish are quite resistant to hunger, they will not starve to death even if they are not fed for a long time, and because there are algae plants in the tank to provide nutrients to the fish.

Because there are a lot of microorganisms and small algae in the water, they are all food for fish and can replenish nutrients.

Because fish live in the water and feed on plankton and aquatic plants in the water.

Because the stomachs of fish are small, they do not die of hunger, and they can eat enough microorganisms in the water. Fish generally eat as much as they want, so they are easy to die.

Friends who have fish at home should understand that they should not feed the fish too much, otherwise the fish is very easy to "die", but sometimes they go to other provinces for vacation or go out, and they will not starve to death if they return home or fish or seriously. Why, then, do fish die of starvation rather than starvation?

1.Since fish are cold-blooded animals.

Cold-blooded animals are characterized by being very hungry. For example, snakes are also cold-blooded animals, and snakes only need to eat a full meal to carry them for many months without eating. This is due to the basal body temperature of cold-blooded animals.

It will change with the change of temperature, and the cold-blooded animal consumes very little kinetic energy, koi.

Except for it, as long as you ensure that you can go without eating for a long time under the water environment treatment.

2.Due to the common combination of fish diet.

Everything in the water that has nutritional value can be turned into fish food, such as larvae that fall in the water, and even germs, which can be eaten by fish. In addition, the most important thing is that fish can be self-reliant, because the fish feces contain nitrogen, which can promote the growth and development of algae plants and microorganisms in the water, and algae plants are also one of the food products of fish.

1.The ingredients are surging and the fish is dead.

Most of the bait we feed to the fish is the bait that will absorb moisture, after we cast this bait, the bait will not immediately absorb moisture and surge, until the fish eat this bait, the bait will rise to the cost of many times the volume, so if you accidentally feed too much, it is very easy to kill the fish.

2.Rotten and spoiled ingredients, fish get sick.

This is also very important for the reason, due to the bait promotion too much, the fish leftover part will sink to the water, with the change of time, this bait will use oxygen in the dissolution link, and cause a lot of harmful substances, if not immediately removed and the fish tank water change, it will cause the fish to lack oxygen or poisoned and die, and then give people the feeling of death. Therefore, at the time of feeding, we should pay attention to the standard of Ning Shao, do not have to feed the fish every day, and maintain the number of feeding 2-3 times a week, and do not have to promote too much each time.

This is because fish are very adaptable, very tenacious, and can get a certain amount of food in the ocean, so they will not starve to death. They should not go without food.

This is because the stomach of the fish is very small, and it can usually live by eating microorganisms in the water, and it is not possible to eat as much as you want to feed the fish, so it may usually die.

Because the stomach of fish is relatively small, they can't eat too much food, and any little microorganism can be full; They can go without eating.

The stomach of the fish itself is relatively small, the fish is a cold-blooded animal and its own consumption is not large, and the fish can not eat for a long time after being full.

Because fish have very small stomachs and can eat microorganisms in the water, they will not starve to death, and they cannot go without eating.

One of the characteristics of cold-blooded animals is hunger. For example, snakes are cold-blooded animals. As long as they eat a big meal, they can go months without eating Dongchang.

This is because the body temperature of cold-blooded animals changes with the ambient temperature. Cold-blooded animals consume very little energy, and goldfish are no exception. As long as you stay in the water, you can continue to go without eating for a long time.

Everything in the water can be used as food for fish, such as eggs and even bacteria that fall into the water, which can be eaten by fish. In addition, the most important thing is that the fish can be self-sufficient, as the fish excrement contains nitrogen, which promotes algae in the water.

Algae is also one of the foods for fish**. The fish in the tank can live forever because there is energy in the water.

Although the tank is small, it actually contains a lot of microorganisms, some of which belong to phytoplankton and can be photosynthesized.

Generate energy. The phytoplankton are very small, but also very numerous. When the fish breathes in the tank, its gills filter some phytoplankton and plankton.

As energy**. If there are lotus flowers, water lilies in the tank.

and other plants, then the roots of the plant can also be used as the energy of the fish**.

Sometimes, the fish can eat in the tank because the water in the tank is still water. Insects like mosquitoes and flies to lay eggs in still water.

The eggs of these insects are the protein of the fish**. However, not all fish live in a tank for a long time. Different fish have different energy needs, and some feed on other small fish, such as the black fish. They like to attack other fish and feed on small fish.

Adapting to the tank environment are mild herbivorous fish, such as crucian carp. However, it should also be noted that although some fish can survive in the tank for a period of time, there should not be too many individuals in the tank. If you want to breed better, it is best to feed regularly.

After all, the energy in the tank is limited. In fact, as long as the fish in the tank are not particularly farmed, they generally do not grow very large, and their body size is much smaller than that of the fish in the river.

I'm sure many people who have some knowledge of fish have heard that fish don't starve to death? In the past, when tap water was not widely available, many people had large water tanks at home to store water. The water tank is relatively large, and it is often not used up, and sometimes the water in the tank will become turbid and green.

Some people put a crucian carp in the tank at home, and the water in the tank is usually clearer and less easy to turn green. Because it is drinking water, it will definitely not feed the fish food, but the fish will not die, but they are relatively thin, so there is a saying that the fish will not die of hunger. Scatter or.

The fish will definitely die of old age. All things in the world, birth, old age, sickness and death, are inevitable objective laws and cannot be resisted.

If fish are raised in a natural aquatic environment such as ponds, the fish are not easy to starve to death if they are not fed because they are able to eat microorganisms and plankton in the water. If you keep fish in a tank, the fish will only live for about twenty days without feeding. Not feeding the fish for a long time will affect the growth of the fish, so it is recommended to feed the fish on time every day.

Whether the fish will starve to death if they are not fed depends on the water environment, the fish do not have a high demand for food, the microorganisms and plankton in the water are their food, if the owner can provide a water environment close to the natural ecology, such as a pond, the fish will not starve to death if they are not fed for a long time.

If you keep fish in a home tank, the fish will starve to death if they are not fed for a long time. In the case of not feeding, the fish generally only live for more than twenty days, but it is not recommended that the owner go unfed for so long.

Because although fish are not easy to starve to death, they will not grow their bodies if they do not eat for a long time, which will affect their appearance. Generally, depending on the size of the fish, the amount of feeding is 1 3 times a day.

Because fish are cold-blooded animals and consume less energy, they cannot starve to death. As for the death, it is mostly due to overfeeding, which causes the food to enter the belly of the fish and expand, resulting in the death of the fish.

Because fish are not very demanding on food. He didn't have a place to stock up on a lot of food. So if you eat too much, it will be strangled.
