What s the deal with a lot of water in a fish s belly?

The fish's mouth opens and closes.

Non-stop, but not necessarily drinking water. Ichthyologists tell us that this is to speed up the flow of water through its gills so that it can absorb the oxygen in the water and release carbon dioxide from the body.

Fish that live in freshwater do not drink water for life; Saltwater fish, on the other hand, who live in the sea, drink water frequently.

Why is this so? May as well start with osmotic pressure.

Speaking of. The osmotic pressure is determined by the substance dissolved in the water. The more material dissolved in water, the higher its osmotic pressure.

Whereas, water seeps from a solution with low osmolarity to a solution with high osmolarity. Pure fresh water, osmotic pressure is equal to "0". Freshwater fish have a higher osmotic pressure than the surrounding freshwater, and freshwater seeps into the fish from the outside of the fish.

Therefore, freshwater fish not only do not have to drink water, but also try to eliminate the excess water that seeps into the body, otherwise they will be swelled to death by the water. The saltwater fish living in the sea is different, its meat Ji Ji Ji Ji chewing and killing ghosts and looking for Handmo and other tissues are light, the osmotic pressure is lower than the surrounding dissolved salts of seawater, the water in its body is constantly seeping out of the body, so it is necessary to drink water often to replenish the water lost in the body. But there are also a few fish in the sea, such as sharks, that do not have to drink water because it retains urea in the blood.

Maintain the osmotic pressure of body fluids higher than the osmotic pressure of seawater.

The enlargement of the fish's belly should be overeating, bacterial enteritis or ascites. The main cases of fish belly enlargement are as follows: 1. Due to too frequent feeding by fish food and feeding people, the fish stomach becomes larger only after eating; 2. The ascites of fish will also become larger due to the unclean water; 3. Eating unclean food and often eating but not digesting it will lead to bacterial infection of the intestines, causing the fish belly to become larger;

That is, when selling fish, the belly is filled with water, otherwise the fish swim in the water, even if the fish belly has water, there will not be too much.

It feels like a routine, maybe the vendors are fooling customers with more catties and two, of course, the fish itself has some water.

This shows that the sun of drinking water before the fish eats can also be said to be the economic improvement caused by the consumer merchants pouring water into the fish belly.

Hello netizens, you must have met a black-hearted merchant who poured water into the fish. Then the merchant has to report it.

It was clear that the fish had drowned and had water in its belly.

Many times, when I see a fish with a big belly, I immediately think that the fish has a "child". In fact, this is very easy to distinguish, fish will not "give birth" at any time, and will only have when the temperature is suitable. Generally warm seasons such as.

March and April are the usual times for fish to "give birth", and in colder areas it is delayed. Of course, it is necessary to cooperate with other conditions to judge, to see if there are male fish "chasing", etc., if they are all satisfied, it is necessary to be ready for "production", such as preparing aquatic plants, and feeding in fish tanks.

The second is that there are too many fish. Don't always worry about the fish not being able to eat enough, they can only eat a little bit at a time, so feed in small amounts several times, not more than three times a day. If you know how much to feed and how long you want to feed each time, the cuties will grow up healthy.

At this time, reduce the amount of food to see if the belly of the fish is smaller, and if so, then rule out other conditions. Pay attention to the changes in the body size of the fish and adjust the feeding method in time.

The third question is worrying - is the fish sick? This situation is actually quite common. If the above two conditions are ruled out, check whether the "poop" of the fish is different from usual, such as whether the color has turned white?

At this point, it is almost certain that the fish is "sick". Don't be in a hurry at this time, what causes the fish to get sick is "enteritis", and then there is water in the stomach, and it can't be discharged, so the stomach is propped up.

At this time, there are two things to do, one is to check whether the food that has been fed recently has deteriorated, and check whether the water change has been treated in advance, such as basking in the sun for a period of time, checking the cleanliness of the fish tank, and checking the aquatic plants. Pay attention to the constant water temperature, which can cause the fish to get sick due to their discomfort. The second is to use medicine, you can go to some professional stores to buy some, one is in water, the other is mixed in fish feed.

Many people have the habit of raising fish, whether it is raising special ornamental fish, or breeding crucian carp and other edible fish, we must pay attention to the water quality and other conditions, and some abnormal symptoms of fish should also be noted. Ascites is a disease that fish are prone to, and the later it is detected, the more likely it is to die, so it is best to detect it in the first place. Now, let's learn about it with me!

How to have ascites in the belly of fish**?

1. Change the water. Poor water quality does not help its recovery and may even deteriorate. In general, fish farming should be changed once a week. If the water gets muddy quickly, it's basically every three or four days.

2. If it is polyculture, it is best to isolate the sick fish to avoid infecting healthy fish. But be sure to choose good water. If the water quality is not good, there will be a stress response after isolation, coupled with your own illness, there is a high chance that the fish will die.

3. Drugs**, generally use large white tablets or norfloxacin, and take a medicinal bath after making a solution. Put the sick fish in the wild or soak it for a while, then take it out and put it back in its place.

Why do fish have bulging bellies?

1. The characteristics of some fish are like this, for example, some goldfish, the bigger the belly, the more obvious the characteristics.

2. During the breeding period, the abdomen of the fish is distended. It can be observed to see if there are fetal spots, and only for females.

3. In the later stage of enteritis, there is ascites, which is a difficult disease.

4. The fish is overwhelmed. If you don't pay attention to feeding, there is a lot of bait left in the water body, causing it to keep eating and eating to support its stomach.

Heat the rod 25w with how big a fish tank

The 25W heating rod is not suitable for large fish tanks, it can only be used for the smallest size fish tanks with a volume of less than 12 liters. If you use a large fish tank, the heating time will become very long and it will consume more electricity. It should be noted that the power of the heating rod can be larger, so that the heating speed is faster, and it will be turned off after the target temperature is changed early, so there is no need to worry about the continuous heating will affect the healthy fish.

The enlargement of the fish's belly may be pregnant, with a baby in the belly, or it may be sick. If it is the former, then it needs to be paid attention to, and the fish should be well managed after production, so that the survival rate will be high. If it's the latter, it may be a gastrointestinal problem, and most of these messy problems actually have only one reason, that is, feeding!

Don't feed fish too often, feeding too much fish will easily cause a series of gastrointestinal diseases.

If you are not pregnant, you are more likely to be sick.

Generally, if the koi has a swollen belly, there are generally four reasons, the first reason is because of eating more, resulting in a bulging belly, you should pay attention to the amount of feeding, some koi may not know whether they are full and have been eating.

The second reason is that the fish is sick and causes water in the stomach, which is generally caused by food, eating unclean fish food or spoiled and moldy fish food, koi fish are very fragile and difficult to resist bacterial invasion.

Pregnant or with fluid in the stomach

You didn't make it clear, what kind of fish do you raise?

It's very likely that there are fish larvae in it.

Oh, you're talking about a small tropical fish.

It should be Mickey, it is normal for this fish to have a big belly, it is obvious that it eats a little more, it may also be pregnant before coming to you, you observe its behavior, if there is nothing abnormal, it means that your fish is normal, don't worry, look at its swimming posture, breathing rate, feeding behavior, it should be fine, you observe it.

The belly of the fish becomes very large, probably enteritis.

Formation of enteritis: long-term use of spoiled or expired food, or large feeding of puffed food that has not been soaked in warm water. Caused by large amounts of fish eating aged green moss, fermented and spoiled fish feces, etc.

Enteritis medication: yellow powder. The yellow flour can be ground and made into small grains with rice grains or steamed buns, (the size is determined according to the fish body, and small dots are preferred) to wrap the yellow flour inside. Give it to the fish, and the fish will not refuse to eat. The effect is obvious. The effect was seen in 7 days, and the 15th was cured.

The enlargement of the fish's belly should be overeating, bacterial enteritis or ascites.

There are several main cases when the belly of the fish becomes larger:

1. Due to the frequent feeding of fish food and feeding people, the belly of the fish becomes bigger only after eating;

2. The ascites of fish will also become larger due to the unclean water;

3. Eating unclean food and often eating but not digesting it will lead to bacterial infection of the intestines, causing the fish belly to become larger;

Whether it's a big one, where is enteritis, just take some medicine. If you have a big belly when you finish eating, it means that you have fed too much, and generally ornamental fish can be fed 1 or 2 times a day, once in the morning and once in the evening.

Obviously, he fed too much, once a day, 5 to 8 grains at a time, and he couldn't see the effect if he had to digest it for a day.

The enlargement of the fish's belly should be overeating, bacterial enteritis or ascites.

There are several main cases when the belly of the fish becomes larger:

1. Due to the frequent feeding of fish food and feeding people, the belly of the fish becomes bigger only after eating;

2. The ascites of fish will also become larger due to the unclean water;

3. Eating unclean food and often eating but not digesting it will lead to bacterial infection of the intestines, causing the fish belly to become larger;

1.It still depends on the habits of feeding, if you feed a lot and the fish is in a normal state, it may be fat.

2.If you feed normally, other fish are normal, only this fish has a big belly, you should observe the state of this fish, whether it eats actively, whether it is anorexic to the bottom wall of the tank, and whether the fish's poop is slender and has a long drag. That's probably intestinal phlegm.

Intestinal phlegm is a recurring condition, which can be caused by overfeeding at the bottom of the water temperature.

3.It may also be a difficult disease to deal with, such as parasites or fluid in the stomach.

4.Pregnant.

If it's fat, it doesn't matter.

Intestinal phlegm can be observed by fasting for two days. Then soak the fish in garlic juice, dry it and feed it for a period of time.

Other diseases need to be treated with insecticide and sterilization. Let's look for a specific question.

I also have some experience, I wish you a good day**.
