How to tell if the stingray is in good condition, how to tell if the stingray is fresh or not

First, the stingray breeding environment.

To understand how to raise stingrays, you should first understand the water quality of their survival. The pH value that the stingray is suitable for.

On the left and right, it is a weak acid that is more neutral.

The second is the temperature, the water temperature of the tank for raising stingrays should be maintained at 26-28, but it should not be too high, because too high water temperature will make the residual food and excrement in the tank rot and malignant, and the deterioration of water quality will have a great impact on the health of stingrays. Therefore, it is necessary to regularly remove the residual bait, pump and replace the tank water, and at the same time, it is also necessary to do a good job of water quality testing regularly.

2. Stingray feeding.

How do you raise stingrays? Feeding is key. Stingray is a benthic fish, is a completely carnivorous animal, bait selection to sink is better, small fish and shrimp can be used as bait, generally large fish eat Zhu Wenjin, stream shrimp, loach and minced fish meat can also be used to feed.

It is worth noting that when feeding the brook shrimp, the spines on the head should be removed. Also, if the loach is larger, it is better to cut it into small pieces. Stingrays do not have the concept of fullness, and it is best to control the amount of food while observing during the feeding process.

3. Stingray diseases.

In general, freshwater stingray diseases are caused by water quality changes too quickly or worsening. Its common symptoms are: running point, mucosal hyperplasia on the body surface, upturned disc margin, gastrointestinal bacterial infection, and water mold.

Internal (external) parasites.

breeding bites, etc. When the stingray is not seriously ill, the old three can be used**, and if it is serious, it can be considered to use large white tablets.

Fourth, stingray polyculture.

By understanding the stingray breeding environment, feeding, and diseases, the problem of how to raise stingrays has also been solved to a large extent, and the polyculture of stingrays has also brought confusion to many aquarists.

There are many fish that can be polycultured with stingray, and medium and large fish in the middle and upper layers can be used. Most breeders will pair it with Arowana.

Sanjian, Brazilian, tiger fish, etc., or other tropical ornamental fish are polycultured together. It is important to note that it is necessary to choose individuals with suitable habits, and sometimes fish that can be polycultured with stingrays will also attack stingrays.

How to raise stingrays is not a problem, keep the water quality stable, feed diversified, and the stingrays are naturally healthy and strong.

The stingray, known as the manta ray, has a flat body, the whole is round or diamond-shaped, and the body is close to the bottom of the tank when swimming, and it is difficult to easily distinguish whether it is pregnant from the body surface, but if it is not clear whether it is pregnant, the time of production can not be determined, so there will be a certain risk to the birth of the baby stingray.

Due to the different strains of stingrays, the length of pregnancy is not the same, pearl stingray, black emperor, three-color and other strains from successful insemination to production, generally takes about three months, while black and white stingrays take nearly four months, of course, stingrays will also appear premature and postponed.

When the female stingray is successfully inseminated for a month, the belly will slowly protrude, and sometimes you will see similar to the human fetal movement, that is, when the female stingray is stationary, its belly will move up and down, left and right, and the usual movement of the stingray, of course, the fetal movement in the early stage of pregnancy is not very obvious, but with the growth of the female stingray's pregnancy time, the fetal movement will become more and more frequent, and the action will be larger, at this time the keeper will find as long as he pays a little attention to observation.

In short, the state of the stingray is that it can eat, pull and play, and will not appear in a bad state such as shortness of breath and curling.

You didn't say how big your fish tank is. The adult stingray will be very large, so Arowana and stingray players generally use special fish tanks, and the bigger the better! In particular, it should be noted that the width of the fish tank should not be less than 80cm, and there are about 4 stingrays in this fish tank!

If you're going to breed stingrays, then that's another story!

The edge of the disc of the wild species of black and white stingray does not have two small beads, which is the characteristic of the black and white crown; Space black and white refers to the appearance of some small beads around the large spots on the back of the body, which will increase more and more as they grow, which is also a manifestation that ordinary wild species do not have; Another type that is not mentioned is the "doughnut", which refers to the large spot on the back of the body as a hollow circle, shaped like an "o".

There is also the simultaneous set of these three performances is the latest improvement of the current black and white stingray, which is very rare in China at present, and is called the crown space donut black and white stingray.

First, stingrays exercise a lot and eat a lot. A healthy stingray will eat at any time, so be sure when choosing whether they are full of energy and willing to swim. When you sprinkle some food into the tank, do the stingrays respond positively, are they alert, and do they come to feed?

If the answer is yes, then this stingray is worth considering.

Second, carefully observe whether the stingray's body appearance is intact. Healthy stingrays have a slightly round body shape without any wounds, the body disc is full and smooth, no mucosal covering, body cartilage, the tail is intact and unbroken, the chest and waist bones do not surface, and the body disc has no erythema and bloodshot. There is no wound on the edge of the body, and when it is stationary, it is flat to the bottom or wall of the cylinder, and the disc surface is tightly adsorbed without buoyancy.

It has an intact gill foramen, a well-proportioned and slow respiration, a regular frequency, and normal relaxation of the thin upper respiratory membrane.

In addition, when choosing stingrays, you should go to a professional flower and bird market or an aquarium store, and do not buy them at roadside stalls. Before selecting stingrays, the keeper should prepare the aquarium and related equipment at home, raise the water in advance, and after selecting the right stingray, take it home and start breeding.

The simple summary is to be able to eat, pull, and play!

Catfish**:

Catfish is also called long-snouted catfish, commonly known as Jiangtuan, Feituo, Fat Kingfish, Huainan people are also known as Huai Kingfish. Because its snout is longer than that of the general fish, it is called the long-snouted fish. This species is mainly distributed in some sections of the main stream of the Yangtze River and the lower reaches of major tributaries, and is commonly found to be medium-sized fish.

It is distributed in the Liaohe River, Huai River, Yangtze River, Minjiang River to Pearl River and other river systems in eastern China and western North Korea, mainly in the Yangtze River water system. Due to the impact of environmental degradation, sharp decline of resources and artificial fishing, the resources of wild long-nosed bass in China have been sharply depleted, and the number of long-nosed bass has decreased sharply.

What does the squid taste like.

Hello, the eel is commonly known as the "water tiger", in addition to the northwest of China, from the north to the south of the sedan plain area of the water system. It is a large freshwater economic fish. The fish grows fast, is large, and has a delicious meat. I hope it can help you.

Stingray has high requirements for water temperature and water quality, and if it is not used to "trap water", it is easy to cause its death, and at the same time, the water temperature changes, and if the temperature difference is large, it will also make it die. Stingrays, also known as manta rays, are sharks that appeared in the Jurassic period of the Mesozoic Era (about 100 million years ago), and they have the habit of hiding in the sands of the seabed. <
