The world's largest blue magic shrimp, with a length of 30CM and a weight of 500g, is a freshwater shrimp from Florida, USA. It was named after its appearance when it was introduced? Blue magic shrimp? . The average blue magic shrimp has a body length of10-20cm and a weight of100-200g. The world's largest blue magic shrimp can reach 30 centimeters in length and 500 grams in weight, which is one kilogram, which is equivalent to three times the size of the crayfish we eat.
Although the blue magic shrimp is a mutant, it should not be considered as a rare animal. How much is a blue magic shrimp? Generally speaking, the price of Blue Devil Shrimp in the sky depends on the individual size. You can buy a seedling of about 2-3 cm in 30 yuan, and about 8 cm in 200 yuan. The bigger the Blue Devil Shrimp in the sky, the more expensive it is. The main reason to buy Blue Devil Shrimp in the sky is to look at the appearance.
Variations of the Blue Devil Shrimp Although the Blue Devil Shrimp comes from variations, there will be some variations in the growth process of the Blue Devil Shrimp for various reasons.
1, artificial sky
Artificial sky is an artificial sky shrimp which is purified and screened by artificial cultivation means for the original species of the sky shrimp. There are many kinds, such as blue artificial sky and original artificial sky. The color of this kind of shrimp is sky blue, which has the advantages of high ornamental value and low feeding difficulty. Australia's local pure artificial sky is Aubidus Pearl Sky, with uniform body color, dark blue, pearly white abdomen, shiny color and bright white. After molting, the body color gradually turns blue with time until it is painted with dark blue paint.
2, the original sky
The original sky is also called the original species of artificial sky shrimp, which is the original color of artificial sky shrimp, and can also be understood as wild sky shrimp or wild sky shrimp without gene purification. It is a subspecies of crayfish. This subspecies is characterized by a huge head, uncoordinated body proportions, aggressiveness, inability to raise artificially, and prone to broken pliers and even individual death due to fighting. The colors are mainly blue, green and brown, and the colors are not fixed. They change with the growing environment and may become different colors after molting each time.
3. Indonesian sky
Indonesian sky is a kind of artificial sky shrimp. Due to the influence of natural factors, the color of Indonesian sky turns to light blue. Because it is difficult to import Indonesian sky, it is hard to find photos, but compared with artificial sky, it is very light blue, and the joints of pincers are similar to the original sky.
How to raise blue magic shrimp The growth cycle of blue magic shrimp can reach sexual maturity in about 6 months, and the life span is 10- 15 years. Generally, the body length can reach 10- 15 cm in artificial breeding, but it is easy to reach 20 cm if the four key points of water temperature, water quality, feeding and water tank are well done.
1, water temperature
The feeding water temperature is 20℃-30℃, and the optimal water temperature is 24℃-26℃; Breeding water temperature: 26℃-28℃. The low water temperature affects the growth of shrimp, and the high water temperature is easy to lead to the failure and death of shrimp molting. The optimal water temperature is based on the conclusion that shrimp farmers keep trying, and the optimal water temperature is helpful to the molting and growth of shrimp.
2. Water quality
Shrimp can survive normally in the environment with PH value of 6.5 ~ 9, but it is best to breed in alkaline water. Because the water quality is too acidic, it is not conducive to molting, and it will also promote the formation of soft shells, which will bring harm to the normal life of shrimp, so the PH value should be controlled between 7.2 ~ 8. The hardness of water should be controlled between 17-25. Too low hardness will easily make shrimp shells soft, while too high hardness will easily lead to too hard shrimp shells and lead to molting failure.
Step 3: Feed
What the Blue Devil Shrimp eats is also a key point to pay attention to. Red worms and loach are cheap and affordable carnivorous feeds, while river shrimps and dried shrimps are high in protein and calcium, but their prices are relatively expensive. Shrimp is fed with red worms when it is young, and mixed with red worms and loach when it grows up. It is not recommended to pollute the water quality in bumper years.
4. Water tank
Don't feel wasted, use a big tank to raise, one tank can only raise one blue magic shrimp, and the two will definitely fight, and the space is large, which is very beneficial to the growth of blue magic shrimp. And the water tank must have a cover to prevent the blue magic shrimp from jumping out of the tank.
Precautions for the Shelling of Sky Blue Devil Shrimp When it is shelled, it is necessary to temper it during its growth. Before it is shelled, it is necessary to observe it carefully and make timely coping strategies to prevent it from being difficult to shell and death.
Whenever the blue devil crayfish in the sky is in the early stage of shelling, it will not eat. Then it will dig sand, and it will move the bottom sand to its own territory. After shelling, its body is fragile and most insecure, which shows that it is building a safe habitat for itself. The blue magic shrimp in the sky begins to shell from the head. The most obvious point is that there will be a crack between the head and the breastplate, which seems to be broken. It is white and can be seen inside, which shows that it has begun to shell.
First of all, these factors must be avoided before shelling: the first point is never to be deprived of oxygen. The basis of observation is that if your favorite shrimp paddles with its claws, it means that the oxygen content in the water is low, and the blue magic shrimp in the sky has been deprived of oxygen; The second point is to avoid being frightened and disturbed when hulling, which is generally the most vulnerable time for them and needs to be treated with caution; The third point is that the water quality is too good or too soft, which is not conducive to the shelling of the blue magic shrimp in the sky; The fourth point is that there is sufficient light, which is beneficial to the hard shell. The shelled shrimp is fragile, so external factors can be used to help it recover its previous majestic posture as soon as possible.
Generally, blue magic shrimp will shell once every few days, four or five centimeters usually once every two weeks, and it may not shell once every few months when it reaches more than ten centimeters.
The world's largest lobster, 1 1.33 kg, appeared in a seafood restaurant, owned by Steven? Jordan is used to this giant lobster. Because he can often buy 5 pounds, 7 pounds or even 10 pounds of lobster. But Jordan also admitted that this 23-pound lobster is really rare, and he has not seen such a big lobster for more than ten years. According to the size and weight of this lobster, it can be estimated that it is about 95 years old. Experts point out that lobsters in the deep sea usually live to about 100 years old.
