At the turn of spring and summer, it is a good time to eat crayfish, a couple is attracted by the mellow fragrance on the head of the crayfish, they accidentally touch the head of the crayfish, and the "yellow" of the crayfish accidentally falls on the table.
A couple questioned whether the "yellow" on the head of the crayfish was shrimp yellow or shrimp, some people said it was shrimp yellow, but others said it was shrimp, and there was no agreement.
So what exactly is the yellow color on this crayfish's head?
Cognition about crayfish yellow.
As a delicacy, crayfish has been loved by everyone, and for the "yellow" problem of small caries lobster, you might as well start with the crayfish itself.
Why is crayfish called lobster, it generally grows in rivers and lakes and has a golden shell.
The growth of crayfish needs the soil environment, and the female shrimp needs to find a suitable burrow for production when they give birth, while the male shrimp plays the role of guarding and patrolling to prevent other small animals from disturbing the situation.
The crayfish born from the female shrimp are called baby lobsters, and they can swim in the water surface in less than half a year.
Crayfish has a very high nutritional value, rich in protein and trace elements, as well as high nutritional value, and rich in minerals.
What exactly is the "yellow" on the head of a crayfish?
The color of crayfish is golden yellow, but what exactly is the "yellow" on the head of crayfish?
Less than 10 days after birth, crayfish are able to store overwintering substances in their bodies, and at this time crayfish will have something similar to eggs in their bodies.
That's when it's called lobster roe.
This is because the menstrual period of crayfish is in the spring, at this time the water quality in the rivers and lakes is relatively cool, if the small fish and shrimp are spawning at this time, it is easy to cause the small fish and shrimp to die because they can't stand the cold, so the crayfish only use fertilized eggs to spawn and conceive lobster babies.
When crayfish are spawning, if there is an excess of sperm in the body, it will be stored in the body, and if the storage is excessive, sperm hoarding will occur, resulting in the female shrimp spawning in the same place, which can easily lead to a decrease in oxygen and poor water quality.
When the temperature drops dramatically, putrefactive substances grow, and when they come into contact with sperm, they become immature.
Therefore, the crayfish will soak the sperm into the yellow milk foam, which can prevent the crayfish's sperm from being affected by the outside world and protect the survival of the sperm.
When the female shrimp lays eggs, it will stick to the back of the crayfish by a "yellow" color in the milk foam produced in the belly of the crayfish.
The female shrimp will then use her toes to stick this yellow thing to the back of the crayfish.
This yellow substance is produced in the body of the female shrimp, called the yolk, when the crayfish is born, it will eat the yolk in the female shrimp's body to carry out cell division and nutrient absorption.
When the crayfish is born, it hides next to its parents and has milky white slender toes on its abdomen, which are also important organs for crayfish to swim.
When the belly of the crayfish is completely free, the yolk on the toes will be absorbed, the cell division will be carried out, the cytoplasm will grow, and the crayfish will grow on its own.
This yellow thing will be absorbed ten days after the crayfish is born, and then the crayfish will go through the cycle of finding food on its own, and in the process of growing, eating food, and carrying out the cycle of life.
What does it mean to "people eat color and fragrance, and demons eat shrimp and yellow seeds"?
As the crayfish grows, their parents will constantly teach them how to catch food and protect them from danger.
Crayfish in the process of growth, will also follow their parents everywhere, at this time crayfish is the most vulnerable time, easy to be threatened by small animals, but also easy to drown, so parents will take crayfish to a safe place, put in the water to grow.
When the crayfish swims, both the parents and the milk foam on the crayfish will hold the shrimp in their mouths, making it difficult to swallow the whole shrimp.
In order to prevent the shrimp from being swallowed, the crayfish will spit the shrimp into the middle of the milk foam.
At this time, the crayfish may swallow a lot of things, such as oxygen in the air, once swallowed, it will cause the crayfish to die, and the crayfish will swell in the body and cannot climb.
The oxygen in the air can only be absorbed through the lungs, and it is not possible to absorb oxygen from other places, because the oxygen in the air is humid, and if the crayfish inhale through the lungs, it will make the body shape of the crayfish and lobster unsightly.
There is a saying that "people eat color and fragrance, and demons eat shrimp and yellow seeds".
The yellow substance of crayfish is very nutritious, the yellow substance of crayfish is rich in carbohydrates and proteins, as well as a large amount of vitamin A, lecithin, etc., and is also rich in phosphatidylcholine, which has great benefits for human health.
The yellow substance on the head of the crayfish is also very helpful for the nutrition of the crayfish itself.
The yellow substance of crayfish is rich in carbohydrates, which can increase the physical strength of crayfish, make the physical strength of crayfish stronger, and the crayfish can swim more vigorously.
At the same time, it can also help crayfish to live, so that crayfish can grow better, and the yellow substance on the head of crayfish is also rich in protein, which is very helpful for the growth of crayfish.
epilogue
Therefore, the yellow substance of crayfish is very important for crayfish, crayfish often live in water, and can also help crayfish increase buoyancy, so that crayfish can swim in the water and live.
Therefore, the value of the yellow substance of crayfish is very great, and the yellow substance of crayfish can often be ingested in life, which can add more nutrients to the human body.
