In everyone's impression
Starfish are always lazily lying on the bottom of the sea
A harmless look of humans and animals...
But for days to come
"Pie Star" who once looked harmless to people and animals
In qingdao Jiaozhou Bay sea area became
The object of everyone's shouting
The reason is that there are too many
It has been flooded
The most important thing is to rush into the breeding base
And humans snatch clams, sea oysters...
It's also very good to eat
↓↓↓
However, they should not be able to bounce for a few days.
Let's answer a few questions that everyone must be concerned about
01
Why are so many starfish popping up all of a sudden?
Expert introduction,
Generally speaking, starfish themselves will move,
If suddenly in large numbers,
There may be delicacies around that attract them.
After the starfish ate food such as abalone,
will multiply in the vicinity,
The consequences are unimaginable if they are not cleared in time.
Some scholars have also said that
It is not excluded that the original living environment of the starfish group has been destroyed,
Thus the possibility of moving here.
Starfish have a super reproductive ability,
A female starfish can hold 20 million eggs at a time!
What's even more frightening is that
This cute-looking species is especially edible!
As long as it swims in the water,
Creatures smaller than it,
What oysters, abalone, sea cucumbers,
Fish eggs, crabs and scallops are all eaten,
Sometimes it's fierce,
Even his own kind...
A farmer told reporters,
These starfish are particularly destructive,
Like locusts on the ground,
Wherever the bottom of the sea goes,
There are very few farmed clams and oysters left.
"The number of starfish cannot be controlled,
We dare not sow seedlings into the sea,
Later income has become a problem! ”
"I wrapped up hundreds of acres just to raise sea oysters to make some money, so I almost lost everything!" Mr. Wang, a farmer, told reporters that he invested more than 1.7 million yuan before and after, so that Starfish could not lose all his money. "Hired boats to catch starfish, a ship a day will cost 1,000 yuan!" Mr. Wang said helplessly.

Watch how soft starfish eat shellfish with shells?
A farmer told reporters
When starfish eat
It secretes a type of mucus
It then covers the sediment on the seabed
This makes it impossible for shellfish to breathe in this sandy area
They had to "pop up"
The mucus of starfish is very damaging to shellfish
It is often more shellfish that is killed than eaten
Exactly such a feature
It is easy to see the death of clams in flaks in the farming area
And when actually eating
Starfish also have a unique approach to handling prey
The starfish's mouth is underneath it
Starfish wrap their prey with their arms
And open the housing slightly
The food is then pushed from its mouth into the shell
After the food is completely digested
Starfish will retreat because of food

Starfish plague? Is it just a matter of eating openly?
"Although starfish can eat, but the cholesterol content is relatively high, you can't eat more." A farmer at the scene told reporters that although starfish can be eaten, containing a large number of protein, amino acids and other conventional substances, but the cholesterol content is relatively high, in his view, eating too much is not too good, locals rarely eat.
It is understood that starfish has a strong reproductive ability, spawning in the spring and autumn of each year, its natural enemies (some fish) only feed on its larvae, starfish has almost no natural enemies after adulthood, once it grows up, it will be difficult to deal with. Starfish also have a strong regenerative ability, if torn into the sea, its torn limbs will produce tentacles in a short period of time, turning into multiple starfish.
Starfish eats a faint salty taste and rich umami taste, and it is also rich in nutrients, such as: protein, amino acids and a variety of trace elements, etc., starfish more common ways to eat are: steaming, cooking, steaming eggs, soup and so on.
It's worth noting that not everyone is suitable for eating starfish. Starfish is rich in xeno-protein components, people with seafood allergies should also eat starfish with caution, and those with poor digestive function should not eat too much to avoid causing symptoms of indigestion.

What is the latest situation in Jiaozhou Bay now?
At 1:15 p.m. on March 12, as the tide rose, fishing boats that had gone out to sea to catch starfish returned one after another. "I fished two or three thousand pounds on this boat, and the places where the starfish were dense, one next to the other, and some places were stacked one by one." Fisherman Mr. Lin told reporters. According to reports, each fishing boat is equipped with 1 to 4 divers, generally in the morning at dawn to go to sea, after arriving at the fishing area, divers or carry oxygen cylinders, or use air pump trachea, dive into the seabed 7 meters or deeper, by hand one to pick up starfish.
Although there were many starfish salvaged, the reporter also heard good news from some farmers. "We contracted more than 300 acres, and yesterday we went down to look for divers and found that there were fewer starfish, and it seemed that the fishing really worked." But we also have to worry about whether the starfish has eaten almost on our side, moved to another area, and will come back in a few days. Mr. Niu, a farmer, said that the starfish appeared in the breeding sea, just like the grassland fire, and the "fire" in front of his home was extinguished, but maybe it came again in the blink of an eye.
At the scene, the reporter also interviewed Mr. Yu, who had just returned from the sea, in addition to breeding oysters and clams, he recently had a new identity "diver", and his ship had thousands of pounds of starfish caught at sea that day, but for him, this was not a good thing. "The more starfish are salvaged, the more we lose!" Mr. Yu said. Another fisherman involved in the interview told reporters that in some places the number of starfish is very amazing, spreading a thick layer on top of clams, looking at it like a carpet in the sea.
In addition, The Peninsula reporter also noticed that some starfish were already very large, and starfish seeds appeared in them. "About a week ago, four or five starfish were enough for a pound, and now three are a pound. The main thing is that the water temperature is higher, and the starfish eat more and are more active. The seeds in the belly of a large starfish can account for 60%, and in ten days and a half months, the seeds inside will be full. ”
