Lobster I really only saw the red, then the blue lobster and how it is? Blue lobster can eat? What causes into a blue lobster? Here we come together to see it!

British fisherman caught a rare blue lobster

According to the British "Daily Mail" reported on August 24, Britain, a fisherman on the coast of Devon captured a rare blue lobster. The probability of catching a blue lobster is said to be one in two million. The fisherman named the lobster "Larry" (Larry) and released it back into the sea.

The fisherman's name is Keith Setter.

The fisherman's name was Keith Setter, and he was fishing for shrimp in Ladram Bay at the time. Setter said he had been fishing in the bay for 50 years and had never seen such a lobster. Due to a genetic abnormality, Larry's body produces more of a certain protein than other lobsters, hence the bright blue color around his body. And fishermen believe that meeting such a blue lobster is an auspicious omen, a sign of good luck, so they usually don't eat it.

Like other lobsters, this one turns bright red when cooked. But Larry escaped becoming a delicacy because Sater decided to release him into the sea along with two other lobsters caught at the same time. According to Sater, "Hopefully, when another fisherman catches Larry in a few years, it will be as enjoyable a treat as we are seeing him today."

What's going on with the blue lobster

From the outside, the blue crayfish is slightly smaller than the other red lobsters, compared to the hardness of the red crayfish shells to be a little softer. The white crayfish body white, in the red crayfish appear very "eye-catching". Reporters visited the market several lobster merchants learned that the blue and white crayfish is rare, why the lobster will change color, the merchants are not clear why.

In response to the formation of blue crayfish, netizens have different discussions. Some netizens believe that the crayfish blue may be environmental pollution caused by its mutation, can not be eaten casually; some netizens believe that this is the crayfish after the birth of a genetic mutation, rather than by heavy metal pollution, can be eaten.

In fact, the Internet on the "small blue shrimp" and "small white shrimp" debate abounds, in many places have been reported. We are generally concerned about the focus is: these crayfish in the end how to appear? Is it pollution or genetic mutation?

Blue and white crayfish in our country, there are two possibilities: one is introduced from abroad; the second is due to the endocrine role of the crayfish and the environment, food and other factors that lead to changes in individual crayfish. Among them, the endocrine role of the individual may be the main cause, because the crayfish body has a substance called astaxanthin, which has a red, brown, blue and other colors, localized to what color is dominated by the shrimp shells will show what color, these are all due to the individual and change.

Blue lobster can eat

Blue crayfish caused by mutations can be eaten

So what exactly is the reason for the crayfish into a blue color, it can not be eaten? Recently, the reporter visited the Aquatic Research Institute in Wanzhou District, Chongqing, to aquatic professionals to understand the specific reasons.

"This blue crayfish may be caused by a variety of reasons, because there is no see its evolution, can not be sure what it is caused by." Aquatic experts told reporters that the most likely is due to changes in the environment and caused by mutation, like long-term attachment to algae such as cyanobacteria will cause changes in shell color. Blue is just a color in the mutation process, may also mutate into other colors. There may also be ordinary crayfish and Australian shallow water lobster hybridization and the formation of the Yangtze River is now mixed with a lot of exotic organisms, resulting in the mutation of the species.

"The blue crayfish is not poisonous, but only the shell color change due to some reason, but as long as the shrimp's muscles and internal organs are the color of normal shrimp, can be eaten." Aquatic experts say that crayfish like this particularly good-looking color are often kept by people as an ornamental pet.
