"It's not just that simple. Vampire squids are very smart." Zhang Qicheng said proudly, "When they are in the deep sea, vampire squids not only turn off the lights and hide in the dark as a means of escape, they also know how to use lights to confuse their opponents."
Xiang Yang nodded.
Yes.
When a vampire squid senses danger in the deep sea, it will wrap itself up with a thin membrane and tentacles, with only two light-emitting organs on its head exposed, which emit a very dazzling light. Then the light will dim little by little, giving predators the illusion that it has escaped far away.
Vampire squids use this method to avoid most marine predators in the deep sea.
In addition, vampire squids can also "split into two".
If a marine predator is very close to it and its confusing means are no longer enough to deceive the marine predator, it will instantly spray out a large amount of luminous ink to confuse the predator, and then it will instantly become dim and run away.
These amazing abilities have enabled the vampire squid to survive even when almost all other species have become extinct during the same period.
"This vampire squid is not cheap, right?" Xiang Yang was obviously most concerned about the price of the vampire squid.
Vampire squids and octopuses have a common ancestor. The biggest difference between them and ordinary octopuses is that they hide in the deep sea, where they can be found everywhere.
It is difficult for ordinary fishermen to catch vampire squids in the deep sea, but it is not difficult for Xiang Yang to catch them.
If these vampire squids are really valuable enough, Xiang Yang is still willing to dive into the deep sea to catch some.
"Not very expensive." Li Chao obviously saw through Xiang Yang's thoughts. He said, "In terms of edible value, vampire squid is not a seafood accepted by the public. Its edible value is not as high as its ordinary value. Its main value comes from its ornamental value."
"Although the vampire squid is a marine ornamental fish, it can be classified as one of the three major series of tropical freshwater ornamental fish. The one Lao Zhang brought back is worth about two thousand yuan. They live in the deep sea and are difficult to catch. The effort is not proportional to the reward. I suggest you don't try to catch this thing."
"There are three major series of tropical freshwater ornamental fish?" Xiang Yang asked.
"Yes, but you are not specialized in freshwater fish, so you may only know the angelfish series." Zhang Qicheng smiled and said, "The three major series of tropical freshwater ornamental fish are lantern fish, angelfish, and dragon fish."
Xiang Yang raised his eyebrows, "Angelfish is actually a series?"
"That's right." Zhang Qicheng nodded.
"Marine ornamental fish are not actually popular. The existing marine ornamental fish mainly come from the coral reef waters of the Indian Ocean and the Pacific Ocean. Although there are not many species, they have strange colors and a primitive, simple and mysterious natural beauty."
"The most popular ornamental fish are undoubtedly temperate freshwater ornamental fish, such as red crucian carp, goldfish, and koi. These are household names and are unmatched by any marine fish."
Goldfish are considered to be the earliest ornamental fish. Raising goldfish is one of people's common hobbies, just like raising cats and dogs.
Especially in the late 1980s, the ornamental fish market in Guangzhou gradually expanded. At that time, almost one out of every three households in Guangzhou had a fish tank.
A common "lion head" can be sold in an aquarium store for tens to hundreds of yuan. From that time on, goldfish have shown aristocratic origin.
However, goldfish are difficult to raise and have a low survival rate. They will usually die if the water is not changed for two days or if you forget to feed them for one day. Therefore, the number of people raising fish gradually decreased in the early 21st century.
The aquarium market has also shifted from cultivating large quantities of fish fry to cultivating high-quality fish species as the mainstream.
The price of noble goldfish began to rise sharply.
Koi became a goldfish star in the early 1990s. An expensive koi could be sold for thousands or even tens of thousands of yuan in that era.
I don’t know when Arowana became famous overnight after Koi.
A dragon fish with excellent shape and color will be sold for at least 30,000 yuan.
Especially in recent years, the prices of koi and red dragon have almost been driven up to the sky. The price of an adult red dragon with a noble body, scale color, and posture can almost buy a small-property house in a super first-tier city like Guangzhou.
However, this year the status of temperate freshwater goldfish seems to have been challenged by tropical freshwater lamp fish. "Fluorescent fish" is a new species introduced from abroad in the past two years. This fish can emit faint fluorescence in a dark environment. The price of a small fish less than two centimeters in length is as high as 90 yuan, and the appearance is not even considered.
After understanding the market situation, Xiang Yang pondered for a moment and asked, "Do fish farmers now like to raise glowing fish?"
"That's not the case. It depends on the appearance." Li Chao said with a smile, "Lantern fish is the most famous luminous fish. If you were to take this fish, would you keep it for fun?"
Lantern fish is monkfish.
A kind of marine fish that is as ugly as the croaker.
Xiang Yang nodded. Raising that kind of fish was indeed disgusting.
However, Xiang Yang has a luminous sea fish other than the lantern fish, which is the sunfish he caught from the sea some time ago.
That’s right, sunfish is also a bioluminescent marine fish.
In addition to being called sunfish by fishermen, it also has a very nice name, called moonfish.
Sunfish live in tropical oceans, and there are often many luminous animals attached around their bodies. When they swim, their bodies emit shining light, which looks like a bright moon from a distance, so they are called moonfish.
So Xiang Yang told Zhang Qicheng about the sunfish.
He said, "Mr. Zhang, I caught a sunfish on my boat. Would you like to bring it over to keep?"
"Sunfish?"
"Keeping it?"
Zhang Qicheng and Li Chao both looked at Xiang Yang in surprise, "Can the fish still be alive after being caught?"
The sunfish is a very strange marine fish. It has a very strong vitality. Even if it is bitten by a sea lion and then thrown onto the beach, it can still live for a long time.
But if you say that their vitality is fragile, then it is indeed very fragile.
Sunfish are a type of fish with extremely low psychological stress tolerance. Any fright can make them very nervous, and once they are nervous, they will commit suicide directly.
Xiang Yang nodded, "Still alive."
Li Chao was not very interested in the sunfish. "The intestines of that kind of fish are a very high-end ingredient, but I don't want the fish meat except the intestines."
Xiang Yang looked at Zhang Qicheng.
Zhang Qicheng smiled and shook his head. "A sunfish has at least several hundred kilograms of meat. The meat of this kind of fish is not easy to sell. If you can't sell it, you can send it to me and I will make it into fish balls for you to eat."
