My Deep-sea Fishery

Despite the fact that most krill have a very potent toxin if not handled properly after death, krill is still considered a potential food source for humans due to its sheer abundance and high nutritional content.

Especially Antarctic krill, it can provide a large amount of vitamin A for the human body, and the quantity is very rich. According to the incomplete statistics of the United Nations, the annual output can reach 500,000 tons, and the total quantity exceeds 100 billion tons. It is the largest food warehouse for human beings in the future. .

Of course, because today's fishing technology is not advanced enough, it is difficult for Antarctic krill to be transported back to the shore alive. Therefore, krill is not used as human rations most of the time, but as an important food resource for pets or aquatic products. The main feed for aquaculture.

Especially in my country, because my country's distant water fishing industry started late, many technologies cannot keep up with other major fishing countries in the world, and the number of Antarctic krill caught each year is even less.

Of course, this is also related to our country's strong environmental awareness.

Like Russia, their deep-sea fishing technology is also very advanced, but because countries all over the world fished Antarctic krill in Antarctica in the 1980s and 1990s, resulting in a sharp decline in the number of Antarctic krill, Russia announced that it would give up fishing for krill.

Prior to this, Russia was the largest fisher of krill in the entire Antarctic, with an annual catch of more than 100,000 tons.

However, it is worth mentioning that Antarctic krill cannot be directly fed to cats and dogs as pet food.

Antarctic krill contains more salt than ordinary shrimp, and the taste is saltier. Cats and dogs are generally not suitable for eating too much salt.

If it is to be eaten by humans, the krill must have their shells removed.

At this time, Fang Youqun used a piece of bamboo with a long ground cage net tied to the front of the bamboo to probe into the ice cave, and then with the joint efforts of several people, he struggled to get the ground cage out of the ice cave.

Sure enough, the cages were full of Antarctic krill.

Hey, Brother Yang, look, I caught a very big Antarctic krill. Fang Youqun opened the ground cage net, and was about to clean up the Antarctic krill inside. Suddenly, he seemed to have found something, and he was extremely excited. shouted.

Xiang Yang turned his head to look there, and sure enough, Fang Youqun was holding a prawn that looked like Antarctic krill but was four to five centimeters in size.

Compared with the one or two centimeters of ordinary Antarctic krill, four or five centimeters is definitely a giant.

This is not Antarctic krill. Xiang Yang shook his head.

Gao Chuang also said happily: This thing doesn't even count as shrimp, but you are lucky, you caught one of these.

When Fang Youqun heard this, he immediately excitedly said, Is this thing very valuable?

It's not a question of whether it's worth it or not. It's just that it's hard to catch. It's called a salp. It generally likes to live in the cold waters of the Southern Ocean. It's a kind of marine life that is very important to its environment.

A salp is a marine invertebrate that looks a lot like Antarctic krill, but it's not Antarctic krill.

In the past, there were quite a few fleets that caught salp, and it was once mistaken for the king of Antarctic krill.

In fact, salps are more like a type of jellyfish.

Saying that salps are very important to the sea environment where they live does not mean that they are a very important link in the marine food chain, but that salps can transport carbon from the ocean surface back to the depths of the ocean and give it to the atmosphere. Carbon offers an opportunity to move away.

Look again, there should be more than one salp here. Like Antarctic krill, salps are also in groups. Moreover, salps and Antarctic krill are competing with each other. Their food is roughly the same. Since this area If there are so many Antarctic krills, there must be no fewer salps. Xiang Yang ordered.

Moreover, Antarctic krill is the main source of food for many Antarctic creatures, such as penguins and killer whales, but salps are basically absent and animals will eat them. As long as Antarctic krill and salps coexist in sea areas, salps will basically follow. The population of Antarctic krill is decreasing and increasing.

Xiang Yang twisted the salp and put it in the palm of his hand for a closer look, In Antarctica, there are many unique marine creatures, such as icefish with milky white blood, and this salp can actually be regarded as a unique marine species. Biological, it has a unique open-tube blood circulation system in its body, every few minutes, the blood in its body will be reversed once.

The reason why Xiang Yang asked Fang Youqun to take a closer look to see if there were any salps in the fish basket was not because salps were more valuable than Antarctic krill, Xiang Yang wanted to single them out.

Xiang Yang just wanted to make a simple classification. Salps are salps, and Antarctic krill are Antarctic krill. These two creatures should not be mixed together.

As for the price, if it is really sold in the market, the sales of this salp is probably not as good as that of Antarctic krill.

At this time, a crew member in the distance suddenly shouted loudly: Ice fish, everyone, come and see, there are ice fish under the ice cave on my side.

Everyone was immediately attracted.

There are a lot of Antarctic krill, but the real moneymakers have to be top seafood like ice fish.

You're busy with your work, I'll go over there first. Gao Chuang hurriedly walked over there.

Xiang Yang looked at Chen Qingsheng and said, Come on, let's go and have a look.

When Xiang Yang arrived at the ice cave, it was already surrounded by people from various ships.

But after waiting for Gao to get there, the crowd dispersed immediately, and they were all busy again, but their eyes drifted here from time to time.

Taking the opportunity, Xiang Yang finally arrived at the edge of the ice cave and looked down. Sure enough, he saw a dozen very fat ice fish greedily preying on Antarctic krill under the ice cave. Under the ice cave, it seems to be breathing.

Is there a way to catch these ice fish? Gao Chuang immediately asked around.

He has already seen ice fish with his own eyes. If Gao Chuang didn’t catch it, he would not be a fisherman. After passing through, he knew that ice fish swims very fast under the water. With such a thick layer of ice, the hope of catching it is very slim. , but it's something to try, isn't it?

Boss, we will try our best. A fisherman in his thirties and forties with a big mink on his body said immediately.

Xiang Yang glanced at the person who spoke. Xiang Yang knew this person, his surname was Zhang, and he was the captain of one of the trawler in Gao Chuang's fleet.

Well, don't be pressured, just let go and catch it. If you don't catch it, you won't catch it. I won't blame you. If you catch it, I will give you a bonus at the end of this month. Gao Chuang said loudly.

Captain Zhang immediately smiled wryly upon hearing this.

If it wasn't on the ice, even if he jumped off, he would definitely grab one or two of them, but it was on the ice, how could he let go and grab it?
