My Deep-sea Fishery

"It's all sold, it's already sold out." Xiang Yang smiled and threw a fist at everyone. "Now my catch is limited. When I set up a fleet and can catch surplus fish, I will definitely ask for it. Everyone helped sell them together."

Tens of thousands of catties of yellow skin fish were lifted from the boat by the workers and crew together. The attraction to fishmongers is really immeasurable.

One of the fishmongers wiped his nose and sighed: "Boss, boss Li, you are too unkind, right? So many yellow skin fish are unevenly distributed to us, so many of us come from such a far place. , The private car has been waiting here for so long, so you let us go back empty-handed?"

Li Chao looked down at the guy, then set his eyes slightly, as if he hadn't seen him at all. Li Chao felt that talking to him was a waste of time.

Xiang Yang was also pure when the person was farting, so he didn't have the slightest intention to deal with it.

But one person couldn't help it.

It was Murong Zhenfei, and I saw Murong Zhenfei jump out from the crowd, "Is it my manager Xiang or manager Li who asked you to wait here? Why are we not kind? Knowing that we have received the goods from the terminal here, you come to grab it. Even if you eat, you still dare to say that President Li and Mr. Xiang are not kind. Are you teaching us how to behave?"

Murong Zhenfei's words quickly resonated with Fang Youqun.

I saw Fang Youqun standing forward, looking at the crowd with a fierce expression, and shouting along with Murong Zhenfei: "Are you teaching us how to be human?"

Looking at Fang Youqun's performance, Xiang Yang grinned, "You are really welcome to kidnapped by this kind of morality."

Strictly speaking, this is Li Chao's business field. These fishmongers are the ones who invaded. Now they are going to grab Li Chao's supply, and Li Chao will certainly not give them a face.

The seafood purchaser who was the first to speak immediately waited for a gap in the ground to let himself in.

When the tens of thousands of catties of yellow skin fish were lifted down, there were boxes of silver pomfret immediately afterwards.

Silver pomfret is a warm-temperate mid-lower fish in the coastal waters. It lives in the sea area with a depth of 30 to 70 meters. It likes to cluster in the shadows. It is a more valuable marine fish than the yellow skin.

Speaking of silver pomfret, there is another thing that makes Xiang Yang very concerned.

As one of the important candidate species for marine aquaculture, silver pomfret has received extensive attention from all over the world.

In recent years, silver pomfret has been listed as one of the four major aquaculture species with local characteristics in the Marine Germplasm Project.

Although the specific breeding method of silver pomfret has not been researched, it is fully in line with the spirit of my country’s mid- and long-term scientific and technological development plan, which proposes to "effectively increase the coverage of my country’s seawater improved species and promote a number of artificial reproduction. The process of industrialization of new marine aquaculture species that have a breakthrough, have good market potential and can represent different marine environments and different aquaculture models, accelerate the progress of the expansion of high-quality provenance, and promote the structural adjustment of marine aquaculture species in my country."

Therefore, Xiang Yang is actually concerned about the development of large-scale breeding of silver pomfret.

Xiang Yang himself has the idea of ​​doing aquaculture, but he has always been subject to technical standards, and there is a degree of saturation in the market.

Now there is no one in the world that breeds silver pomfret, but the silver pomfret breeding technology has indeed been included in one of the four major local characteristic aquaculture species in the Marine Germplasm Project.

If Xiangyang builds a silver pomfret breeding base, the upper side can obtain policy support, and the lower side can obtain the support of the villagers. Once the cultivation is successful, it will be the first silver pomfret farming company. The rich profits that come are very scary.

It is even possible that Xiang Yang can take this to become a domestic aquatic product supply giant.

Of course, this idea is still an immature idea in Xiang Yang's head.

If there is no certainty, Xiang Yang will never really try to realize this idea.

As a traditional and important fishery resource in my country, the East China Sea Pomfret has been forward-looking deployment more than ten years ago.

Since 2000, Ningbo University, the Institute of Oceanography and Fisheries, the East China Sea Fisheries Research Institute, Zhejiang University and many companies have successively undertaken the important task of research on silver pomfret.

The research on silver pomfret artificial propagation technology, silver pomfret artificial breeding technology research, silver pomfret factory breeding technology research, silver pomfret large-scale technology research and other scientific and technological projects have been studied for more than ten years. Scientists have broken through countless technical difficulties. After overcoming a difficulty, you can always encounter more new ones.

In 2015, a major science and technology project "Preliminary Technology Research and Demonstration of Silver Pomfret Industrialization" was specially set up above.

This project is hosted by Ningbo University and jointly undertaken by four units including Zhejiang University. The pre-industry research plan is five years, and the input of human and material resources is countless.

After continuous efforts, biologists and scientists have clarified the gonad development, reproductive cycle and effective accumulated temperature of the silver pomfret, combined with nutrition and light control technology, the artificial breeding of the silver pomfret has indeed been initially realized.

And scientists also discovered that jellyfish is a special source of nutrients for silver pomfret, and clarified the special nutritional requirements of silver pomfret for jellyfish.

Biologists also used ultra-high performance liquid chromatography technology to successfully screen and obtain 30 important lipid markers for silver pomfret ~www.readwn.com~ and successfully cloned the growth and fat metabolism of cultured silver pomfret. Gene.

But until 2017, the artificially farmed silver pomfret remained in the experimental sea area.

There is no way.

Because this is determined by the living habits of the silver pomfret.

Silver pomfret is a warm-temper mid-lower fish in the coastal waters, and their habitat is generally in deep water areas below 30 meters.

On the contrary, the silver pomfret likes to swim to the upper middle level of the water in the morning and dusk.

The most difficult thing to solve is that the silver pomfret still has a very obvious seasonal migration phenomenon. In winter, it needs to overwinter in the deep water area of ​​the open sea.

Every spring, as the water temperature rises, the fish schools in the wintering grounds will swim toward the sea according to their migration routes.

Among them, the most delicious schools of overwintering fish outside the northern part of the East China Sea generally start in April and move west-northwest as the warm current strengthens.

In early and mid-April, the schools of silver pomfret in Zhoushan fishing grounds and Yangtze River estuary fishing grounds increased significantly.

Sometimes, a school of silver pomfret will quickly move closer to the shore and enter the Dazhen Ocean and the coastal waters of Jiangsu to spawn.

Adult silver pomfret loves to feed on jellyfish, benthic animals and small fish.

Juvenile silver pomfret generally only feeds on small fish, arrowworms and copepods.

Adding up all these conditions, Xiang Yang feels that the breeding level of silver pomfret is much greater than that of large yellow croaker.

Shaking his head, Xiang Yang drove this unrealistic idea out of his mind.

Although the farming of silver pomfret is a good thing, if we really want to practice it, we should wait for scientists to cultivate fry that can really adapt to survival in the wild.
