My Deep-sea Fishery

"It's all sold, it's all sold." Xiang Yang smiled and clasped his fists at everyone, "Now my catch is limited. When I form a fleet in the future and I can catch a surplus of catch, I will definitely invite you Let’s help sell it together.”

Tens of thousands of catties of yellow-skinned fish were lifted off the boat by the workers and crew. The attraction to fishmongers is really immeasurable.

One of the fishmongers wiped his nose and murmured, "Boss Boss, Boss Li, are you being too unkind? So many yellow-skinned fishes are not evenly distributed to us, so many of us came from such a long distance." , the special car has been waiting here for so long, and you let us go back empty-handed?"

Li Chao looked down at that guy, and then closed his eyes slightly, as if he didn't see that person at all. Li Chao felt that talking to him was a waste of time.

Xiang Yang also thought that person was farting, so it was useless to talk to him.

But one person couldn't help it.

It was Murong Zhenfei, and Murong Zhenfei jumped out from the crowd, "Is it Mr. Xiang or Mr. Li who made you wait here? Are we being unkind? We know that we have received the goods at the wharf here, so come and grab them." Forget about eating, but you dare to say that Mr. Li and Mr. Xiang are not kind, are you teaching us how to behave?"

Murong Zhenfei's words quickly resonated with Fang Youqun.

Fang Youqun stood forward, looked at the crowd with a ferocious face, and shouted along with Murong Zhenfei, "Are you teaching us how to be human?"

Seeing Fang Youqun's performance, Xiang Yang immediately grinned, "You really don't have to be polite to this kind of moral kidnapping."

Strictly speaking, this is Li Chao's business field, and these fishmongers are invading. Now that they want to grab Li Chao's supply, Li Chao will certainly not show embarrassment to them.

The seafood purchaser who spoke first immediately wished there was a gap in the ground for him to slip in.

When the yellow-skinned fish weighing more than 10,000 catties was lifted down, there were boxes of silver pomfrets immediately after.

Silver pomfret is a warm-temperate middle and lower layer fish in the offshore. It inhabits sea areas with a water depth of 30-70 meters. It likes to gather in the shadows. It is a sea fish that is more valuable than yellow-skinned fish.

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

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

In recent years, silver pomfret has been listed as one of the four main local characteristic aquaculture species in the marine germplasm project.

Although the specific breeding method of silver pomfret has not been researched yet, it is completely in line with the spirit of my country's medium and long-term scientific and technological development plan, which proposes to "effectively increase the coverage rate of my country's seawater improved species, and promote a batch of artificial breeding that has reached the stage. The industrialization process of new mariculture varieties that have breakthroughs, have good market potential and can represent different sea environment and different farming models, accelerate the expansion of high-quality provenance, and promote the structural adjustment of mariculture species in my country.”

Therefore, Xiang Yang actually cared about the large-scale breeding of silver pomfret after all.

Xiang Yang himself has the idea of ​​doing aquaculture, but he has always been subject to the level of technology and the degree of saturation of 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 main local characteristic aquaculture species of the marine germplasm project.

If Xiang Yang builds a breeding base for silver pomfret now, he can get policy support from the top, and support from the villagers on the bottom. The huge profits that come from it are very terrifying.

It is even possible for Xiang Yang to use this to become a domestic aquatic supply giant.

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

If he is not sure, Xiang Yang will never really try to realize this idea.

East China Sea silver pomfret is a traditionally important fishery resource in my country. As early as more than ten years ago, some people started forward-looking deployment.

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

Research on artificial breeding technology of silver pomfret, research on artificial breeding technology of silver pomfret, research on industrialized seedling breeding technology of silver pomfret, research on large-scale technology of silver pomfret and other scientific and technological projects have been studied for more than ten years. Scientists have broken through countless technical difficulties, but every time After overcoming a difficulty, there will always be more new difficulties.

In 2015, a major science and technology special project "Pre-stage Technology Research and Demonstration of Silver Pomfret Industrialization" was set up.

This project is presided over by Ningbo University and jointly undertaken by four units including Zhejiang University. The pre-industrial research plan is 5 years, and countless manpower and material resources have been invested.

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

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

Biologists also successfully screened and obtained 30 important lipid markers of silver pomfret by using ultra-high performance liquid chromatography technology, and successfully cloned genes related to the growth and fat metabolism of silver pomfret.

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

There is no way.

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

Silver pomfret is an inshore warm-temperate middle and lower layer fish, and their habitat is generally in the deep water area below 30 meters.

However, silver pomfret likes to swim to the middle and upper layers of the water in the morning and dusk.

The most difficult thing to solve is that silver pomfret still has a very obvious seasonal migration phenomenon, and it needs to survive the winter in deep water areas in the open sea in winter.

Every spring, as the water temperature rises, the fish schools in each wintering ground will swim to the offshore according to their own migration routes.

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

In early and mid-April, the number of silver pomfret fish in the Zhoushan fishing ground and the Yangtze Estuary fishing ground increased significantly.

Sometimes, the silver pomfret school will quickly move closer to the shore, entering the Atlantic Ocean and Jiangsu coastal waters to spawn respectively.

Adult silver pomfrets love to feed on jellyfish, benthic animals and small fish.

Juvenile silver pomfret generally only feed on small fish, arrowworms and copepod marine life.

Adding up all these conditions, Xiang Yang felt that the silver pomfret was raised much more than the large yellow croaker.

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

Although the farming of silver pomfret is a good thing, if we really want to practice it, we have to wait for scientists to breed fish fry that can really survive in the wild.
