I can see the commodity price curve

Zhang Yue walked forward, patted Zhao Minghui on the shoulder, and said, "Academician Zhao, you are too polite.

We are now in the same boat, and our goal is to overcome the problem of breeding large yellow croaker.

Don't put too much pressure on yourself, your health is the capital of revolution."

Zhao Minghui smiled bitterly and said, "I know that, but seeing the experiment progress so slowly, I feel anxious.

Over the past three months, we have tried various methods, but the fertilization and hatching rates of yellow croaker are still pitifully low."

Zhan Rongrong frowned, thought for a moment and said, "Academician Zhao, do you think we are still lacking in simulating the natural breeding environment of yellow croaker?
After all, the breeding environment of wild yellow croaker is complex and diverse, and the conditions in our laboratory may still be too simple."

Zhao Minghui's eyes lit up: "Manager Zhan, your words really reminded me.

We have previously focused on technical research and ignored the impact of environmental factors on the reproduction of yellow croaker.

Perhaps we can further optimize the environment of the experimental breeding area to simulate conditions closer to the habitat of wild yellow croaker."

Zhang Yue nodded in agreement: “This is a good idea.

We can go to the wild to investigate the natural habitat of yellow croaker and collect relevant data.

For example, water temperature, salinity, water flow rate, water quality, etc., and then they can be precisely regulated in the experimental breeding area.”

The research team took action immediately.

They organized a field survey team to conduct field surveys in the main habitats of yellow croaker.

During the inspection, everyone used professional equipment to record the environmental parameters of each area in detail, and collected water and sediment samples and brought them back to the laboratory for analysis.

After returning to the laboratory, the team members immediately carried out a comprehensive transformation of the experimental breeding area based on the data from the field survey.

They installed advanced water temperature regulation systems, salinity control devices and water flow simulation equipment to accurately simulate the environmental conditions of wild yellow croaker habitats.

At the same time, the feed was optimized and some nutrients were added to help the reproduction of yellow croaker.

But no matter how hard everyone tries, they still can't find the key to the reproduction of yellow croaker.

seaside.

Zhang Yue looked at Zhan Rongrong who was pulling up a fishing boat and preparing to go out to sea, with helplessness on his face:

"Are you crazy? The weather forecast for the next two days isn't going to be good.

It is very dangerous to go looking for a school of yellow croaker now."

Zhan Rongrong gritted her teeth and shook her head, “Brother-in-law, of course I know the danger.

However, according to the living habits of yellow croaker, the only time to find their schools is in the last month.

If you miss it, you have to wait another year.

I don’t have time to wait that long.”

Zhang Yue frowned, his expression full of worry. He quickly walked to Zhan Rongrong and opened his arms to stop her:
"Rongrong, even if time is tight, you can't ignore your own safety.

The sea is unpredictable. What if something goes wrong? "

Zhan Rongrong's eyes were red, and her eyes were full of determination and anxiety:
“Brother-in-law, I understand your concerns, but the lab has tried so many methods and there has been no progress.

This is our last hope, I must try it.

If we can find a school of fish within this month and observe their reproduction behavior in their natural state, we might be able to find a breakthrough.”

At this time, Academician Zhao Minghui also hurried over. He adjusted his glasses and advised:

"Manager Zhan, Zhang Yue is right, safety comes first.

Field surveys are inherently risky, and now the weather is unstable, which undoubtedly increases the risk factor.

We can think of other ways and don’t have to take this risk.”

Zhan Rongrong seemed to be determined. She shook her head vigorously:

“Academician Zhao, you and your brother-in-law have contributed so much to this project, and I know you are more anxious than I am.

But I don't want to sit there and wait any longer, I have to go.

I have contacted experienced fishermen who will keep me safe.”

Seeing that his persuasion was fruitless, Zhang Yue sighed helplessly: "Since you insist so much, I will go with you.

One more person means more strength and more protection.”

Zhan Rongrong widened her eyes and quickly refused: "No, brother-in-law, this is too dangerous, I can't let you take the risk."

Zhang Yue patted his chest, his eyes firm: "What nonsense are you talking about? We are a family and partners fighting side by side.

We share happiness and difficulties, how can I let you go alone? "

Finally, under Zhang Yue's insistence, Zhan Rongrong had no choice but to agree.

The two followed the fishermen onto the fishing boat and headed out into the vast ocean.

At first, the sea was calm and the sun shone on the sea, making it sparkle.

But as the ship went deeper into the sea, the sky became increasingly gloomy and the sea breeze began to become fierce.

The fishermen looked solemn and vigilantly observed the movements around them.

"The weather changes so quickly, everyone please be careful." shouted an old fisherman.

Zhang Yue held onto the side of the boat tightly, feeling somewhat nervous, but he still pretended to be calm and comforted Zhan Rongrong:
"Rongrong, don't be afraid, I'm here."

Zhan Rongrong nodded, but her eyes were always fixed firmly on the distance, praying silently in her heart that she could find a school of yellow croaker.

Suddenly, huge waves surged up on the originally calm sea, and the fishing boat was thrown high up and then fell heavily.

Everyone was shaken to the ground and cried out in surprise.

"Everyone hold on tight, the waves are pretty big!" the old fisherman shouted loudly, trying hard to control the boat.

Just then, the sky was covered with dark clouds and raindrops as big as beans poured down, hitting my face and causing pain.

The wind was howling as if it was going to capsize the entire ship.

"Oh no, it's a storm!" shouted a fisherman.

Zhang Yue and Zhan Rongrong's faces turned pale in an instant. They hugged each other tightly, their hearts filled with fear.

But at this moment, they had no way to retreat and could only hold on to the fixed objects on the boat and pray that they could survive this disaster safely.

Under the ravages of the storm, the fishing boat was like a helpless leaf, struggling in the rough sea.

After an unknown amount of time, the storm finally subsided and the sea slowly returned to calm.

However, when everyone recovered from their fear, they found that the fishing boat had deviated from its original route and was lost in the vast ocean.

There was vast ocean all around, with no sign of land.

"It's over, we're lost." said a fisherman in despair.

Zhang Yue suppressed his fear and comforted everyone: "Don't panic, we will definitely find a way.

Let's check the supplies on board first and see how long we can hold out."

Everyone started to get busy, counting the food, fresh water and fuel on the ship.

Zhan Rongrong blamed herself: "It's all my fault. If I hadn't insisted on going out to sea, we wouldn't have fallen into this predicament."

Zhang Yue patted her shoulder and said gently, "Rongrong, this is not your fault. None of us wants to encounter such a thing. The most urgent thing now is to find a way to ask for help and then find a way back."

Just when everyone was at a loss, a fisherman suddenly pointed to the distance and shouted: "Look, there seems to be a small island over there!"

Everyone looked in the direction of his finger, and sure enough, the outline of a small island appeared vaguely in the distance.

Everyone suddenly felt hopeful and worked together to paddle towards the island.

After a difficult voyage, the fishing boat finally reached the shore.

Everyone landed on the island exhausted and collapsed on the ground.

Zhang Yue looked around and found that the island was deserted and covered with lush vegetation. From time to time, he could hear some strange animal calls.

"It seems that we can only stay on this island temporarily and then find a way to ask for help." Zhang Yue said.

Zhan Rongrong nodded, but she was still worried about the problem of yellow croaker reproduction.

However, in order to survive on the island, Zhang Yue and Zhan Rongrong still followed the fishermen.

They first looked for drinkable water on the island.

After some searching, we finally found a small pond in a low-lying area.

Although the water is a bit turbid, it is barely drinkable after being treated with a simple filtering device.

Then they looked for something edible on the island.

The fishermen were experienced and helped them find a lot of wild fruits and catch some small game.

Although Zhang Yue and Zhan Rongrong rarely come into contact with such wild life, they don't care about much at the moment. They work hard to help process the food and strive for survival.

At night, they built simple shelters with picked up branches and leaves. Several people huddled together to resist the cold night on the island.

Zhan Rongrong leaned against Zhang Yue and said softly, “Brother-in-law, I didn’t expect that we would encounter such a thing.

But now that I can face it with you, I am not so scared anymore."

Zhang Yue smiled and said, "Rongrong, don't worry, we will definitely get through this difficult time.

Maybe there will be new discoveries on this island.”

As the days passed, they gradually adapted to the wilderness survival life on the island.

In addition to looking for food and water every day, they also explore around the island.

That day, Zhang Yue was strolling on the island as usual when he suddenly heard a strange sound of flowing water.

He walked in the direction of the sound, pushed aside a patch of dense grass, and a hidden bay appeared before him.

The water in the bay is crystal clear, and schools of yellow croakers are swimming in the water. Their schools are dense and orderly, and from time to time you can see some yellow croakers breeding.

Zhang Yue widened his eyes, unable to believe what he had discovered.

His heart was beating wildly with excitement and he quickly ran back to call Zhan Rongrong and the fishermen.

Everyone followed Zhang Yue to the bay and were stunned by the scene before them.

Zhan Rongrong said excitedly: "Brother-in-law, this is simply a miracle!
We have been searching for it for so long and have not found it, but we discovered the habitat of the yellow croaker on this small island.”

Zhang Yue nodded, and he and Zhan Rongrong immediately took action.

Using simple measuring tools they carried with them, they began to measure parameters such as the water temperature, salinity, and water flow speed of the bay. They also collected water and sediment samples to take back to the laboratory for further analysis.

At the same time, they used cameras to record the reproduction process of yellow croaker in its natural state, not missing any details.

“Brother-in-law, look at these yellow croakers, their reproductive behavior in the natural environment is completely different from what we observed in the laboratory.

There seems to be a particular pattern in where they choose to lay their eggs, and the speed and direction of the water flow during spawning also seem to be crucial.”

Zhan Rongrong said as she recorded.

Zhang Yue nodded and said, "Yes, the environment we simulated in the laboratory before may not be accurate enough.

The environmental conditions here may be the key to the reproduction of yellow croaker.

We must bring this data back intact so that our colleagues in the laboratory can study it carefully.”

In the next few days, Zhang Yue and Zhan Rongrong stayed by the bay day and night, carefully observing the movements of the yellow croaker.

They found that when reproducing, large yellow croakers choose some places with special terrain on the seabed as spawning grounds. These terrains can provide a good attachment and protection environment for fertilized eggs.

Moreover, the speed and direction of water flow will affect the diffusion and hatching of fertilized eggs. Suitable water flow conditions can increase the survival rate of fertilized eggs.

As their observations deepened, they also noticed that the water quality in the bay and the microbial community in the bottom mud also had an important impact on the reproduction of yellow croaker.

Some trace elements and microorganisms in the water can provide necessary nutrients and a good ecological environment for the reproduction of large yellow croaker.

“Brother-in-law, let’s record all these findings.

After bringing it back to the laboratory, maybe we can adjust the environment conditions that are more suitable for the reproduction of yellow croaker."

Zhan Rongrong said excitedly.

Zhang Yue smiled and said, “Yes, this unexpected discovery really gave us a new direction.

But now we have to find a way to leave this island and bring these valuable data back."

The two began to try to make a signal transmitter using materials on the island, hoping to send a distress signal to the outside world.

After several days and nights of hard work, the signal transmitter was finally completed.

Zhang Yue and Zhan Rongrong started the launcher with trepidation, waiting for rescue.

While waiting, they were not idle and continued to monitor and record the environment of the bay.

Finally, one evening, they received a response from a rescue boat.

When the rescue boat appeared at the entrance of the bay, the crowd cheered excitedly.

Everyone quickly boarded the rescue boat. On the boat, they had no time to rest and could not wait to start organizing all the data and samples collected during this period.

There was excitement in Zhang Yue and Zhan Rongrong's eyes, as they were well aware of the importance of this information in overcoming the problem of yellow croaker breeding.

After returning to the laboratory, the team members immediately gathered around and looked at the precious information brought back by Zhang Yue and Zhan Rongrong, their eyes full of anticipation.

Academician Zhao Minghui excitedly shook Zhang Yue's hand and said, "You have really made a great contribution this time!

These findings may be the breakthrough we have been looking for.”

Next, the team members immediately plunged into intensive research work.

They remodeled the experimental breeding area based on the environmental data of the bay.

According to the seabed topography of the natural habitat of yellow croaker, special artificial reefs and caves are set up in the breeding area to simulate an environment suitable for yellow croaker spawning.

At the same time, parameters such as water temperature, salinity, and water flow speed are precisely controlled to make them completely consistent with the environment of the bay.

In terms of feed, researchers further optimized the feed for yellow croaker based on analysis of collected water and sediment samples.

They added trace elements and microbial preparations unique to the bay, hoping to provide more adequate nutrition for the reproduction of yellow croaker.

After everything was ready, the team put the carefully selected yellow croaker into the renovated experimental breeding area.

With a feeling of trepidation and anticipation, everyone stayed by the breeding area day and night, carefully observing the big yellow croaker's every move. (End of this chapter)
