Golden Fishing Village

Ao Muyang wanted to catch bluefin tuna. Even if he could only catch one female fish, as long as it was a female fish with roe, that fish could create a fish farm.

Bluefin tuna are very fertile. A fish weighing 100 kilograms can produce 5 million roe a year, and they can live for 30 years!

After these roe are hatched into fish, it is impossible for all of them to grow up. In fact, the survival rate in one year is less than one in ten thousand, and the survival rate in ten years is less than one in one hundred thousand. Don’t be fooled by their ability to grow very large:

Yellowfin tuna can grow up to two meters, albacore tuna can grow up to one meter and four, bigeye tuna can grow up to two meters and four, and bluefin tuna is even more exaggerated, some can grow up to four meters!

But when they are just hatched, they are the same size as seaweed and duckweed. During their growth, they will be constantly hunted by other marine life.

In other words, if tuna grows up, it will be a lot of RMB, and if it doesn’t grow up, it will be the food of a group of fish, shrimps and crabs.

It can be sold for money and used as natural feed. For the fishery, this thing is too precious!

Unfortunately, Ao Muyang didn't have this luck.

He threw out two golden drops in a row, attracting a bunch of fish, but there were no bluefin tuna.

After all, it was too late when he released the golden drops. The tuna had long disappeared. The temptation of the golden drops could not be without distance limit.

Because the tiger was guarding beside, the fish and shrimps attracted by the golden drops were afraid to approach and only dared to watch from a distance.

Ao Muyang also looked at the seabed around him, wanting to see if the tuna would come back.

Unfortunately, they didn't come back.

Seeing this, he waved his hand with a lack of interest. The tiger was still staring at the golden drops, and immediately pounced on them like a hungry tiger.

As soon as the tiger left, the other fish came to snatch the food from the tiger's mouth, and scrambled to swim to another golden drop.

In a flash, a torpedo-like figure swooped down from the sea above. With its round body and crescent-shaped tail, Ao Muyang was stunned!

A bluefin tuna!

Not all tunas left. One fish may have returned, or it may have left the school of fish at the beginning. In short, it was also attracted by the golden drop.

But it was always wandering on the surface of the sea. Ao Muyang stayed in the sea and paid attention to the seabed. He didn't look up, so he didn't see the fish.

As soon as the bluefin tuna came out, Ao Muyang immediately waved his hand and pointed it up.

The general received the order, and the big tail swung to stir up a torrent. With a "whoosh", he broke through the seawater and swam quickly.

The tuna wanted to run away after eating the golden drop, but how could it be so easy? The tiger was eyeing it!

And because the tiger was in the lower layer of the sea this time, when it rushed up, the tuna couldn't dive to escape, and it had to continue to swim to the upper layer of the sea.

It swam quickly in the sea water, and there was another figure chasing after it even harder, that was Huang Xiaodi!

Huang Xiaodi was almost mad, and he chased after it like a hound with his teeth bared: There were two golden drops in the water, one was from the tiger, and he had no problem with it, but the other one should be his!

The bluefin tuna ate the golden drops, which made Huang Xiaodi very angry, and he chased after it harder than the tiger.

After repeated interceptions, the bluefin tuna was finally hit by the tiger...

This bluefin tuna was about one and a half meters long, which was not enough for the tiger that was more than four meters long. When the tiger approached it, its speed began to slow down.

When the tiger swam, the turbulence generated by the friction between its body and the sea water was very strong, which affected the balance of the bluefin tuna and naturally made it unable to swim fast.

After the tuna was hit, it rolled repeatedly in the water. Ao Muyang reversed the golden elixir and chased after it, and grabbed the tuna in his hand.

After the fish was caught, he still felt embarrassed and difficult to handle!

As we all know, the breathing organ of fish is the gills. Whether swimming or still, their gills always open and close to absorb dissolved oxygen in the water and release carbon dioxide in the body.

But tuna uses impact breathing. They do not have the ability to actively absorb dissolved oxygen. They need to hit the water body in the water to let the seawater flow through the gills and leave dissolved oxygen to breathe.

So a problem arises. Tuna must keep swimming to breathe. Once it stops, it will lack oxygen and suffocate.

According to Ao Muyang, bluefin tuna must swim at least 65 cm per second to hit enough seawater to get oxygen.

Therefore, the bluefin tuna he caught cannot be restrained for too long, otherwise it will suffocate to death.

In addition, the fish was a little dizzy at this time, so he caught it. If the fish wakes up, he will definitely not be able to catch it with his strength.

So he made a prompt decision, dragged the gills onto the motorboat, accelerated all the way back to the fishing ground, and threw the fish into the fishing net.

This unfortunate bluefin tuna was so dumbfounded that it was floating in the water in a daze, twisting its body left and right, crooked, as if it was drunk.

Even so, it was trying hard to swim, otherwise it would suffocate to death!

Ao Muyang hoped that its life would not be in trouble, so he threw it some more gold drops.

In order to ensure that the fish could adapt to the fishing environment, he spread the gold drops into thousands of small dots.

After discovering the gold drops, the bluefin tuna became excited and tried hard to float up and down in the water, absorbing oxygen while getting the gold drops.

Ao Muyang is not sure whether he can feed this bluefin tuna. This is a problem that has not been solved in the world's fisheries so far. Only Japan has touched the edge of the technical difficulties and can probably complete the breeding.

However, the area of ​​these farms is not so large. Spain is also conducting bluefin tuna breeding experiments. The largest farm there is only 50,000 square meters.

50,000 square meters is not a small area, but Ao Muyang's fishery is 10 million square meters!

For the time being, this fish survived in the fishery. After swallowing all the gold drops it could find, it swam quickly in the sea.

Ao Muyang observed for a while and suddenly discovered a swimming pattern of tuna:

This fish is swimming after the solar oxygen generator. Its swimming route is like this. It swims from near an oxygen generator to near the oxygen generator next to it, and then continues to move forward, just like this, constantly chasing the oxygen generator to swim.

Seeing this scene, Ao Muyang couldn't help but smile. He had some confidence in the breeding of bluefin tuna.

The tuna was smarter than he expected, or maybe it was instinct. The fish quickly discovered that the water near the oxygen generator had more dissolved oxygen and a higher density. It swam along the route of the oxygen generator to get oxygen more easily.

And because the oxygen density in the waters around the oxygen generator is high, it can also slow down its swimming speed to rest in these places.

In this way, its activity route and life have become mechanical, but for fish, shrimps and crabs, this is not a problem. They only seek survival, not quality of life.
