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

Bluefin tuna is very good. A fish weighing 100 kilograms can produce 5 million seeds a year, and they can live for thirty years!

After these fish roes hatch into fish, they cannot grow all of them. In fact, the survival rate of one year is less than one ten thousand, and the survival rate of ten years is less than one hundred thousand. Don’t think they can grow very big:

Yellowfin tuna can grow to two meters, albacore tuna can grow to one meter four, big-eyed tuna can grow to two meter four, and bluefin tuna is even more exaggerated, and there are all four meters long!

However, when they hatch, they are the same size as seaweed duckweed. During their growth, they will be constantly hunted by other marine organisms.

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

It can be sold for money and made of natural feed. This thing is too precious for fishing grounds!

Unfortunately, Ao Muyang did not have this luck.

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

After all, it was too late when he released the Golden Drop, and the tuna had long disappeared. The Golden Drop's temptation could not be without a distance limit.

Because the tiger was guarding the side, the fish and shrimps tempted by the golden drops were timid and dared not approach them, and only dared to look at them from a distance.

Ao Muyang also looked at it with covetous eyes. He looked at the seabed around him and wanted to see if the tuna school would come back.

Unfortunately, they did not come back.

Seeing this, he waved his hand in vain. The tiger was still eyeing Jindie. Seeing this, he immediately came a hungry tiger to rush to eat.

As soon as the tiger left, the other fish came to grab food, and rushed upstream to another little golden drop.

At that time, a torpedo-shaped figure rushed down from the sea above. Ao Muyang was stunned with a round body and crescent-shaped fish tail!

A bluefin tuna!

Not all tunas left. One fish might return, or maybe it would leave the fish group at first, but it was also attracted by the golden drop.

But it has been wandering on the surface of the sea. Ao Muyang stayed in the sea and kept paying 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 finger.

The general got the order, and his big tail swung his way up a wild stream, and he rushed away the sea water with a "huh" sound and wandered around quickly.

The tuna still wants to run away after eating the gold drop, but how is it that easy? The tiger is eyeing it!

And because the tiger is under the sea this time, when it rushes upwards, the tuna cannot dive if it wants to escape, and it has to continue swimming towards the upper sea.

It swims quickly in the sea water, and there is a figure who is chasing behind harder, that is Little Brother Huang!

Brother Huang was almost angry and grinned and chased him like a hunting dog: two golden drops in the water, one drop is from a tiger, it has no objection, the other drop should be from it!

The bluefin tuna ate this little gold drop, which made Xiaodi Huang very angry. It chased her harder than a tiger.

After further interruption, the bluefin tuna was finally hit by a tiger...

This bluefin tuna is about one and a half meters long and is not enough to see in front of a tiger over four meters. When the tiger approaches it, its speed begins to slow down.

When a tiger swims, the turbulence caused by its body friction against the sea water is very strong. The balance of the bluefin tuna is affected, so it will naturally become unsustainable.

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

After the fish was caught, he still felt embarrassed and it was difficult to deal with!

As we all know, the respiratory organs of fish are fish gills. Whether swimming or still, their gills are always open and closed, with the purpose of absorbing dissolved oxygen from water and releasing carbon dioxide in the body.

But tunas use impact breathing. They do not have the ability to actively absorb dissolved oxygen. They need to hit the water body in the water, allowing sea water to flow through the fish gills, leaving dissolved oxygen to breathe.

This problem arises. If the tuna wants to breathe, it has to swim continuously. Once it stops, it will lack oxygen and cause suffocation.

According to Ao Muyang's knowledge, bluefin tuna must swim at a speed of at least 65 cm per second to hit enough sea water to obtain oxygen.

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

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

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

This unlucky bluefin tuna will be fooled by it. It floats in dizzyness in the water, twisting its body left and right, crooked, as if it is drunk.

Even so, it is swimming hard, and if it doesn’t swim, it will be suffocated!

Ao Muyang hopes that his life will have no problems, so he gives it a little more gold.

In order to ensure that the fish can adapt to the fishing ground environment, he spread the golden drops into hundreds of small dots.

Discovering gold drops, the bluefin tuna came to its strength, and tried hard to dive in the water, absorbing oxygen while obtaining 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 fishery so far. Only Japan has touched the brink of technical problems and can probably complete breeding.

However, these farms are not that large in size. Spain is also conducting bluefin tuna farming experiments, and the largest farm there is only 50,000 square meters.

The area of ​​50,000 square meters is not small, but the fishing ground in Ao Muyang is 10 million square meters!

For the moment, the fish survived in the fishing ground. 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:

The fish was swimming chasing the solar oxygen generator. Its swimming route was like this: swimming from near an oxygen generator to near the next oxygen generator, and then continued to move forward, and continued to chase 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.

Tuna was smarter than he expected, or it was instinct. The fish soon discovered that the water near the oxygen generator dissolved more oxygen and had a higher density. It swam along the oxygen generator route and could obtain oxygen more easily.

Moreover, because the oxygen density in the waters around the oxygen generator is high, it can also reduce the swimming speed and rest in these places.

From this point of view, its activity route and life have become mechanical, but for fish, shrimp and crabs, this is not a problem. They only seek survival, not quality of survival.
