Ao Muyang wants to catch bluefin tuna, even if he only catches one female, as long as it is a female with fish roe, that fish can give birth to a fishing ground.

Bluefin tuna are very raw, a 100-kilogram fish can produce 5 million seeds a year, and they themselves can live for 30 years!

After these fish roe hatch into fish, it is impossible for them all to grow up, in fact, the survival rate is less than 1 in 10,000 in a year and less than 1 in 100,000 in 100,000 years.

Yellowfin tuna can grow up to two meters, albacore tuna can grow up to one meter four, bigeye tuna can grow up to two meters four, and bluefin tuna is even more exaggerated, with all of them growing up to four meters!

However, when they first hatch, they are the size of seaweed duckweed, and as they grow, they are constantly hunted by other marine life.

In other words, if the tuna grows up, it is a lot of RMB, and if it doesn't grow up, it is the ration of a group of fish, shrimp and crabs.

It can be sold for money and can be used as natural feed, which is too precious for the fishery!

It's a pity that Ao Muyang didn't have this luck.

He threw two gold drops in a row, attracting a bunch of fish, but not the bluefin tuna.

After all, it was too late for him to release the golden drop, and the tuna was long gone, and the allure of the golden drop could not be without a distance limit.

Because the tiger was guarding the side, the fish and shrimp lured by the golden drop cowered and did not dare to approach, but only dared to salivate from a distance.

Ao Muyang also salivated, he looked at the surrounding seabed, wanting to see if the tuna school would come back.

Unfortunately, they didn't come back.

Seeing this, he waved his hand happily, and the tiger was still eyeing the golden drop, and when he saw this, he immediately came to a hungry tiger to pounce.

As soon as the tiger left, the other fish came to grab the food, and they scrambled to swim to another drop of gold.

said that it was too late, and then quickly, a torpedo-like figure 'swished' down from the sea above, with a round body and a crescent-shaped fish tail, Ao Muyang was stunned!

A bluefin tuna!

Not all the tuna left, one fish may have returned, or it may have left the group at first, but it was also attracted by the droplets.

But it has been wandering on the surface of the seawater, and Ao Muyang has been paying attention to the bottom of the sea since staying in the seawater, and has not looked up, so he has not seen this fish.

As soon as the bluefin tuna came out, Ao Muyang immediately waved his finger up.

When the general received the order, his big tail flicked off a wild current, and with a 'whirl' sound, he broke through the sea water barrier and swam quickly.

The tuna wants to run after eating the gold droplets, but how can it be so easy?

And because the tiger is in the bottom layer of the sea this time, when it rushes up, the tuna can't dive if it wants to escape, and it has to continue to swim in the upper layer of the water.

It swam quickly in the seawater, and there was a figure chasing harder behind, and that was Little Brother Huang!

Little Brother Huang was almost angry, grinning and chasing after him like a hound: there are two gold drops in the water, one drop is a tiger's, it has no opinion, and the other drop should be its!

The bluefin tuna ate this little bit of gold, but it made Huang Xiaodi angry, and he chased harder than the tiger.

Even with additional interceptions, the bluefin tuna was finally hit by the tiger......

This bluefin tuna is about a meter and a half long, which is simply not enough to see in front of a tiger of more than four meters, and as soon as the tiger approaches it, its speed begins to slow down.

When the tiger swims, the turbulence caused by the body rubbing against the sea water is very strong, and the balance of the bluefin tuna is affected, so it is natural that it cannot swim fast.

After the tuna was hit, it rolled in the water again and again, Ao Muyang reversed Jin Dan and chased after it, and caught the tuna in his hand.

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

As we all know, the respiratory organ of fish is the gills, whether swimming or stationary, their gills are always open and closed, in order to absorb dissolved oxygen from the water and release carbon dioxide in the body.

However, tuna use percussive breathing, which does not actively absorb dissolved oxygen, and needs to be breathed by hitting the water body in the water to let the seawater flow through the gills and leave dissolved oxygen behind.

This is where the problem arises, tuna must swim constantly if it wants to breathe, and once it stops, it will lack oxygen and cause suffocation.

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

Therefore, the bluefin tuna he caught must not 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, and if the fish came to his senses, he would never be able to catch it with his strength.

So he dragged the gills of the fish onto the motorboat, accelerated all the way back to the fishing grounds, and threw the fish over the net.

The hapless bluefin tuna was fooled, and it floated dizzily in the water, its body twisting left and right, crooked, as if it were drunk.

Even so, it is trying to swim, and if it doesn't swim it will suffocate!

Ao Muyang hoped that there would be no problems with its life, so he threw it a little bit of gold.

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

When the golden drops are found, the bluefin tuna is energetic, trying to float up and down in the water, and get the golden drops while absorbing oxygen.

Ao Muyang is not sure if he will be able to feed this bluefin tuna, which is a problem that has not been solved in the world's fishery industry so far, and only Dongying has touched the edge of the technical problem and can probably complete the cultivation.

However, none of these farms are that large, and bluefin tuna trials are also being conducted in Spain, where the largest farm 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 time being, the fish survived the fishing grounds, swallowing all the gold drops it could find, and then swimming quickly in the sea.

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

The fish is swimming after the solar oxygen generator, and its swimming route is like this, swimming from near one oxygen generator to the oxygen generator next to it, and then continuing to swim after the oxygen generator.

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

The tuna was more clever than he expected, or perhaps instinctively, and the fish soon discovered that there was more dissolved oxygen in the water near the oxygen generator, and that it could more easily obtain oxygen by swimming along the path of the oxygen generator.

And because the oxygen density in the waters around the oxygen generator is high, it can also reduce its swimming speed in these places and take a break.

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