Don't look at the modern aquaculture industry, any person can raise a few fish at home.

In fact, before the Han Dynasty, fish farming, including catching fish, was a very difficult thing.

At that time, there were no professional fishing tackle, and the fishing nets were very rough, and sometimes you could get three or four fish after a whole day's struggle.

After finally catching fish, there are few who can raise fish, so they can only use the method of stocking to raise fish.

Throwing fish into the pond depends on the will of God whether it is dead or alive.

There are no more elaborate techniques such as changing the water and increasing the oxygen in the water.

This is why in the Spring and Autumn Period and the Warring States Period, and even in the Qin Dynasty, many people who lived by the sea, rivers and lakes starved to death and did not eat fish.

It's not that they don't want to eat, it's that they really can't catch fish.

It was not until the middle of Emperor Wu of the Han Dynasty that someone compiled a book of "Tao Zhu Gong Fish Farming", which promoted the development of aquaculture.

Emperor Wu of the Han Dynasty himself also built a Kunming pond for fish farming.

In your spare time, you can also decompress by feeding the fish.

However, the Kunming pool consumed countless manpower, material and financial resources.

On this desert island, Tang Qi is the only one who has built a fish pond, and there seem to be a lot of sea fish in the pond.

This made Liu Che feel a little unbelievable.

But after thinking about it, this guy is also a fairy, isn't it common to build a fish pond to raise some fish?

"Mr. Tang, is your fish pond built with immortal arts?"

Liu Che asked Tang Qi for confirmation seriously.

Tang Qi said helplessly: "To build a fish pond, you need to use immortal arts, you can dig it with a shovel yourself, a simple batch." ”

"Dig it yourself?"

Liu Che scratched his head and said, "Can this one person dig it out?" And how do you get fish in a fish pond? ”

Tang Qi couldn't help laughing and said: "I want someone to dig with me, but the key is that there is no one on this island, so I can only dig by myself." ”

Liu Che wanted to say something, but Tang Qi interrupted: "Okay, Lao Liu, I can see it, you guy doesn't understand any common sense, don't ask, I'll take you directly to the fish pond to see you later." ”

"Okay!"

Liu Che nodded and continued to eat fries.

Foreign fast food such as french fries is still very attractive to first-time tasters.

Liu Che, Wei Qing and Wei Zifu ate two large bowls of fries one after another before rubbing their stomachs and stopping.

Eat all-you-can-eat french fries, and there is no one left.

"Mr. Tang, can we go and see the fish pond now?"

Liu Che asked eagerly.

Tang Qi shrugged his shoulders and said, "Let's go, I'll show you and increase your common sense!" ”

After speaking, Tang Qi took the lead in walking towards the east side of the wooden house, and Liu Che, Wei Qing and Wei Zifu hurriedly followed.

On this island where birds don't, in order to avoid being driven crazy by a boring life, Tang Qi specially raised a lot of animals and sea fish.

Among them, the project of raising marine fish took Tang Qi a lot of effort, and it was far from being as simple as he said.

The first is to dig a pool with a tool.

The pool is not large, only five or six meters horizontally and vertically, but the depth is about eight or nine meters.

After all, he wants to raise marine fish, not shallow water fish.

Secondly, two canals will be dug to connect to the sea.

One is for water inlet and one is for water out.

Both canals are usually sealed.

This will prevent some of the big ferocious guys from rushing into the pool and messing around.

Only when the water was changed was the two canals dug and a simple fence was used to block the part where the canal and the pool were connected.

Seawater pours in from higher intakes and out of lower outlets.

This completes a water change.

The whole project is difficult to say, and simple to say, but it did take a lot of Tang Qi's time and energy.

But in order to appear in front of people (pretending to be forced), Tang Qi deliberately said that the clouds were light and light.

When Liu Che, Wei Qing and Wei Zifu saw the fish pond, they were really shocked.

The water in the fish pond is very clear, and you can see the fish and lobsters swimming in the pond through the water, and there are many kinds and quantities of marine products.

"Don ...... Mr. Tang, this ...... How did the fish in this pool come from? ”

Liu Che stammered and asked Tang Qi.

The Kunming Pond that he spent a lot of money to build is probably only so much aquatic in it, but the area of the Kunming Pond is more than 100 times that of this fish pond.

There is no comparison between the two.

Tang Qi still pretended to be indifferent and said: "Most of these fish rushed in by themselves at high tide, and some of them were caught by me!" ”

Liu Che probably knew the situation at high tide, and he asked again, "Mr. Tang, how do you fish?" Why are you catching so much? ”

Tang Qi raised his eyebrows and said: "It's just to use a fishing rod to fish, string some fish food, find a place where the water is relatively gentle, and fish slowly!" ”

He fishes purely to pass the time, and he doesn't care if he catches it or not.

But even so, he still caught a lot of marine fish.

Liu Che was quite interested in the production of fishing rods and fish food, and continued to ask.

This time I asked Tang Qi's heart.

As a fishing enthusiast, it's so rare to meet a fan.

So, Tang Qi pulled Liu Che and talked for half an hour about how to make a fishing rod, how to make fish food, how to find a suitable area for fishing, and how to dig a fish pond.

Tang Qi said with his eyebrows fluttering, completely unaware that there was another person behind him who was silently recording with a paper and pen.

This person is naturally Wei Qing.

Liu Che said before that Tang Qi is a man among the immortals, and his true skills let Wei Qing learn from Tang Qi.

Wei Qing felt stupid, so he thought of this method.

The so-called good memory is not as good as a bad pen.

Wei Qing plans to record all the knowledge points that Tang Qi said, and when he returns to Chang'an, he will find someone to help sort it out, so that he can turn the ability of the immortals into the hands of the big man.

Half an hour later, after Tang Qi finished instilling knowledge in Liu Che, he began to instruct Liu Che and Wei Qing to open a canal to change the water.

At first, Wei Qing was a little reluctant to let Liu Che work.

After all, Liu Che is also the emperor of the Han Dynasty, and it is too bad to do this kind of rough work.

But Liu Che himself is quite willing.

He's been worrying about the country all along, but now he's finally free, and he just thinks it's fun to do anything.

It's a pity that Liu Che's level of work is really not very good, and he belongs to a typical handicap party.

If it weren't for Liu Che, Wei Qing would have been able to complete the water change in an hour alone.

With the addition of Liu Che, the working hours became an hour and a half.

This made Tang Qi couldn't help but laugh at Liu Che a few words.

Liu Che was cheeky and didn't take Tang Qi's ridicule seriously at all, but asked when he would have lunch.
