The cucumber vines on the shelves are still flourishing, and the verdant cucumbers hang down from the vine leaves, verdant and dripping.

Five stubbles of cucumbers have been harvested, and it seems that several stubbles can be harvested, and a stubble of cucumbers can now bring a stable and consistent half a penny, and another five stubbles can also bring Li Xiao seven or eight pieces of money.

But now seven or eight yuan is nothing in Li Xiao's eyes, although compared to the tenant farmers in the family, this is already a huge amount of money.

During this time, the spiritual spring seemed to have grown a little, the water was clearer and seemed to be deeper, and the group of small fish fry I saw a few days ago had also grown up a lot.

He looked closely, and the fry didn't seem to be carp. It's not a carp, the royal surname of the Tang Dynasty is Li, and Taoism is respected, but Taoism respects carp as Chihun Gong, and does not eat carp at all. Although it is said that the imperial court does not directly prohibit the people from eating carp, Emperor Xuanzong of the Tang Dynasty will officially issue an order to ban carp fishing.

However, carp sales in the market have been somewhat affected.

This group of fry does not seem to be more than one kind of fish, it seems that there are grass carp and chain fish, and even big-headed fish and herring, well, isn't this the four big fish of later generations?

It is said that the production of the four major fish is related to the Tang Dynasty. Before the Tang Dynasty, the most widely cultivated was carp, and later because of the reason that Li Tang banned carp fishing, fishermen had to engage in the breeding of other fish species, and slowly there were four major freshwater domestic fish species of herring, grass carp, silver carp and bighead carp.

The reason why there are four big fish, in fact, is also related to the living habits of these four kinds of fish, silver carp is also called silver carp, like to move in the upper layer of the waters, love to eat green algae and other phytoplankton, and fathead fish has a large head, so it is called fathead fish, also called silver carp, generally inhabits the pelagic layer of the waters, eats protozoa, daphnia and other zooplankton.

Grass carp like to live in the middle and lower layers of the water, swallow the vegetation in the water and excrete it, and wait for the feces to breed microorganisms before eating, filtering the micro-raw fish in it.

The herring likes to live at the bottom of the water, eating snails, clams, mussels and other mollusks, fishermen have given birth to the living habits of these four kinds of fish, and they are chaotically raised, which greatly improves the production of fish, and gradually forms the origin of the four major fish.

These four kinds of fish are relatively easy to raise, and they are easy to grow, especially those that can grow very large, such as fathead fish, which can grow to seventy or eighty catties.

It was not easy for the ancients to raise fish, and the most difficult thing was that the fry could not be artificially reproduced, so they had to rely on the fish spawning grounds in the rivers to catch the fry. Especially in areas such as Guanzhong, there are fewer artificial farms with river water, and Guanzhong is the capital of the Tang Dynasty, which is densely populated and has high consumption capacity, which leads to a large market, but a small supply, and fish has not been cheap.

Especially in Chang'an City, fresh fish is in short supply.

If Li Xiao can raise fish in Lantian and then find a way to transport live fish to Chang'an to sell, it will be a steady stream of money.

Coming out of the space, Li Xiao decided to dig a fish pond, since he had found such a good way to make a fortune, there was no reason not to get it. In any case, this characteristic of breeding should have a better way out than the traditional tenant land rent.

When it came to doing it, Li Xiao found Dr. Zhao and Mr. Yang, the two of them are now the elders of the family, and there is an old man in the family who is like a treasure, they are experienced, and they can always provide a lot of useful advice when discussing with them.

"I plan to dig a pond to raise fish," Li Xiao got straight to the point, there is a large depression on the side of our family's Blue Creek, which has been abandoned because it is prone to waterlogging, and I think it is just right to use this depression to rectify it and dig it into a pond to raise fish. ”

"It's a low-lying place, the water is difficult to drain, and it's barren all year round, so if you dig a pond to raise fish, it's okay. However, we have never raised fish, and without this experience, can we raise fish? "Mr. Zhao is very familiar with Lijiazhuang, and he is very familiar with the land that Li Xiao said, but he is really inexperienced in fish farming, and he also finds it difficult.

After all, I still haven't raised fish, and this is originally a mountainous area, in the belly of the northern foot of the Qinling Mountains, it is difficult to transport some things out, let alone raise fish.

You can't raise fish, and finally dry the fish and sell it, in that case, you won't be able to sell it for money.

Because there is a blue creek nearby, everyone usually eats less fish, but they are all caught in the stream, all wild fish, and no one has ever raised them.

I've seen raising cattle, horses, pigs, and chickens, but I really haven't raised fish.

"In fact, fish farming is quite simple, get fish fry, and then you don't have to manage it, just occasionally throw some grass, dung or something."

"Fish still eat dung?" Mr. Zhao was surprised.

Li Xiao didn't know whether the fish ate dung or not, but when he was in the countryside before, he saw other people's fish farmers splashing dung into the pond, and he didn't know whether the specific role was to raise grass or feed fish. Anyway, the grass has to be needed, and the water has to be alive.

Mr. Zhao stroked his beard, "I just remembered that San Lang has traveled all over Jinghan and Jiangnan in the past five years, and he has probably seen a lot of water towns over there." ”

Although Yang Dayan is from the south of the Yangtze River, he is not good at fish farming, and there are fewer fish farmers in the Jiangnan water towns, so it is good to fish directly in the rivers and lakes. Even on the southeast coast, there is also direct fishing in the sea, all kinds of dried fish and shellfish Yang Dayan has not eaten less before, the taste is not very good, but it is cheaper.

Li Xiao was ambitious, professed to have experience and technology, and quickly convinced the two.

After all, it doesn't take much to dig a fish pond, anyway, the tenants in the village borrowed the grain of the Li family, and now it is still empty, just let them dig the pond, which can be regarded as the borrowed grain.

The fish pond is wasteland, and it does not occupy good land, whether it can be successful, then it will be said, even if it is not successful, it does not cost much, you can give it a try.

"When the time comes, you can also plant some lotus root in the fish pond, and you can also plant taro on the edge of the pond, and use pond mud to grow taro, which is fat, and there is water to water in the fish pond, killing two birds with one stone."

Lotus root and taro can be used as both vegetables and grain, and if this thing does not occupy an area, the income will be in vain.

"Dig a two-acre fish pond first, and if you raise it well this year, dig a few more ponds next year." As soon as Li Xiao opened his mouth, it was two acres, "Inform the tenants, if you are willing to come to dig the pond, we will pack two meals a day and give two liters of millet." ”

The wage of two liters of corn a day is already very low.

But according to Mr. Zhao's words, it is the middle of winter, and it is already good to be idle anyway, and it is good to be able to earn two meals and take home two liters of corn.

"It's cold right now, and there's no water in that depression, so it's just the right time to drain the water and dredge the embankment."

The fields are now freezing hard, but the situation is much better in the depression because there is still some water. On a sunny day, it is suitable to start work, or wait until next year's spring after the rain is too much, the rain is continuous, and the depression is full of water, but it is difficult to get it.
