Golden Fishing Village

There were a lot of bricks and stones left over from previous road construction in the village, and Dalong Mountain is also rich in stones, so when Ao Muyang brought the giant algae seedlings back, the villagers could start the work with ropes.

When it comes to things like planting seaweed, the people in the village are very familiar with it and don't need to be taught. Everyone knows how to do it, which is easy for Ao Muyang.

Ao Qianwen was well-informed and recognized it at a glance as a giant algae seedling.

He said: "Village chief, our method of tying stones and throwing them directly into the sea is too primitive. This method has long been eliminated. I heard that the submersible rope method is now used to grow macroalgae."

"What is the hidden rope method?" Ao Mupeng asked as he skillfully tied the rope to the stone.

"Actually, I don't know much about it. I can't help it. We are uneducated and rude." Ao Qianwen said politely at first. He thought about it for a while and then said, "I've seen people do it before. They used plastic ropes to tie up giant pigs. The larvae of the algae, and then, the rope has buckles at both ends, and it can be tied to the rocks on the seabed. "

Ao Mupeng smiled and said: "Is that much less troublesome than our method?"

Ao Qianwen said: "You see, you are uneducated, it is troublesome, but the length of the rope can be adjusted. The light and water temperature are different in different seasons. Adjusting the length of the rope can keep the seaweed in a suitable position, so that it will grow longer." Be quick."

Ao Muyang also knew this method, but it was very laborious to operate.

He feels that planting macroalgae in the sea outside the village does not have to be so troublesome. After all, the macroalgae seedlings he transplanted have good genes and can utilize sunlight more efficiently.

Later, I saw him leading people to plant giant algae, and Li Ji and Su Pengyu brought their students to help.

Li Ji knows a more advanced method of growing macroalgae, called submersible raft culture technology, which uses a rope connected to the raft and the raft to sink the floating raft underwater to cultivate macroalgae.

The principle of this method is the same as the rope-diving method mentioned by Ao Qianwen. It is because macroalgae are relatively sensitive to light. By frequently extending and contracting the rope, the macroalgae is always in the optimal water layer for cultivation, thereby promoting the growth of macroalgae.

However, this method provided by Li Ji is more efficient. It uses a breeding raft to grow macroalgae. A batch of macroalgae seedlings are fixed on the raft, and then the raft is fixed to two adjacent breeding ropes through connecting ropes.

Plastic floats are tied to the thick rope. They are very buoyant and float on the water. If the raft needs to be as deep as the water surface, adjust the length of the rope tied to the plastic floats so that the plastic floats can drive the raft all the time. At the appropriate water depth.

Li Ji and Su Penghui had a close relationship. They were able to contact Longtou Village to provide these rafts. Li Ji also came up with an idea to ask the Provincial Aquarium to provide the money as a subsidy for Longtou Village to breed manatees.

Ao Muyang refused, it was not necessary.

Thousands of giant algae plants were thrown into the sea, and they worked until the moon rose.

Li Ji said: "There are so many giant algae planted today."

Su Penghui said: "When they grow up, I think they can feed the manatees several times."

Ao Muyang said with a dull expression: "Isn't it?"

"Don't let Old Su scare you." Li Ji comforted him and said, "These are enough for manatees to eat for a month."

After listening to their words, Ao Muyang felt that he might have underestimated the appetite of manatees.

Indeed, after Li contacted the Provincial Aquarium and invited them to move the manatees to a sea turtle sanctuary for breeding, the director and secretary of the aquarium did not hesitate at all and immediately agreed to the request.

And they were very fast. Li Ji contacted the Provincial Aquarium the next day after planting the giant algae seedlings in Ao Muyang, and the next day, all seven manatees were delivered.

American manatees have spindle-shaped bodies and look a bit like small whales. Their bodies are longer and not as energetic as whales. After being brought to the sea by ship, they stick to the water and remain motionless.

Ao Muyang asked in confusion: "Aren't all manatees fat? They are a little thin."

The staff didn't answer. They put down the manatee and left a pile of information before leaving.

Li Ji told Ao Muyang: "It's right for them to be thin, and there is a problem if they are not thin - if you have a toothache for half a year and can only eat feed during this half year, let's see if you are thin."

Five of the seven manatees are adults and two are calves.

An adult manatee is two and a half meters long, while a baby manatee is about half a piglet and probably weighs 180 kilograms.

There was a calf in the arms of the mother manatee. The mother turned over and clung to the water, with her two fat pectoral fins spread out to protect the calf, like a cradle in the water.

The situation of the other calf was much more embarrassing. Its elders ignored it and just hid under the water to lay its body.

Ao Muyang felt that the calf's condition was not good. It kept flapping its edges and looked very energetic, but in fact its skin was rough and dull, and its eyes were dull, more like a flashback before death.

In this way, he carried the little manatee onto the boat to observe it carefully. As a result, not long after the little manatee got on the boat, its eyelids drooped a few times, and then began to cry...

"Brother-in-law, you scared it. Look at it crying like an ugly child weighing a hundred pounds." Lu Wuji said quickly.

Ao Muyang gave the little manatee some golden drops to eat, and he said disdainfully: "You are uneducated. This is not crying. What it sheds is not tears, but eye protection. This thing has salt. Here, try it. taste."

He twisted a drop and stuffed it into Lu Wuyi's mouth. Lu Wuyi was dumbfounded. He looked at Ao Muyang blankly, then lay on the boat and started to vomit: "Bah, bah, bah, vomit, it's so disgusting!"

Li Ji sighed, "This child weighed less than 100 kilograms when he was born. They were starved and thin, and they didn't grow much. Otherwise, when they had fat, they would have weighed 200 kilograms."

After feeding the little manatee two drops of gold in a row, Ao Muyang fed the other manatees a little gold drops. After eating the gold drops for about ten minutes, the manatees no longer looked lifeless and finally began to move.

Except for the mother cow holding the little manatee in her arms, the other adult manatees dived underwater.

Manatees like to dive, but they breathe with their lungs. After diving for a while, they have to expose their nostrils to the surface of the water to breathe. Generally speaking, adult manatees can swim underwater for more than ten minutes.

They have a cover on their noses. When they are exposed to the water, the cover will open to breathe. When they return to the water, the cover will close. This is almost the most agile part of their body.

It is very interesting to watch manatees swim. They are very clumsy and swim very slowly close to the surface of the sea. It seems that the water can trip them up, and they often start to turn over in the water while swimming.

Of course, their somersaults are also very slow.

After a while of activity, the manatees began to eat. They dived down, opened their big mouths and began to devour the seaweed.
