American manatees, also known as West Indian manatees, live in warm waters of the Atlantic Ocean and usually live in shallow seas and estuaries. They move slowly and have fewer numbers. They are endangered species on the Red Book of Animal Protection.

During the Spring Festival last year, the Mexican government delegation brought a herd of small manatees to China, including two adult males, four adult females and four small manatees.

You know, there are only a few thousand manatees in existence. Mexico sent ten people at a time, which was a big deal. It triggered strong protests from the American animal protection organization, believing that Mexico had made no limits to please China.

But Mexico also has its own reasons. First, these manatees live in their bays and have nothing to do with Americans, and they don’t eat your American bread; second, they want to trade manatees for pandas.

Americans also like pandas. Many cities there hope to introduce these furry stupid brothers. So when they learned about Lao Mo's purpose, they shut up. Then they waited and saw to see if Lao Mo could exchange the pandas back.

As a result, they were disappointed. China did not agree to give it to Lao Mo panda because after field investigation, experts from the panda nature reserve believed that the local area did not have the ability to breed pandas.

Of course, this is all off-topic. In short, China accepted ten manatees and sent them to the provincial marine animal breeding area of ​​Hongyang for breeding.

"The question is, manatees are one of the most powerful herbivorous mammals in the ocean. They eat a lot of food and the aquatic plants they can eat every day are quite 5% to 10% of their weight. Do you know what the average weight of adult manatees is?" Li Ji asked.

Ao Muyang touched his nose and said, "I don't know, it costs at least six or seven hundred kilograms, right?"

"One thousand kilograms!" Li Ji stretched out his index finger, "They can eat up to one hundred kilograms of aquatic plants and seaweed every day!"

The manatee eats grass very hard, like a carpet, with his mouth inserted on the bottom of the sea, and then ate it piece by piece, known as a weeder in the water.

In certain tropical and subtropical areas where aquatic plants are plagued by aquatic plants, raising sea manatees is very useful. In those places, aquatic plants hinder power generation, block rivers and canals, hinder navigation, and also bring filariasis, encephalitis and schistosomiasis to humans. Removing aquatic plants is a headache in the local area.

For example, there is a kind of aquatic plants in Africa called aquatic hyacinths. It was once 1,600 kilometers above the Congo River. There was a river channel spreading and growing and blocking, and even small boats could not pass. Local residents were forced to leave their hometowns because they could not transport food.

To solve this social crisis, the local government spent 1 million US dollars to sprinkle herbicide along the river. Only two weeks later, the aquatic plants grew twice as much. Later, the local government put two manatees in the river, and this problem was solved.

From this we can see how much demand for aquatic plants is.

Two manatees can solve the problem of water and grass flooding in a river channel of the Congo River, and there are ten manatees in the aquarium. If necessary, they are ten weeders. If there is no problem, they are ten big eaters.

In fresh water, manatees eat aquatic plants, such as water hyacinths; in salt water, they eat most seaweeds and seaweeds and are not picky about food.

Even so, the aquarium was eaten by them. Their appetite was too large, and they all day long, and they were shit, as if they were not sleeping.

The aquarium itself does not have aquatic plants and seaweeds, so they have to buy these things. The aquarium funding is limited and all the funds cannot be spent on manatees.

As a result, manatees became a drag on the breeding area. Due to funding issues, the aquarium logistics could not feed their fresh seaweed, so they used feed instead.

This problem arises. Everyone knows what China’s feed is going on. People have problems with what people eat, let alone animals eat. Manatees eat feed and then start to get bored.

By now, three of the ten manatees have died, one adult male manatee and two small manatees have died. The other seven are also many problems, and Li Ji and other relevant experts have been invited to solve the problem for them.

After saying that, Li Ji began to complain: "The main problem of these manatees is oral problems. Oral problems are easy to solve for other animals, but manatees are not good. Their oral structure is special and they lose teeth all their lives. Every once in a while, new teeth grow out to lift the old and worn teeth. As a result, the problem is now that new teeth have to grow outward and the old teeth do not loosen, so that new teeth cannot grow out. They will hurt so much that they can't eat and drink all day long. How can they survive?"

Ao Muyang asked: "Didn't you just say that they were a problem with eating feed? Why is it related to their teeth again?"

Li Ji sighed: "One meaning, manatees eat grass not only eat tender leaves, but also eat grass roots. Grass roots are very tough, so they have to use their teeth to grind, stir and eliminate them. This is a difficult process. The molars of other animals cannot withstand this grinding. The reason why manatees can withstand it is because they have a lifelong trick of losing teeth, and new teeth keep coming out and pushing out worn old teeth throughout their lives."

After hearing his explanation, Ao Muyang understood that the manatee ate feed every day and had less teeth worn out. Even when new teeth were released, it was still very strong, so it would be difficult for new teeth to eject the old teeth.

"In addition, those feeds also have problems, including various additives and hormones. After eating them, the manatee always has health problems. Alas, it is difficult to solve internal and external troubles," Li Ji said helplessly.

Ao Muyang squatted on the ground and thought about it, and said, "Old man, it's actually very easy to solve it. You can ask the provincial aquarium to send the manatees to me. Look at how much seaweed is in our sea? Just let them eat it with great energy."

Li Ji said: "I really thought about this method, but it is not reliable. First, the aquarium will not put gifts from foreign friends into the folk. Second, I am also for the village. Although there are many seaweeds in this sea, it is a little bit for the seven manatees. In their hometown, they eat giant algae!"

Ao Muyang said: "There is no problem with giant algae. I'll just transplant some giant algae."

There are really many giant algae in the Brick Island Fishery. The reason why Ao Muyang has not transplanted it to the waters outside the village is because it is unnecessary and he is worried that the growth of too fast and too much will lead to a decrease in the ornamentality of the ocean.

After all, the charm of the ocean lies in its vastness and clarity. If a tourist sits on a boat and looks down, he will see that the sea is full of dense seaweed, it will not be beautiful.

Li Ji snorted: "It's not that simple, young man."
