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

For the cultivation of seaweed, the people in the village are familiar with the road, and there is no need to teach, the big guys know what to do, and it is also easy for Ao Muyang.

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

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, and I heard that the kelp method is now used to grow giant algae. ”

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

"Actually, I don't know much about it, there's no way, we are uneducated, and we are coarse. Ao Qianwen said politely first, he pondered for a while and then said, "I see that people have done it, that is, they use plastic ropes to tie the young algae of the giant algae, and then, this rope has ropes at both ends with rope buckles, just find a reef on the bottom of the sea and tie it." ”

Ao Mupeng smiled: "That's not much more troublesome than our method?"

Ao Qianwen said: "You see that you have no culture, it is troublesome, but its rope can be adjusted in length, different seasons of light and water temperature are different, adjusting the length of the rope can keep the seaweed in a suitable position, so that it grows fast." ”

Ao Muyang also understands this method, but it is very difficult to operate.

He felt that it was not so troublesome to plant kelp in the sea outside the village, after all, the kelp seedlings he transplanted had good genes and had a higher utilization rate of sunlight.

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

Li Ji knows a more advanced method of cultivating macroalgae, called submersible raft farming, in which the floating raft is lowered underwater for the cultivation of macroalgae through the rope of the floating and rafting.

The principle of this method is the same as the submerged rope method mentioned by Ao Qianwen, because the giant algae is more sensitive to light, and the giant algae is always in the best water layer for breeding by often stretching and stretching the rope to promote the growth of the giant algae.

However, Li Ji provides a more efficient method by using a farming raft to grow macroalgae, and a batch of macroalgae seedlings are fixed to the raft, and then the raft is fixed to two adjacent breeding ropes by connecting ropes.

Thick ropes are tied with plastic floats, they are very buoyant, floating on the water surface, so that the raft needs to be how deep from the water surface, then adjust the length of the rope tied to the plastic float, so that the plastic float drives the raft to always be in the appropriate water depth position.

Li Ji and Su Penghui have a very hard relationship, they can contact the channel to provide these rafts to Longtou Village, and Li Ji also came up with an idea to let the Provincial Aquarium come out with this money as a subsidy for breeding manatees in Longtou Village.

Ao Muyang refused, there was no need for that.

Thousands of kelp trees were thrown into the sea, and they worked until the moon rose.

Li Ji said: "There are really a lot of giant algae planted today. ”

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

Ao Muyang said with a sluggish face: "No, right?"

"Don't listen to Lao 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 still underestimate the food consumption of the manatee species.

Indeed, after Li Ji contacted the Provincial Aquarium to invite them to transfer manatees to the turtle sanctuary for breeding, the director and secretary of the aquarium did not hesitate at all and immediately agreed to this request.

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

The manatee is spindle-shaped, similar to calfs, but they are longer and less energetic than whales, and when they are brought to the sea by boat, they stick to the surface of the water and do not move.

Ao Muyang asked curiously, "Aren't all manatees fat?" ”

The staff squeaked and didn't answer, they put down the manatee and left a bunch of documents and left.

Li Ji told Ao Muyang: "It's right for them to be thin, and it's only if they're not thin that they're the problem—if you have a toothache for half a year and can only eat feed for half a year, you can see if you're thin." ”

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

The adult manatee is two and a half meters long, and the young manatee is like a half-grown piglet, and it is estimated that it must weigh 180 pounds.

There was a baby manatee in the arms of the female manatee, and the female manatee turned over and stuck to the water, and her two fat pectoral fins opened to protect the baby manatee, like a cradle in the water.

The other manatee was in a much more awkward position, with its elders ignoring it and lying under the surface of the water.

Ao Muyang felt that the condition of this little manatee was not very good, it had been fluttering, and it looked very energetic, but in fact, the skin was rough and dull, and the eyes were also very dull, more like a return to the light before death.

So he carried the little manatee into the boat to take a closer look, but not long after the little manatee came aboard, its eyelids drooped a few times, and then it began to weep......

"Brother-in-law, you scared it, you saw it crying like an ugly child of a hundred pounds. Lu Wuxian hurriedly said.

Ao Muyang gave the little manatee a little gold to eat, and he said disdainfully: "No culture, this is not crying, what it flows out is not tears, but eye protection, this thing is salty, you taste it." ”

He twisted a drop and stuffed it into Lu Wuyi's mouth, Lu Wuyi was stupid, he looked at Ao Muyang in a daze, and then lay on the boat and began to vomit: "Bah, vomit, it's disgusting!"

Li Ji sighed: "This child weighed 100 catties when he was born, they were starved and thin, and they didn't grow up much, otherwise when they were supported by fat, they would have weighed 200 catties." ”

Ate two gold drops in a row for the little manatee, Ao Muyang fed a little gold drop to each of the other manatees, and the manatees ate the gold drops for about ten minutes, and then they were no longer lifeless, and finally began to move.

Except for the cow with the calf in her arms, the other adult manatees dived underwater.

Manatees like to dive, but they breathe with their lungs, and after a period of diving, they have to put their nostrils out of the water to breathe, and in general, adult manatees can dive in the water for more than ten minutes.

They have a lid on their noses, which opens to breathe when they are out of the water, and when they are back in the water, the lid closes, which is almost the most dexterous part of their body.

It's interesting to watch manatees swim, they are clumsy, they swim very slowly against the surface, and they seem to trip over them as if the water can trip them, and they tend to start turning their heads in the water as they swim.

Of course, they are also slow to somersault.

After a while, the manatees begin to eat, and they dive down, opening their mouths to the seaweed and gobbling it up.
