When he heard that the thornball sea urchin was delivered, Butler rushed back in a small boat with interest. After jumping onto the dock, he began to shout: "Qin, Qin, where is my sea urchin?"

Qin Shiou twitched the corners of his mouth and took him onto the transport ship, asking him to check out the round small thorn balls staying in the breeding box.

Butler pinched one with a clip and took it to his eyes. His eyes were simple, as if the sculptor was admiring a piece of good marble.

After watching for a while, the bearded uncle exclaimed, "Oh, God, this is the pineapple sea urchin? Do Chinese and Japanese like to eat this thing? It looks so ugly and cute."

Qin Shiou's corners twitched violently, Bill pulled him and asked in a low voice: "This is the guy you mentioned who is very good at identifying sea urchins? Really, how can you say it? You can't tell from the outside."

Facing Qin Shiou's gloomy gaze, Butler laughed loudly. He patted Qin Daguanren on the shoulder and said, "Okay, okay, relax, I'm just a joke. You must know that when I was fourteen, I followed my uncle to your North China Sea to fish sea urchins."

Butler patiently observed the breeding box, then nodded and said, "No problem, it is indeed a pineapple sea urchin. It is very active and has a beautiful job. It is rarely seen such a good product now."

After hearing this, Bill showed a proud look on his face and said, "It's not bad, I got it through some secret ways."

Butler and Bill shook hands and said to Qin Shiou: "You made a friend with energy. The sea urchin market is too chaotic now. A few days ago in Japan, I heard that Singapore farms now like to use southern purple sea urchin as light raptor ball sea urchin. Some Japanese seafood merchants suffered a loss."

Sea urchin is one of the traditional delicacies in East Asian countries. It is precious as the eight treasures of the ocean. The edible part of this thing is sea urchin cream, which is rich in nutrition, delicious, and has a good nourishing and strengthening effect.

Foods such as salted sea urchin, alcoholic sea urchin, chilled sea urchin, steamed sea urchin and sea urchin sauce processed with sea urchin paste are even more popular among the high-income class.

As East Asian countries increase their influence in the world, and East Asian indigenous people such as Chinese, Japanese, Korean and other East Asians have come to all over the world. Sea urchin cream is slowly becoming popular in the international market.

The light pineapple sea urchin cream produced in Northeast China is the world's top sea urchin product. It is also very popular in Europe and the United States, and the supply is in short supply. Last year, Prince William's wedding ended, and there was light pineapple sea urchin cream at the wedding banquet.

The southern purple sea urchin that Butler said looks similar to the pineapple sea urchin, and its appearance is purple-black. Therefore, some merchants often use them to pretend to be pineapple sea urchin.

In fact, the southern purple sea urchin is also a treasure, but it is not as good as the pineapple sea urchin. The former is cultivated in tropical waters, while the latter is an indigenous person in cold waters, generally the same species. The value of the cold waters is higher than that of tropical waters.

The sea urchins sent by Bill are also sea urchin seedlings, scientifically called Child Sea urchins. They have particularly high requirements for water quality at this stage. Of course, the water quality of the Daqin Fishery is almost the best in North America and must meet the requirements.

Sea urchin breeding is more troublesome than fish, shrimp and crab farming. You need to put them on the seedling board first, instead of throwing them directly into the sea and then ignore them. If it is too easy to use the natural stocking method, it is estimated that the number of sea urchins will float on the sea surface in a few days. Of course, it is dead.

Bill was so happy to cooperate with Qin Shiou. He was very capable and reliable in doing things. This time he came here to prepare all the tools and techniques for sea urchin breeding, so Qin Shiou just applied it directly.

The tools needed in breeding are seedling plates and frames. The seedling plates are used to collect abnormal sea urchin, and can also be used as the attachment matrix for the cultivation of sea urchin and provide diatom bait for the adherence of abnormal seedlings. The frames are mainly used to assemble seedling plates to make them easier to operate and manage.

Among them, the seedlings are non-toxic transparent polyvinyl chloride corrugated boards, with a length of half a meter, a width of forty centimeters, and a thickness of half a centimeter. There are undulating ripples on the board, with a wave height of about 1.5 centimeters.

There are two types of frames for assembling seedlings and folding. Each frame can assemble 20 seedlings and seedlings.

Bill brought a folding frame. He asked the worker to open a demonstration and said, "Look, whether placed horizontally or vertically, in this frame, the seedling plates are not easy to fall out. Moreover, the area of ​​this frame is large, the spacing between the seedling plates is large, and the plates are not easy to overlap, which is more suitable for sea urchin seedling cultivation."

If you check everything is fine, you have to invest in breeding.

Ordinary fishing grounds are good breeding ponds, and Daqin Fishing Ground has ready-made ones, that is, engineered breeding ponds, which are more advanced and have a larger area.

There were prawns in the breeding pool before. Qin Shiou asked the fishermen to open the gate and put the prawns into the fishing ground. Anyway, he had already inputted enough sea god energy to the prawns, and the female shrimps should lay eggs, and now there is no problem entering the ocean.

After packing out the breeding pool, Bill directed the workers and fishermen to put frames into them, then set up the seedling boards on them, and finally put the urchin on them.

A piece of seedling harvesting board can breed about forty sea urchins. They are small now and will have to be divided into seedlings when they grow up, so they can be cultivated more.

When the sea urchins were put into the breeding pond, Bill told Qin Shiou: "The temperature requirements for the child's sea urchins are also high, but it doesn't matter in summer, just pay attention to the water quality."

Qin Shiou looked through the breeding manual and said, "You have to change the water twice a day to ensure that the water is more than one full amount every day, right? No problem, the oxygen content is also fine. My oxygen generators here are the most advanced."

Bill said: "Not only do we need to change the water, the childish sea urchin has strong feeding ability and excretion ability, so we have to pour the pond every 10 days to clean up the residual bait, feces and dead individuals."

Child sea urchins attach to the seedling board. They feed on benthic diatoms on the seedling board. These things are very edible because their growth involves a perverted process, so they need rich nutrition.

Under normal procedures, before attaching diatom seeds to the seedlings, diatom seeds should be placed first, and then during the breeding process, nutrient salt should be added to the breeding process to raise diatoms to grow nucleic sea urchins.

This is not necessary for Daqin Fishery. Raising diatoms is a time-consuming job. Qin Shiou directly collects seaweed and puts it on the seedling board. Their fishery produces high-quality seaweed and can achieve self-sufficiency.

Bill was more cautious and said, "I suggest that it is more appropriate to breed seaweed on the seedling board. You see, there are two layers of seedling board, and you can cultivate seaweed below."

Qin Shiou waved his hand and said, "I have a clear idea of ​​this, don't worry, there's no problem."
