    Hearing that the Echinococcus glabra sea urchin had been delivered, Butler happily drove back in the boat. After jumping on the dock, he started shouting: "Qin, Qin, where is my sea urchin?"

    Qin Shiou¡¯s mouth twitched, and he took him onto the transport ship and asked him to check out these round little thorny balls in the breeding box.

    Butler picked one up with a clip and held it up to his eyes, his gaze pure and simple, like a sculptor admiring a fine piece of marble.

    After looking at it for a while, the bearded uncle exclaimed: "Oh, God, this is the Echinococcus glabra sea urchin? Do the Chinese and Japanese like to eat this thing? It looks so ugly and cute."

    The corner of Qin Shiou's mouth twitched violently. Bill pulled him and asked in a low voice: "Is this the guy you mentioned who is very good at identifying sea urchins? It's really, uh, how should I put it, you can't tell from the appearance."

    Facing Qin Shiou's gloomy gaze, Butler burst out laughing. He patted Qin Daguan on the shoulder and said: "Okay, okay, relax, buddy, I was just joking. You know, I followed him when I was fourteen years old.  Uncle went to your North China Sea to catch sea urchins."

    Butler patiently observed the breeding box, then nodded and said: "No problem, it is indeed Echinococcus glabra. The activity is very good. Well done, man. It is rare to see such good products now."

    After hearing this, Bill showed a proud look on his face and said: "Not bad, I also got it through some secret ways."

    Butler shook hands with Bill and said to Qin Shiou: "You have made a powerful friend. The sea urchin market is too chaotic now. In Japan a few days ago, I heard that Singaporean farms now like to use southern purple sea urchins to pass themselves off as Acanthus glabra.  Some Japanese seafood merchants have suffered losses due to sea urchin."

    Sea urchin is one of the traditional delicacies of East Asian countries. It is one of the eight treasures of the ocean. The edible part of this thing is sea urchin paste. It is rich in nutrients, delicious, and has good nourishing and physical strengthening effects.

    Foods such as salted sea urchin, alcoholic sea urchin, chilled sea urchin, steamed sea urchin and sea urchin paste made from sea urchin paste are very popular among high-income people.

    As the influence of East Asian countries in the world increases, and as Chinese, Japanese, Korean and other East Asian aborigines come to all parts of the world, sea urchin ointment is slowly becoming popular in the international market.

    Nowadays, the Echinococcus glabra sea urchin paste 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 exceeds demand. During Prince William's wedding that ended last year, Echinococcus glabra sea urchin paste was served at the wedding banquet.

    The southern purple sea urchins Butler mentioned are similar in appearance to the Echinococcus glabra sea urchins. They are both purple-black in appearance, so businessmen often use them to pass off as Echinococcus glabra sea urchins.

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

    The sea urchins Bill sent are also sea urchin seedlings, and their scientific name is juvenile sea urchins. They have particularly high requirements for water quality at this stage. Of course, the water quality of Daqin Fishing Ground is almost the best in North America, so it will definitely meet the requirements.

    Sea urchin farming is more troublesome than fish, shrimp and crab farming. You need to put them on the seed collection board first, rather than throwing them directly into the sea. If it is too easy to use the natural stocking method, it is estimated that how many will be thrown away in a few days.  Sea urchins There are so many sea urchins floating on the sea surface, of course, they are dead.

    The reason why Bill can work so happily with Qin Shiou is that he is very capable and reliable. He came here this time and prepared all the tools and techniques for sea urchin farming. Qin Shiou can just apply them directly.

    The tools needed in culture are seedling boards and frames. The seedling boards are used to collect juvenile sea urchins that have attached to the metamorphosis. They can also be used as an attachment substrate for cultivating juvenile sea urchins and provide diatom feed for the post-metamorphosis seedlings. The frame is mainly  Used to assemble seedling harvesting boards to make them easier to operate and manage.

    ??Among them, the seedling collection board is a non-toxic transparent corrugated polyvinyl chloride board with a length of half a meter, a width of 40 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 seedling boards: basket type and folding type. Each frame can assemble 20 seedling boards.

    Bill brought a folding frame. He asked the workers to open one for demonstration and said, "Look, no matter whether it is placed horizontally or vertically, in this kind of frame, the seedling board is not easy to come out. And the area of ??this kind of frame  If the size is larger, the spacing between the seedling boards will be larger, and the boards will not easily overlap, which is more suitable for sea urchin seedlings."

    After checking that everything is OK, it¡¯s time to start breeding.

    Ordinary fisheries dig a breeding pond, but Daqin Fishing Farm has a ready-made one, which is an engineered breeding pond., more advanced and larger in area.

    There used to be prawns in the breeding pond. Qin Shiou asked the fishermen to open the sluice and put the prawns into the fishery. Anyway, he had injected enough Poseidon energy into the prawns. All the female prawns that were supposed to lay eggs have also spawned. Now they have no problem entering the ocean.  .

    After cleaning up the breeding pond, Bill directed the workers and fishermen to put the frames into it one by one, then set up the seedling collecting board on top, and finally put the juvenile sea urchins on it.

    A seedling board can breed about forty juvenile sea urchins. They are small now, and they will need to be divided into seedlings when they grow up, so more can be cultured.

    When the sea urchins were put into the breeding pond, Bill told Qin Shiou: "Juvenile sea urchins also have high temperature requirements, but it doesn't matter in summer. Just pay attention to the water quality."

    Qin Shiou looked through the breeding manual and said: "You need to change the water twice a day, and ensure that the daily water change is more than a full amount, right? No problem, the oxygen content is no problem, the oxygen concentrators here are the most advanced."

    Bill said: "Not only do you need to change the water, but juvenile sea urchins have strong feeding and excretion abilities, so the pond needs to be drained every 10 days or so to clean up residual bait, feces and dead individuals."

    The juvenile sea urchins are attached to the seedling board, and they feed on the benthic diatoms on the seedling board. These are very edible, because their growth involves a metamorphosis process, so they need rich nutrition.

    Under the normal process, before attaching juvenile sea urchins to the seedling board, diatom seeds must be placed first, and then during the breeding process, nutrients are added to them to raise juvenile sea urchins by growing diatoms.

    Daqin Fishing Ground does not need to do this. Raising diatoms is a time-consuming job. Qin Shiou directly collects seaweed and puts it on the seedling harvesting board. Their fishery is rich in high-quality seaweed and can be self-sufficient.

    Bill was more cautious and said: "I suggest that it is more suitable to cultivate seaweed on the seedling board. As you can see, the seedling board has two layers, and seaweed can be cultivated below."

    Qin Shiou waved his hand and said, "I know this, don't worry, it'll be no problem."

    He asked the left-behind bull to lead people to use benthic nets to haul up a batch of diatoms, crush them and throw them into the breeding pond: "Look, they don't have to wait, they can eat them directly. As for eating the rest? That won't be left behind."  To reduce pollution, I can change the water every day.¡± (Remember the website address: www.hlnovel.com
