readx; Hearing that the echinococcus sea urchin was delivered, Butler rushed back in a small boat excitedly. After jumping onto the pier, he started to yell, "Qin, Qin, where is my sea urchin?"

Qin Shiou's mouth twitched, and he took him aboard the transport ship, and asked him to check out these round little spiny balls in the breeding box.

Butler pinched one with a clip and held it in front of his eyes, with innocent eyes, like a sculptor admiring a piece of fine marble.

After looking at it for a while, the bearded uncle exclaimed, "Oh, God, is this the echidna urchin? 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, "This is the guy you said is very good at identifying sea urchins? Really, uh, how should I put it, I can't tell from the outside."

Facing Qin Shiou's gloomy gaze, Butler burst out laughing. He patted the official Qin on the shoulder and said, "ok, ok, relax buddy, I'm just joking, you know I followed when I was fourteen Uncle went to your North China Sea to catch sea urchins."

Butler patiently finished observing the breeding tank, then nodded and said, "No problem, it is indeed an echinococcus photicus sea urchin. The activity is very good, and you have done a good job, buddy. It is rare to see such a good product now."

After hearing this, Bill showed a smug look on his face, and said, "Not bad, I also got it through a little secret way."

Butler and Bill shook hands, and said to Qin Shiou: "You have made a friend with energy. The sea urchin market is too chaotic now. I was in Japan a few days ago. I heard that Singapore farms now like to use southern purple sea urchins to pretend to be light thorns. Ball sea urchins, some Japanese seafood merchants have suffered.

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, which is nutritious, delicious, and has a good effect of nourishing and strengthening the body.

Foods such as salted sea urchins, alcoholic sea urchins, chilled sea urchins, steamed sea urchins and sea urchin sauces processed with sea urchin paste as raw materials are very popular among the high-income class.

With the increasing influence of East Asian countries in the world, and with the arrival of East Asian aborigines such as Chinese, Japanese, and Koreans to all parts of the world, sea urchin ointment is slowly becoming popular in the international market.

Now the Echinococcus glabra sea urchin ointment produced in Northeast China is the top sea urchin product in the world. It is also very popular in Europe and the United States, and the supply is in short supply. At the wedding of Prince William, which ended last year, there was Echinococcus sea urchin ointment at the wedding banquet.

Butler said the southern purple sea urchin looks similar to the echinococcus photica. The appearance is purple and black, so some merchants often use them to pretend to be echinococcus urchins.

In fact, the southern purple sea urchin is also a treasure.

It's just not as good as the Echinococcus glabra sea urchin, the former is cultivated in tropical waters, and the latter is an aborigine in cold waters. Generally, the value of the same species cultivated in cold waters is higher than that in tropical waters.

The sea urchins that Bill sent are also young sea urchins, whose scientific name is juvenile sea urchins. They have particularly high water quality requirements at this stage. Of course, the water quality of the Daqin Fishing Ground is almost the best in North America, so it must meet the requirements.

Sea urchin farming 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. There are as many sea urchins as there are sea urchins floating on the surface of the sea. Of course, dead.

Bill and Qin Shiou can cooperate so happily because he is very capable and reliable in doing things. He has prepared all the tools and techniques for sea urchin breeding this time, and Qin Shiou can just apply them directly.

The tools needed in breeding are the seedling board and the frame. The seedling board is used to collect the juvenile sea urchins attached to metamorphosis, and can also be used as the attachment substrate for the cultivation of juvenile sea urchins and provide diatom bait for the seedlings attached to the metamorphosis. The frame is mainly It is used to assemble the seedling picking board to make it easier to operate and manage.

in. The seedling picking board is a non-toxic transparent polyvinyl chloride corrugated 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, and the wave height is about 1.5 centimeters.

There are two types of frames for assembling seedling picking boards: basket type and folding type. Each frame can assemble 20 seedling boards.

What Bill brought was a folding frame, and he asked the workers to open one to demonstrate, saying: "You see, no matter whether it is placed horizontally or vertically, in this frame, the seedling picking board is not easy to fall out. And this frame area Large. The spacing between the seedling boards is large, and the boards are not easy to overlap, which is more suitable for raising sea urchin seedlings."

Check everything is ok, then it's time to put into breeding reads;.

Ordinary fish farms have dug aquaculture ponds, but Daqin Fish Farm has ready-made ones, which are engineered aquaculture ponds, which are more advanced and larger in size.

There were prawns in the breeding pond before. Qin Shiou asked the fishermen to open the sluice and put the prawns into the fishery. Anyway, he had already input enough Poseidon energy into the prawns. The female shrimps that should spawn have also laid eggs. Now it is no problem to enter the ocean. .

After tidying up the breeding pool, Bill directed the workers and fishermen to put the frames into it one by one, then set up the seedling boards on them, and finally put the juvenile sea urchins on.

One seedling board can raise about forty juvenile sea urchins. They are small now, and they will have to be divided when they grow up, so more can be raised.

After 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, you just need to pay attention to the water quality."

Qin Shiou flipped through the breeding manual and said, "The water needs to be changed twice a day. Make sure that the daily water change is more than one full amount, right? No problem, and the oxygen content is also no problem. The oxygen generators here are all the most advanced."

Bill said: "Not only do we need to change the water, juvenile sea urchins have a strong ability to eat and excrete, so we need to empty the tank every 10 days or so to clean up residual bait, feces and dead individuals."

Juvenile sea urchins are attached to the seedling board, and they feed on the benthic diatoms on the seedling board. These things 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 should be placed first, and then during the breeding process, nutrient salts are added to the juvenile sea urchins by growing diatoms.

The Daqin Fishery doesn’t need to do this. Diatom cultivation is a time-consuming job. Qin Shiou directly collects seaweed and puts it on the seedling 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 grow seaweed on the seedling board. As you can see, the seedling board has two layers, and seaweed can be grown underneath."

Qin Shiou waved his hand and said, "I know this, don't worry, it's fine."

He asked the left-behind bull to take a group of diatoms with a benthic net, crush them and throw them into the breeding pond: "Look, they don't have to wait, they can eat them directly. As for the leftovers? That won't stay. If there is no pollution, I can change the water every day." (To be continued.)
