Hearing that the light echinococcus sea urchin had arrived, Butler rushed back in a dinghy, and after jumping on the dock, he began to shout: "Qin, Qin, where is my sea urchin?" ”

The corners of Qin Shiou's mouth twitched, and he took him onto the transport ship and asked him to check the round little thorn balls that were staying in the breeding box.

Butler pinched one with a clamp and held it to his eyes, his eyes were simple, as if a sculptor was admiring a fine piece of marble.

After looking at it for a while, Uncle Bearded exclaimed, "Oh God, this is the light echinococcus sea urchin?" Chinese and Japanese like to eat this thing? It looks so ugly and cute. ”

The corners of Qin Shiou's mouth twitched violently, Bill pulled him, and asked in a low voice, "This is the guy you said was very good at identifying sea urchins?" Really, uh, I can't tell from the outside. ”

Facing Qin Shiou's gloomy gaze, Butler laughed, he patted Qin Daguan's shoulder and said, "OK, OK, relax man, I'm just kidding, you must know that when I was fourteen years old, I followed my uncle to your North China Sea to fish for sea urchins." ”

Butler patiently observed the breeding box, then nodded and said: "No problem, it is indeed a light echinococcus sea urchin, the activity is great, well done man, it is rare to see such good goods now." ”

Hearing this, Bill had a smug look on his face and said, "It's not bad, I also got it through a little secret way." ”

Butler shook hands with Bill and said to Qin Shiou: "You have made a friend with energy, and the sea urchin market is too chaotic right now." A few days ago in Japan, I heard that Singaporean farms now like to use southern purple sea urchins to pass off as light echinococcus sea urchins, and some Japanese seafood merchants suffered. ”

Sea urchin is one of the traditional delicacies of East Asian countries. The edible part of this thing is sea urchin paste, which is nutritious, delicious and delicious, and has a good role of nourishing and strengthening the body.

Salted sea urchin, alcoholic sea urchin, chilled sea urchin, steamed sea urchin and sea urchin paste are popular among high-income groups.

With the increasing influence of East Asian countries in the world, and with the arrival of Chinese Americans, Japanese Americans, Koreans and other East Asian aborigines to the world, sea urchin paste is slowly becoming popular in the international market.

At present, the light echinococcus sea urchin paste produced in Northeast China is the world's top sea urchin product, and it is also very popular in Europe and the United States, and the demand exceeds the supply. At Prince William's wedding, which ended last year, there was echinocanthosis sea urchin cream at the wedding banquet.

The southern purple sea urchin mentioned by Butler is similar in appearance to the light echinococcus sea urchin, and its appearance is purple-black. So there are businessmen who often use them to pass off as light echinococcus sea urchins.

In fact, the southern purple sea urchin is also a treasure, but it is not as good as the light echinocobulus sea urchin, the former is cultivated in tropical waters, and the latter is the aboriginal of cold waters. Generally the same species. The value of cold water cultivation is higher than that of tropical waters.

These sea urchins sent by Bill are also sea urchin seedlings, the scientific name is juvenile sea urchins, they have particularly high requirements for water quality at this stage, of course, the water quality of Daqin Fishery is almost the first in North America, and 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 and don't care, if it is too troublesome to use natural stocking. Estimate how many sea urchins will float on the surface of the sea in a few days, of course. Dead.

Bill can cooperate with Qin Shiou so happily, that is, his ability is very strong, and he is reliable, he came over this time to prepare all the tools and techniques for sea urchin breeding, and Qin Shiou can apply them directly.

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

Among them, the seedling board is a non-toxic transparent PVC corrugated board, with a length of half a meter, a width of 40 centimeters, and a thickness of half a centimeter, with undulating ripples on the board, and a wave height of about 1.5 centimeters.

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

Bill brought a folding frame, and he asked the workers to open a demo and said, "You see, whether it's horizontal or vertical, in this kind of frame, the seedling picking board is not easy to come out." And this kind of frame area is large, the spacing of the seedling plates is large, and the plates are not easy to overlap, which is more suitable for sea urchin seedlings. ”

Check that everything is okay, then it is time to put it into breeding.

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

There were shrimp in the breeding pond before, Qin Shiou asked the fishermen to open the sluice gate and put the shrimp into the fishing ground, anyway, he had already input enough Poseidon energy to the shrimp, and the female shrimp who should have spawned have also spawned, and now it is no problem to enter the ocean.

After cleaning up the pond, Bill instructed the workers and fishermen to put the frames into it, and then set up the seedling boards on top of it, and finally put the young sea urchins on them.

A seedling board can breed about 40 juvenile sea urchins, they are now small, and they will have to divide the 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 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 looked through the breeding manual and said, "Change the water twice a day to ensure that the water is changed more than a full amount every day, right?" No problem, no problem with the oxygen level, the oxygen concentrators I have here are all state-of-the-art. ”

"It's not just about changing the water, it's also about feeding and excretion, so every 10 days or so, we have to pour the pool to clean up the bait, feces and dead individuals," Bill said. ”

Juvenile sea urchins attach themselves to the seedling plates, and they feed on the benthic diatoms on the seedling plates, which are very edible because their growth involves a metamorphosis process and therefore requires rich nutrients.

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

There is no need for this in the Daqin Fishery, raising diatoms is a time-consuming job, Qin Shiou directly collects seaweed and puts it on the seedling board, and their fishery is rich in high-quality seaweed, which can complete self-sufficiency.

Bill was more cautious and said, "I suggest that it is more appropriate to grow seaweed on the seedling board, as you can see, the seedling board has two layers, and the seaweed can be cultivated underneath." ”

Qin Shiou waved his hand and said, "I have a number of this, you can rest assured, it's no problem." ”

He asked the remaining bulls to drag a batch of diatoms with benthic nets, crush them and put them in the breeding pond: "Look, they don't have to wait, they can eat it directly, as for eating the rest?" That doesn't leave pollution and I can change the water every day. (To be continued......)
