Of course, no matter the price, it still costs money to buy these shellfish, but there are also ways to save money, that is, go to the seaside and deduct them yourself, such as the Danish oysters fried in the previous paragraph. But don't most people have the money and time to go to Europe to eat oysters? Relatively speaking, there is another way to get it, and that is to go out by boat. ......
Most of the photos of the ships you see, especially those in the dock, are new ships, smooth and clean. But when the ship sails in the water for a period of time, there will always be various aquatic organisms attached. On the one hand, these creatures will increase the weight of the hull (each one is small, adding up to more), because the uneven surface will increase the resistance, and will also block the water injection ports of some equipment at the bottom of the ship, which will affect the normal operation of the ship. Therefore, every once in a while, the bottom of the ship must
The bottoms of the new boats are sparkling.
When the ship returns to the dock again, the image will generally be miserable, so scraping the bottom of the ship has become an annual event for the ship. (The following contents are not recommended for parents who are eating seafood. )
Pay attention to the four "blocks" on the side of the propeller. That's a sacrificial anode, not an accessory.
A hull with many barnacles attached.
Of course, these accessories are actually quite common seafood. . . . Today, Bian Xiao will introduce several main attachments, among which the most attached ones, such as the one in the above picture, are called barnacles. There are two kinds of barnacles commonly attached, one is the conical barnacle commonly seen in the above picture, and the other is the goose-neck barnacle, which is also called bergamot or cantaloupe in China.

Of course barnacles are not delicious when they are young, but they still have some meat when they grow up. At the same time, barnacles on some ships may grow very big and naturally have meat after being immersed in seawater for a long time.
Barnacles can also grow very big.
According to the tradition of China people, as long as something is organic, especially if it is classified as "fleshy", three classic philosophical questions can be asked: "Can it be eaten?" "Is it delicious?" "How does it eat?" Surprised to hear this "three questions between heaven and man", I seem to hear the roar of countless "ghosts" in Guijie garbage dump "Can I still save it?"
Classic creatures were wiped out by China people's mouths.
Barnacle soup, which looks ordinary, is said to taste good.
Barnacles are no exception. If traditional barnacles eat less, then gooseneck barnacles eat more, and it's not just China's "bergamot". Europeans prefer gooseneck barnacles.
The broken "bergamot".
Although the "tail" of gooseneck barnacles is relatively long, its edible part is mainly in the hard shell of the head. This product is not cheap in the European market.
Goose-necked barnacles on the European market
In China, it seems that for bergamot, one of the main methods is frying, such as frying shellfish, or cooking scallops and dipping them in vinegar, as everyone did when they were young.
Boiled barnacles
Europeans have more ways to make gooseneck barnacles, although it doesn't seem to be to China's taste. . . . Stewed aquatic products with tomatoes always feel like dark cooking. ......
Oysters are second only to barnacles in the hull. For a long time, oysters are not only Chinese and western cuisines, but also a headache for ships.
Oysters on ships are not uncommon.
How to eat oysters? Needless to say this. Stir-fried, boiled, stewed, raw and cooked. . . By the way, which big boss told me why cooking soft-fried oysters at home is always an understatement, and how did the restaurant do it?
Oyster is a good thing, and the west thinks it has aphrodisiac effect.
After Bian Xiao, it was not until westerners used oysters to refer to female organs that I suddenly became confused about the primary school text My Uncle Yule. . . . . Some metaphors are really. . . . Well, think about the pictures described in the article. . . I drool when I'm hungry in class. . . .
Garlic oysters that must be ordered for barbecue
Competing with oysters for the second place, the total amount is similar to Haihong. This kind of shell is very sharp, in fact, there are ordinary shellfish attached to it.
The dense sea rainbow on the hull.
In fact, many times there are more sea rainbow attached to the hull than oysters, but after all, this product doesn't seem to be very delicious. . . . . Moreover, as a cheap seafood, this product seems to be better as an ornament than direct consumption. This product is also called mussels, sea eggs and so on.
The water content may be small, and the taste is not as fresh as other shellfish.
Of course, other shellfish sometimes attach to the hull on a small scale, but the total number is very small, such as scallop shellfish in our general sense (but much less than barnacles and various oysters).
The bottom drain pipe may have a variety of accessories.
Of course, this is not just a scallop in our general sense, but for most foodies like Bian Xiao, well, as long as it is not poisonous and delicious, I don't care what it is. . . .
Barnacles are common on scallops.
Of course, attachments are not limited to shellfish, but also many plants and aquatic plants. The following is the state diagram of the stones near the plagiarism line after low tide:
Please tell me how many kinds of seafood you see, ah no, seafood, ah no, aquatic life. The most conspicuous are the ribbon and sea cabbage. . . . . This is a stone that embodies biodiversity. Can someone explain what's orange below? Of course, the proportion of plants attached to the hull will be less, but many ships will still attach various aquatic plants. But it is more common in inland river vessels.
A boat full of aquatic plants
Sir, don't go away objectively. Would you like a plate of fresh seaweed/cabbage mixed with kelp to appetize?
Of course, back to the ship, these aquatic products are not good for the ship. One is to increase the weight of the hull, the other is to increase the navigation resistance of the ship, and the third is that the accessories are corrosive and will affect the hull. Fourth, after all, the bottom of the boat is not a smooth plate. Some devices, such as the water inlet, are used for engine cooling and other purposes, such as fin stabilizer, such as bow lateral thrust. The more these structures, the easier it is to attach aquatic organisms. These organisms either block the water inlet, affecting the efficiency of water intake, or block some moving parts, resulting in slow operation. Therefore, these accessories should be cleaned regularly.
After peeling off the accessories, the wood was seriously corroded.

Because large ships do not often have the opportunity to enter the dock for dredging, and most of them are all kinds of commercial passenger and cargo ships in the world, stopping the ship means a decrease in income. Therefore, in addition to entering the dock to clean the attachments on the hull during maintenance, many modern companies have started underwater dredging business. When the ship stops at the port to load and unload people and goods, divers go into the water to clean up some places where aquatic organisms are easy to attach to the ship. Of course, it is impossible to clean up a large area, but it can also effectively restore key parts.
Divers clean the hull.
The diver is holding a big electric "steel brush". Metal brush is used in the early stage, and high-strength material brush is used in the later stage to polish and clean the attachments. In the dry dock, the cleaner washes the attachments with a high-pressure water gun.
Appearance of cleaning brush
Of course, it is dangerous for people to work underwater, so now there are some new cleaning machines that can be hung on the hull and run by themselves to clean the attachments on the hull.
If anyone is interested in collecting enough shellfish from the ship, even if there are shrimps lying on the hull that has not been cleaned for a long time, you can gather a large pot of seafood chowder, such as the following:
I advise you not to eat it. After all, the underwater coating of modern ships is toxic, which is used to reduce the attachment of aquatic organisms. If it weren't for these paints, you might have harvested several cars of calcium carbonate a few months after sailing. .....
