Ye stopped in front of the aquarium in a store that seemed to have a wider variety of seafood.

Giant yellow croaker, treasure fish, moray eel, sea catfish...... A variety of live marine fish swim in the transparent aquarium.

In another aquarium, the white, fat geoduck squirmed slightly.

Live abalone, live sea cucumbers, and writhing sea intestines are packed in different transparent aquariums.

There are also a variety of live shellfish and shrimp......

Ye Zhenzhen carefully looked at each aquarium and compared the similarities and differences between the seafood in Lianhai City and the seafood in her hometown.

The owner of the restaurant saw a customer stop in front of the door and greeted him warmly, "Girl, what do you want to eat?" The seafood in my store is fresh and varied, and there are all the ...... you want to eat."

The shopkeeper was selling his seafood in Mandarin in the local dialect, and Ye Zhenzhen's eyes finally moved away from the aquarium, and she looked up and asked the shopkeeper, "Boss, what is the most local seafood in your store?"

The shopkeeper pointed to one of the aquariums with the fishing net in his hand, "This is the wave fish, a specialty of our Lianhai City, which grows in the shallow sea near the shore and in the brackish water at the mouth of the sea.

Ye Zhenzhen was just about to agree, but Nan Zhiqiao, who was standing on the side, suddenly grabbed Zhenzhen's hand, and asked the shopkeeper at the same time, "Have the wave fish in your store always been purchased from Nanwan Town?"

"Yes, I've been running this shop for six years, and I've always been picking up goods from Nanwan Town, which is close to the estuary, where the wave fish grow the best. ”

Nan Zhiqiao asked again: "In the past six months, has there been any change in the wave pushing fish that came in from Nanwan Town?"

Faced with the question of the strange handsome man in front of him, the shopkeeper was a little puzzled, not knowing what the other party wanted to inquire.

The shopkeeper looked Nan Zhiqiao and Ye Zhenzhen up and down, the man was handsome and extraordinary, and the woman was beautiful and moving, like a foreigner, not like she came to inquire about trade secrets, so he let down his guard and said: "The number of wave fish coming in from Nanwan Town recently is indeed not as large as before, so the price is much more expensive than before, but the quality is still the same as before, fresh and delicious." ”

The shopkeeper saw that the two of them were interested in the wave fish, and worked hard to sell the two of them: "We have a folk song in Lianhai City, which is about the wave fish, the first month of the year pushes the waves to boil fresh soup, the February waves are soft and lost, the waves are all over the wall in March, the waves are dried jackals in April, the six are born in May, and the sheep soup is rolled out in October." ”

Listening to the shopkeeper singing a folk song to attract customers, Ye Zhenzhen became interested and asked: "Boss, it's December, how should I eat the wave fish?"

"Fresh soup. ”

Ye Zhenzhen: "How much wave fish is suitable for boiling soup?"

"Two people can do it for a catty, and the soup boiled out in this way is thick and fresh. ”

"Okay, let's get a pound of wave-pushing fish. ”

The shopkeeper shouted loudly: "Okay, a pound of fish pushing waves!

The shopkeeper shouted as he prepared to use a fishing net to fish out of the aquarium.

Nan Zhiqiao suddenly stopped: "A pound of live wave pushing fish, you don't need to boil soup, we will pack it and take it away." ”

As soon as these words came out, the shopkeeper and Ye Zhenzhen were stunned, and the shopkeeper thought to himself, this customer is really strange, he comes to the seafood street to eat, how can he buy live fish and go back to make it himself? If you want to make it yourself, you will go to the seafood market.

Ye Zhenzhen also looked at Nan Zhiqiao questioningly.

Nan Zhiqiao glanced at Zhen Zhen, and Zhen Zhen knew that Nan Zhiqiao had his own intentions in doing this, so he followed Nan Zhiqiao's tone and said to the shopkeeper: "Well, live fish, pack and take it away." ”

The shopkeeper looked at the two people who bought the fish strangely, and didn't say anything, and called the fish good, "One pound of wave-pushing fish, twenty yuan." ”

Ye Zhenzhen took the fish, turned around and asked Nan Zhiqiao, "Senior Nan, what's next?"

Nan no Qiao asked the shopkeeper. "What seafood are you here that wasn't shipped from Southbay?"

The shopkeeper pointed casually, "More, these big yellow croakers, sea cucumbers, and ivory mussels are not transported from Nanwan Town, and these sea crabs are transported from the northern islands, they are big and fresh, and I will bring you two?"

Nan Zhiqiao took the bag containing the live wave fish from Zhen Zhen's hand and said, "Choose from these kinds of seafood that the boss said, is it big yellow croaker? or crab?"

"A big yellow croaker, two crabs, two catties of oysters, and a catty of mackerel dumplings, huh...... So much should be fine. ”

After Ye Zhenzhen finished ordering, she looked at Nan Zhiqiao and asked, "So many, is it okay?"

Nan Zhiqiao understood Zhen Zhen's appetite, and added another dish with a smile: "Add another pound of fried clams, and put more spicy." ”

Nan Zhiqiao knew that Zhen Zhen liked spicy food, and when she was in Paris, Zhen Zhen flew thousands of miles from her hometown to the Institut Pasteur in Paris with hot sauce.

While waiting for the food to be served, Ye Zhenzhen asked Nan Zhiqiao, "Senior Nan, what are you buying these live wave pushing fish back for? We can't cook by ourselves." ”

Nan Zhiqiao put the packed live wave pusher fish on the ground, and the wave pusher fish kept jumping, hitting the bag and making a sound of screaming, "These fish are transported from Nanwan Town, and Nanwan Town has recently had a case similar to Minamata disease. ”

South Bay Town, Minamata Disease, Wave Pushing Fish, Strange Disease, Methylmercury Poisoning......

Ye Zhenzhen connected everything and understood Nan Zhiqiao's intentions.

"Senior Nan, do you suspect that these wave-pushing fish contain methylmercury?"

"It's very likely that you will find out if you go back to the CDC for testing. ”

The small shop served quickly, braised large yellow croaker, steamed crab, spicy fried clams, oyster soup, and mackerel dumplings.

All the dishes were served on the table, Ye Zhenzhen took a few chopsticks, tasted them carefully, and smacked her lips, "There is no metallic taste." ”

Nan Zhiqiao smiled, "If you can taste the metallic taste, then this seafood is directly soaked in mercury, these seafood are not from Nanwan Town, and there are no strange patients in the urban area, so it should be safe." ”

Sandwiched a mackerel stuffed dumpling and put it in her mouth, Ye Zhenzhen chewed it, swallowed it, it tasted really good, and sighed: "Compared with the mackerel stuffed dumplings I wrapped, other seafood is also good, we humans are at the top of the food chain, there are many kinds of food." ”

Nan Zhiqiao sandwiched a piece of yellow croaker meat, picked out the thorns inside, put it in the bowl in front of Zhen Zhen, and said, "Being at the top of the food chain is not all advantages. ”

"Why? It's better to be at the top of the food chain than at the bottom, people eat fish, and don't like fish eat people. ”

Nan Zhiqiao gave an example, "If mercury leaks, mercury in the environment, especially trace amounts of mercury in water, can be concentrated to thousands to hundreds of thousands of times more through the gradual transfer and accumulation of phytoplankton-zooplankton-small fish-large fish in the water, and at the same time, inorganic mercury can be converted into highly toxic methylmercury." Methylmercury is stored in fish for a long time, and methylmercury poisoning occurs when contaminated fish are consumed by humans. ”
