Nan no Qiao picked up a long pebble and a kelp root on the beach, leaned over the dead fish that had just been patted ashore, and used the corner of the pebble to pick up the gills of the dead fish.

The red slime covered the entire gills, and the fish was mechanically blocked by the plankton in the red tide, and the fish suffocated to death!

Just as Nan Zhiqiao and Ye Zhenzhen were looking down to study the dead fish that were slapped ashore by the red tide waves, behind the two, from far and near, a motor sound sounded.

The beach is silent and empty in the early morning, except for the sound of the waves, and the sound of the motor suddenly intruding, which is very harsh.

A submarine tractor slowly drove out of the fishing village behind the reef.

The red tractor head, thick tires, and a small fishing boat in the frame behind it.

The sandy beach here juts gently into the sea from the small fishing village on the shore, and fishing boats cannot dock into the sea, so they rely on tractors to pick them up and drop them off.

The tractor carrying the small fishing boat into the sea went to the sea, and when it passed by Nan Zhiqiao and Ye Zhenzhen, the driver of the car deliberately stopped the car and shouted at the two: "Come to the sea so early?"

The driver, an uncle in his fifties, with sun-tanned skin, grinned and bared two rows of white teeth, smiling at the two men.

Ye Zhenzhen was still holding a seashell with an open mouth in her hand, Nan Zhiqiao was holding a pebble in her hand, and a kelp root, and the two of them did look like a little couple who came to the sea early in the morning.

Ye Zhenzhen nodded at the driver and asked, "Master, are you going to go to the sea to fish?"

"Yes, the sea water has not been clean recently, and you have to go to the deep sea to catch fish, and don't pick up dead fish and shells on the beach, it may be poisonous. ”

"The water is not clean? ”

The driver was stunned for a moment, but quickly reacted, "Oh, it's those red seawaters, a few days ago, the water in the open sea was red, but I didn't expect it to spread to the beach this morning." ”

Nan Zhiqiao frowned slightly, and asked, "How far is the farthest red sea area from the shore?"

The driver's uncle thought for a while, "It's about ten nautical miles, and each reddened place is different in size and shape, some are as big as a round football field, and some are long strips along the ocean current. ”

The driver's uncle said a few words, and someone on the fishing boat dragged behind the tractor in the sea urged, "Let's go, no matter how late it is, the fish will die more." ”

"Okay, let's go......"

When the tractor carries the small fishing boat into the sea, and when it reaches a certain depth, the small fishing boat floats on its own, turns on the motor on the fishing boat, and the small fishing boat breaks away from the submarine tractor and quickly disappears on the sea level.

Nan Zhiqiao and Ye Zhenzhen rushed to the beach overnight last night to watch the sunrise over the sea, and as a result, not only did they have a beautiful sunrise, but they also saw a rare red tide eruption.

It's just that the outbreak of the red tide is not a good phenomenon, Ye Zhenzhen was still moved by the beautiful sunrise on the sea just now, but when she saw the red tide on the seaside, her heart was a little blocked.

Nan Zhiqiao patted Ye Zhenzhen's shoulder and pointed to the location of the car again, "Zhenzhen, you wait here, I'll go to the carriage to get something." ”

"Take what?"

"Sampling box!"

Nan Zhiqiao said that he had run away.

Ye Zhenzhen stood on the seashore, looking at the back of Nan Zhiqiao trotting away, and reacted, Senior Nan is going to sample the seawater.

Only, how did he know that there was a red tide outbreak here? Or did he always have a sampling box in his car in case he needed it?

According to the character of Senior Nan, the latter is more likely.

Soon, Nan Zhiqiao trotted back with the sampling box.

Handing the sampling box to Ye Zhenzhen to carry, Nan Zhiqiao opened the sampling box, took out two wide-mouth sampling bottles from it, filled them with red tide seawater, and put a few dead fish and dead shells on the shore into the sampling bag.

Everything was put into the sampling box, and when the lid was closed, Nan Zhiqiao carried the sampling box back into his hands.

When I returned to the central laboratory of the CDC in China from the beach, it was already ten o'clock in the morning.

Because the dissertation defense had just ended, and it was a weekend, it was rare to see no students in the laboratory.

In the huge laboratory, only the sound of machines running.

The red tide sample taken from the beach was put in the laboratory, and Nan Zhiqiao immediately examined it under a microscope.

Under the microscope, a swarm of flagellatte-covered unicellular algae is moving irregularly.

After adjusting the field of view of the microscope, Nan Zhiqiao pulled Ye Zhenzhen over, "Zhenzhen, look, what is this?"

Approaching the binoculars, in the round and slightly bright field of view, a single-celled biflagellated round seaweed is dividing its cells, looking like two small cells glued together.

"It's a diflagellated!" Ye Zhenzhen immediately said her judgment.

"Yes, it's dinoflagellates, and it's the culprit that caused this red tide. ”

Glancing at the dinoflagellates under the microscope again, Ye Zhenzhen asked worriedly: "Senior Nan, I know that it is the red tide caused by the dinoflagellates, so how to deal with it?"

"There are many ways to control the red tide, physical, chemical, and biological methods, but this is not a problem for us to worry about, for this red tide outbreak, there will be the marine department itself to deal with it, I sampled back, just curious about these red ghosts. ”

The red ghost?curious?!hehe, it's really the style of Nandajin.

Nan Zhiqiao turned off the microscope and pulled Ye Zhenzhen out of the central compound.

"Senior Nan, where are you going to take me?" Ye Zhenzhen sat in the co-pilot seat and turned her head to look at Nan Zhiqiao.

"Date!"

Nan Zhiqiao's serious appearance made Ye Zhenzhen think that the two of them were going to deal with some work, and now a sentence of "date" suddenly appeared, and Ye Zhenzhen was stunned for a while.

I just watched the sunrise over the sea in the morning, and now I have to go on a date, and I feel pretty good, but I don't know what the next date will be.

Ye Zhenzhen looked at Nan Zhiqiao expectantly.

While driving, Nan Zhiqiao glanced sideways at the woman beside him, and met Ye Zhenzhen's expectant eyes, Nan Zhiqiao asked with a smile: "Zhenzhen, where do you want to go?"

"Anywhere, as long as I'm with you. ”

"How about watching a movie?"

"Good. ”

Ye Zhenzhen agreed, and suddenly remembered that she had agreed with the children in the Child Welfare Center that she would send them handmade biscuits this weekend, "Senior Nan, there is one more thing, I have to go to the Child Welfare Center today, the handmade biscuits were made yesterday, just send them today." ”

"Okay, I'll go home with you to get the biscuits, and then we'll go to the movies. ”

——

Downstairs in the Xincheng apartment, Nan Zhiqiao parked the car in the shade of a tree, and Ye Zhenzhen carried her small bag on her back, ready to go upstairs to get cookies.

As soon as he reached the top of the stairs, a figure blocked the way.

"Gao Xiaowei?!"

Ye Zhenzhen's previous blind date Gao Xiaowei blocked the staircase of the Xincheng apartment at some point.

Seeing Ye Zhenzhen coming back, Gao Xiaowei greeted her very warmly, "Sister Zhenzhen, I've been waiting for you for a long time." ”
