Plans are not as fast as changes.

Qin Shiou didn't make it the next day.

During dinner, Qin Shiou expressed his gratitude to Kota Ozuka for his broadband, and then said that he planned to go back tomorrow.

Tezuka Kota was very surprised, and asked with a panicked expression, "Qin Sang, but I didn't entertain you well?" ”

"No, no, Mr. Tezuka, your hospitality has made us extremely satisfied, but there are still mundane things at home, so I want to go back early." Qin Shiou explained, don't stretch out your hand and don't hit the smiling person, if people put their posture so low, he also has to give people some face.

Tezuka's face immediately changed, and he laughed and said: "It's good that the two of you are satisfied, Qin Sang, don't rush back, tomorrow I will ask Nishimura-kun to take you to Izu Shichishima to have a look, where we have the best bluefin tuna farm in Japan." You're an expert in this area, so please give me some advice. ”

When Qin Shiou heard this, his heart suddenly became lively, hey, you take me to see your tuna farm? Isn't this stuffing the daughter-in-law into the arms of a pervert? Then I really can't go.

His hesitation, Tezuka Kota mistakenly thought that he didn't want to look, so he immediately winked, Nishimura stood up and bowed: "Qin Sang, please!" ”

Qin Shiou borrowed the slope to get off the donkey, and promised to stay and go to the fishing ground for a few days, and then see the situation before leaving.

Izu Shichishima is directly south of Tokyo, a distance of more than 1,000 kilometers, Nishimura means to drive there, and Qin Shiou proposes to take a boat there.

He doesn't care much about the time, the focus is on taking the sea route, and the sea god consciousness can launch a net-like fishing, and he can take away things like dolphins and amber fish when he encounters them.

Nishimura found a cruiser, about twelve or thirteen meters long, with a fiberglass texture. The shape is streamlined, and it is beautiful from the outside. The name of the ship is also very catchy, it is called the Wind Blowing Snow Sand.

The group sailed from Tokyo to Nagasaki. Embarking at the port of Nagasaki, the cruiser begins to sail through the waves.

After Qin Shiou threw the Seagod Consciousness into the water, he suddenly found that the algae under the water had increased a lot compared to the previous two days.

This increase is explosive, and it is all dense small algae, tiny seaweed grows together, floating quietly underwater, and the Poseidon consciousness swims along the offshore waters, and all you see is these small seaweeds.

Because it can barely be connected to the Pacific Ocean outside, Tokyo Bay has become a backwater bay. Yes, there are waves in Tokyo Bay, but these waves are only winds blowing from the Oriental Pacific Ocean, not waves caused by the surging tide.

In this way, except for the surface, the water is dead and silent, and any garbage and harmful substances cannot be carried away by the waves in time, and they remain in the same place, accumulating more and more.

Seeing so many little seaweeds that are wildly proliferating. How could Qin Shiou not know what was going on?

Red tide! Red tide is about to break out in Tokyo Bay again!

Red tide is a historical name, it is not necessarily red, in fact it is a collective name for many red tides. Depending on the cause, type, and number of red tides, the water will take on different colors. There are red colors or brick red colors, green, yellow, brown, etc.

In addition, red tides caused by organisms such as kneolulis, eugleniflagellates, and pear dinoflagellates sometimes do not cause the sea water to take on any special color, and such red tides are often difficult to prevent. If it happens, it will cause huge losses to the fishing industry.

The love and killing of Tokyo Bay and the red tide coincided with each other, and it happened occasionally as early as the Fujiwara and Kamakura periods. With the beginning of the Industrial Revolution, Tokyo Bay became an industrial belt and a place for large crowds.

This discharges a large amount of domestic and industrial sewage into Tokyo Bay. And this sewage is a nutrient for plankton. Without the impetus of the waves, the garbage cannot leave Tokyo Bay and enter the Pacific Ocean, and plankton and diatoms, cyanobacteria, and brown algae slowly begin to accumulate, and when the amount reaches a critical value, an explosion is formed.

This is something that Qin Shiou cannot change, and if he wants to avoid red tides, he can only form a complete and healthy chain of marine life.

If the Japanese hadn't been so aggressive in killing fish and dolphins in Tokyo Bay, and if they hadn't been so ferocious in pouring sewage into Tokyo Bay, red tides would not have occurred.

The red tide broke out so quickly and so terrifyingly, and as the cruiser headed south, about to cross the mouth of Tokyo Bay in the Yokosuka area, some red blooms had begun to float to the surface.

Nishimura Ryo is also a top student who graduated from Tokyo Fisheries University, and when he saw these red seaweeds appear, he sighed, "Oh my God! Is there another red tide? Why is Tokyo Bay so miserable? ”

As if to vent, Nishimura said angrily: "It's all the fault of those factories, if you don't dump industrial sewage into the bay, then Tokyo Bay can be as clear as it was two hundred years ago, so why should we go to Izu Nanachito to raise bluefin tuna?" Farming in Tokyo Bay is even better! ”

The water quality in Tokyo Bay looks clean, but in fact it is very polluted, and bluefin tuna cannot survive in this environment.

Although tuna tastes good, they are not a good food, because they usually live by preying on small fish species such as herring, mackerel, and capelin, and accumulate a large amount of mercury in their bodies, which is very dangerous to health.

This is the result of tuna scurrying across the four oceans, and if they had lived in Tokyo Bay, they would have died of heavy metal poisoning before they reached adulthood.

Chishio had little to do with Qin Shiou, and they sailed all the way to the port of Shimoda on the Izu Peninsula, which was not far from the Izu Shichishima Islands.

"Let's eat something here first, Qin Sang, please try Shimoda's kayoshi fish sashimi, it tastes great, it's world-famous." Nishimura Ryo was enthusiastically selling, and he had come out of the impact of the red tide that had erupted in Tokyo Bay.

There are many types of sea bream, but red sea bream, which is abundant in the Sea of Japan, is popular throughout Southeast Asia because of its large size, delicious taste, and festive name.

Qin Shiou was very interested in food, and under the leadership of Nishimura Ling, they went to a small tavern next to the fishing port, the name of the tavern is three generations, Nishimura Ling introduced that although this tavern is not famous, the boss's ability to make zuò Kaji fish sashimi is first-class, and it is an ancestral technique in the family.

After the boss sent sashimi of the same size and similar thickness, Winnie picked up a slice and dipped it in thick soy sauce on one side, and dipped it in mustard juice on the other side and fed it to Qin Shiou's mouth.

Qin Shiou gave a thumbs up when he ate, in fact, he praised Winnie, how could this fish fillet be so delicious, cool, salty, with the spicy taste of mustard juice, and even the umami of the fish was covered.

Looking at Daqin Shiou's praise for the fish fillet he introduced, Nishimura Ling felt that there was light on his face, so he smiled proudly.

While eating, Qin Shiou asked Nishimura Ling to introduce the situation of bluefin tuna farming on Izu Shichishima. (To be continued......) R1292
