Chapter 535

Plans are not as fast as changes.

Qin Shiou finally failed the next day.

At dinner, Qin Shiou thanked tsuka xiaotai's broadband and said he planned to go back tomorrow.

OTA Tezuka was surprised, showed a frightened expression and asked, "Qin sang, but I didn't treat well?"

"No, no, no, Mr. Tezuka, we are very satisfied with your hospitality, but there are common things at home, so I want to go back early." Qin Shiou explained that he didn't hit the smiling face. If people put their posture so low, he had to give people some face.

Hatsuka's face immediately changed and she laughed and said, "just be satisfied, Qin sang. Don't hurry back. Tomorrow I'll ask Mr. Nishimura to take you to Izu seven island. There is the best bluefin tuna farm in Japan. You are an expert in this field. Please give me more advice. "

Qin Shiou suddenly felt alive when he heard this. Hey, you take me to see your tuna farm? Didn't you put your daughter-in-law into the arms of a sex wolf? Then I really can't go.

When he hesitated, Tezuka xiaotai mistook him for not wanting to see it, so he immediately winked. Nishimura stood up and "pa" bowed: "Qin sang, please!"

Qin Shiou took advantage of the slope and promised to stay and go to the fishing ground for a few days. Then he will see the situation.

Izu seven island is just south of Tokyo, more than 1000 kilometers away. Nishimura Leng means to drive over, while Qin Shiou proposes to take a boat.

He doesn't care much about time. The key point is to take the sea route. Poseidon consciousness can carry out net fishing, and can take away things such as dolphins and amber fish together.

Nishimura Leng found a cruising boat, about 12.3 meters long, made of glass fiber reinforced plastic. The shape is streamlined. From the appearance, it is very beautiful. The name of the boat is also very beautiful. It is called the wind blowing snow sand.

The party first sailed from Tokyo to Nagasaki, boarded the ship at the Nagasaki port, and the cruise boat began to sail in a cloak.

Qin Shiou threw Poseidon consciousness into the water and suddenly found that underwater algae increased a lot compared with the previous two days.

This increase is explosive growth, and they are dense small algae. Small algae blend and grow and float quietly underwater. Poseidon consciousness swims along the offshore waters and sees these small algae.

Because it is almost impossible to connect with the Pacific Ocean outside, Tokyo Bay has become a dead water bay. Yes, there are waves in Tokyo Bay, but these waves are only the wind from the eastern Pacific Ocean, not the waves caused by the surging tide.

In this way, in addition to the surface, there is a dead silence underwater. What garbage and harmful substances can not be taken away by the waves in time. They still stay in place and accumulate more and more.

Seeing so many crazily breeding seaweeds, why doesn't Qin Shiou know what's going on?

Red tide! Red tide is breaking out again in Tokyo Bay!

Red tide is a historical name. It is not necessarily red. In fact, it is the general name of many red tides. Due to the different causes, types and quantities of red tide, the water body will show different colors, including red or brick red, green, yellow, brown, etc.

Even, red tides caused by organisms such as knee groove algae, naked dinoflagellate and pear dinoflagellate sometimes do not cause the sea water to show any special color. This kind of red tide is often difficult to prevent, and once it occurs, it will cause huge losses to the fishery.

The Tokyo Bay and the red tide are accompanied by each other, love and kill each other. It happened occasionally as early as the Fujiwara era and Kamakura era. With the beginning of the industrial revolution, the Tokyo Bay has become an industrial belt and a large-scale crowd gathering place.

In this way, a large number of human domestic sewage and industrial sewage are discharged into Tokyo Bay, which are nutrients of plankton. Without the push of waves, garbage cannot leave Tokyo Bay and enter the Pacific Ocean. Slowly, plankton, diatoms, cyanobacteria and brown algae begin to gather. When the number reaches the critical value, an explosion will be formed.

This cannot be changed by Qin Shiou. To avoid red tide, we can only form a complete and healthy marine biological chain.

If the Japanese didn't kill fish and dolphins in Tokyo Bay too much, and if they didn't pour sewage into Tokyo Bay so ferociously, there would be no red tide.

The red tide broke out so fast and so terrible. When the cruise yacht drove all the way south and was about to pass through the entrance of Tokyo Bay in Yokosuka, some red water blooms began to float on the water surface.

Nishimura is also a top graduate of Tokyo Fisheries University. Seeing these red seaweed appear, he sighed: "Oh, my God! Is there another red tide? Why is Tokyo Bay so miserable? "

As if to vent, Nishimura Leng said angrily, "it's all the fault of those factories. If you don't pour industrial sewage into the Bay, the Tokyo Bay can be as clear as it was 200 years ago. In this case, why should we go to Izu seven island to raise bluefin tuna? It's better to breed in Tokyo Bay! "

The water quality of Tokyo Bay usually looks clean. In fact, the pollution is also very serious. Bluefin tuna can't live in this environment.

Although tuna tastes good, they are not good food, because they usually feed on small fish species such as herring, mackerel and scaly fish. They accumulate a large amount of mercury in their bodies, which is very harmful to their health.

This is the result of tuna fleeing all over the four oceans. If they live in the Tokyo Bay, they are estimated to have died of heavy metal poisoning before they grow up.

The red tide has little to do with Qin Shiou. They sailed all the way to Xiatian port on Izu Peninsula, which is not far from Izu seven islands.

"Let's have something to eat here first, Qin sang. Please try Xiatian's Jiaji sashimi. It tastes great. It's world-famous." Nishimura Leng enthusiastically promoted and has come out of the impact of the red tide outbreak in Tokyo Bay.

Jiaji fish is snapper, which is divided into many kinds. Red snapper is abundant in the sea of Japan. It is large, delicious and has a festive name, so it is very popular in the whole Southeast Asia.

Qin Shiou is very interested in food. Under the leadership of Xicun Leng, they went to a small wine house next to the fishing port. The name of the wine house is three generations. Xicun Leng said that although the wine house is not famous, the boss has first-class skills in making Jiaji fish sashimi, which is the ancestral technology of the family.

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

Qin Shiou gave a thumbs up when he ate it. In fact, he praised Winnie. The fish fillet was not so delicious. It was cool and salty. It had the pungent taste of mustard juice, which covered up the freshness of the fish.

When looking at Daqin gull, he praised the fish fillet introduced by himself. Xicun Leng felt light on his face and smiled proudly.

While eating, Qin Shiou asked Nishimura Leng to introduce the cultivation of bluefin tuna on Izu seven islands.
