Tuna, also known as tuna, is called tuna in Hong Kong, and its flesh is red because the tuna muscle contains a large amount of myoglobin. Delicious and fresh tuna has always been one of the favorite seafood dishes of Japanese and Taiwanese people, especially tuna sashimi.

In terms of tuna species, the quality of sashimi from high to low is bluefin tuna, masu tuna, bigeye tuna and yellowfin tuna. Bluefin tuna and massu tuna are produced in lower quantities and have a very high price, and the common tuna fillets are made from bigeye tuna and yellowfin tuna.

Tuna raw food is the best, cooked food is also fragrant and delicious, canned tuna soaked in oil made of albacore tuna and bonito, very delicious, not only loved by people in Southeast Asia, even people in Europe and the United States also like to use it to prepare sandwiches, deeply loved by the majority of consumers, the market is extremely broad, Japan, Western Europe and the United States are the three major markets for tuna products.

Since tuna must always swim fast to maintain its supply, and because it only moves in the deep sea, the meat is tender and delicious, and it is not polluted by the environment, making it a rare healthy delicacy for modern people.

The protein content is as high as 20%, but the fat content is very low, commonly known as the sea chicken, and the nutritional value is high. Most of the fatty acids in fish are unsaturated fatty acids, which contain a complete range of amino acids, and there are 8 kinds of amino acids required by the human body. It also contains vitamins, rich in iron, potassium, calcium, magnesium, iodine and other minerals and trace elements. EPA, also known as OMEGA3, is a nutrient unique to tuna. Tuna is rich in DHA, an unsaturated fatty acid that cannot be produced by humans themselves, and it is one of the nutrients necessary for the normal functioning of the brain.

DHA can enter the brain through the blood-brain barrier to increase and extend the synapses of brain nerve cells, thereby increasing brain volume, enhancing memory and understanding, and regular consumption is conducive to the regeneration of brain cells, improving memory and preventing Alzheimer's disease. In addition, DHA can soften the retina, improve retinal reflex function, strengthen vision, and prevent myopia, while EPA can promote the role of DHA in the body.

Chen Xing's Aristotle catches the most bonito and albacore tuna, but the most profitable are bluefin tuna and massu tuna. In the case of Chen Xingkai using Tianyan to find it, the proportion of these two most profitable large tuna has been greatly increased, so there is also a certain proportion of storage in the kitchen. When he was in the small town, Chen Xing didn't say that he had never eaten this kind of expensive sashimi, and he had never even heard of it.

I remember the first time the chef brought the cooked sashimi to the table, the Taiwanese were all dipped in the old soy sauce mixed with horseradish, feasting, even calling delicious, but the Fujian sailors and Chen Xing almost didn't vomit, eating raw meat, domestic people basically didn't think about it, even if it was sashimi, the poor people in the 90s had never eaten it. Not to mention the Russians, who basically don't eat raw food.

But after eating it a few times, Chen Xing became addicted to this delicious food, not only liked the super tender and smooth taste, the kind of stimulation that improved the deliciousness of the fish meat to the extreme through the flavor of horseradish, but also clearly felt that the body strongly absorbed a certain substance in the tuna meat through the Tianyan in the brain, and transmitted it to the Tianyan through the blood, and then filtered and purified by the Tianyan to transmit this substance to the brain, and the brain under the nourishment of this substance, the synapses of brain nerve cells continue to develop. Extended and changed, which further increased Chen Xing's brain capacity and enhanced his memory and comprehension.

Chen Xing made several internal comparisons and found that when eating ordinary food, Tianyan can also purify a certain substance from food through blood and convey it to the brain for moisturization, but the effect is minimal. The substance purified by tuna meat is dozens of times that of ordinary food, and at the same time, Chen Xing's spirit is comfortable and his thinking is clear.

As for why tuna meat has this effect, what kind of substance is absorbed and purified by Tianyan, and what effect it achieves in the moisturizing and development of the brain, it remains to be studied and discovered by Chen Xing. Suddenly, Chen Xing was full of curiosity about the changes in his body, and he was very eager to understand these changes, what direction would change, how much ability could it bring to himself, whether there were any side effects, and whether it would make others think that he was a monster.

Chen Xing decided not to talk to anyone about the changes in his body for the time being until these questions were clear.

At 18:00 on the evening of October 1, 1995, the Chinese National Day. The Aristotle returned to the sixth day of its last departure.

The fishing chief is very happy today, coming back for 6 days, under the discovery of Chen Xing, he found three fish schools and laid three nets, each net is more than 80 tons, about 20% of the yellowfin tuna and bigeye tuna, 5% of the bluefin tuna and Masu tuna, this time not only the loss is made up, but also a lot of profits, so he sees everyone smiling.

This afternoon, Chen Xing also found a driftwood, and observed with the eye of the sky, the surrounding fish schools were good, even if he used sonar, he could see the shadows of the large clusters of fish gathered together, and the fishing chief decided to go down this driftwood tomorrow.

Everyone has plenty of time, Ivan and the imp go down in a speedboat to tie a flash and diving lamp to this driftwood, and the rest depends on the effect of tomorrow's netting.

In order not to affect the gathering of fish, Aristotle drove to a distance of 5 nautical miles from the driftwood, about 10,000 meters, which should be the best waiting position given by the old sailors.

Since the fish caught well recently, the fisherman was happy, and after dinner, at 7 o'clock, everyone was allowed to turn on the close-up searchlight on the side of the boat with their backs to the target driftwood, so that everyone could relax by fishing for squid. This event is the first time Chen Xing has participated in this event, and it is also a new thing to see how the squid he likes to eat is caught.

The searchlight shines on the side of the ship, and the sea water can be seen at a depth of about 2-3 meters. Squid is a creature to the light, under the light, you can clearly see groups of dark red squid in the sea more than a foot long shuttling up and down, with the white light, the dark night, the light under the blue water, very beautiful. Moreover, Chen Xing also found that there is a small fish in the sea, which is also phototropic, about half an inch long, and often jumps several times in a row like a grasshopper on the sea surface, flying out of the light like fireflies, which is very cute.

Captain Pan took out 2 sets of homemade squid fishing hooks and issued them to Chen Xing. It is to fix six large fish hooks on a small stick more than 30 centimeters long, which looks like a circle of circular fountains when it falls. Then the two sets of fishing hooks are tied to the fishing line, and there is no fishing rod, so directly drag the fishing line with one hand, and throw the fishing hook to the light in the sea with the other hand, and the hand holding the fishing line keeps shaking, causing the squid to swim towards the hook and string it around the hook.

I saw Captain Pan's hand shake, and a squid was hung on the hook, rising out of the sea, and he was still on the deck. Everyone shouted excitedly, it was Chen Xing and the sailors of Fujian Province who came to see the squid fishing, they were all seeing this scene for the first time, and those Russian sailors did not come at all.

The squid on the deck was illuminated by the light, and the dark red body immediately turned white, and the "ink" in the stomach slowly flowed out as the body expanded and contracted. Captain Pan cut the squid, took out the internal organs, cut half of the white squid flesh and tied it to the hook's small stick as bait. He said to Chen Xing: "When you look at the sea, if the squid's body is red, it means that it is still hungry, and if its body is white, it means that it is full, so you should focus on the red squid, and it's fine." ”

According to Captain Pan's guidance, Chen Xing also caught 7 or 8 squid. By 8 o'clock, a total of 18 fish were caught, which was enough for everyone to add dishes in the past two days.
