Emperor red snapper sashimi
Wonder of the origin of the name
I had the opportunity to deal with interesting fish this year. Its name is Emperor red snapper, the author is the first cooked fish, which is usually a rare fish that can not be eaten.
The following image is Emperor red snapper. It was not certain even if we looked at what the origin of the great name came from, the weight of the fish handled by the author exceeded about 8 kg, and it was about 1 m in size. That splendid form was a wonderful thing that could not beat the name of a thousand years.
As the English name is Emperor red snapper, as the name of the emperor is English, it seems that such a big figure seems to be very good also for foreigners, and the name Sennen Dai is "worth a thousand years" I want to speculate that it means.
When juvenile fish becomes adult fish, its appearance is a big transformation
The habitat is a warm sea from South Japan to Nansei Islands and tropical waters, living in shallow sea coral reefs and reefs, and its larval fish live near the coast.
Emperor red snapper is called sunbanner in Okinawa and sunballadei in Amami Oshima. The sunbanner is a triangular hat knitted with the leaves of Kuba (palm family plant), which sees fishermen of fishermen and people of Okinawa being covered,
Emperor red snapper also lies in the shape of larval fish From the point of view, the shapes of the triangles are certainly similar.
Emperor red snapper's larval fish is the lower left image. I think larval fish is in a form that can not be imagined very much from the majestic red splendid figure of a grown adult fish.
Larval fish with a high height has a large red-black horizontal stripe prominent, it is shaped like a "small" or "river" of kanji, and it is a clear horizontal stripe pattern, but when growing further bigger, As the clarity of red-black horizontal stripes disappears, the stripes gradually become blurred.
Such a change in striped pattern can be seen also in other fish, for example in the case of parrot fish introduced in FISH FOOD TIIMES No. 79 July 2010 issue, as in the image below The horizontal stripes of larval fish also disappear when becoming adult fish.
Emperor red snapper belongs to the Perciformes eye Percoidei subspiny Lutjanidae family Lutjanus genus and parrot fish is Perciformes eye Percoidei subterraneil Oplegnathidae family Oplegnathus genus so even if the name of Japanese sea bream is the same, basically another fish species , Why does it change the disappearance of similar horizontal stripes?
What stripe pattern means
In the first place, for what purpose does stripe pattern exist?
Suzuki Katsumi Suzuki's former professor directed the elementary school student "Sea Museum" November 2002 issue Vol.32, No.6, p.4 to 5 for FISH FOOD TIMES readers, I summarize as follows. (Including omission, deletion, text change of sentences)
In the case of vertebrate animals including fish, stripes along the body axis from the head to the tail are "vertical stripes", and those perpendicular to the body axis are "horizontal stripes". Regardless of upside down, up and down, left and right, the black stripes of larval fish of Emperor red snapper and Parrot fish are horizontal stripes, Grunt's juveniles are vertical stripes.
The role of the striped pattern is "to be conspicuous" and "to hide", and I want you to distinguish between your opponent, a friend, a bait, and an opponent as soon as possible, and to distinguish between others . For that reason it seems convenient to have a striking stripe pattern from each other.
The other purpose is, conversely, a sharp striped pattern is also useful to make the enemy's eyes deceive and hide himself. Calling this a divorced color, a noticeable horizontal stripe makes illusion to the partner, helping to obscure the outline of the fish and to avoid danger.
The horizontal stripes of a divorced color are as good as they are clear, if the color, the pattern and the edges are attached, it is better, the contrast is stronger and more prominently outstanding, the effect of erasing the outline of the fish seems to be large.
And Emperor red snapper with black horizontal stripes and Parrot fish wrapped the eyes in stripes and called it "eye masking (blindfold)". It seems that it is not good for the eyes to be conspicuous, even if you misunderstand the outline of the body with a split color, and it is not good if the line of sight does not match with the enemy carelessly, so it is to keep the eye in the horizontal stripes.
This is the adult summary of the text explained by Katsumi Suzuki, a former Professor of Tokai University.
There are still a lot of things described in detail yet, but I would like to mention one of the writers' writings about the stripes that were not mentioned there. Even though it is a huge Emperor red snapper, there is a danger of being eaten by big fish when small Juvenile fish and larval fish. Horizontal striped pattern is suitable for hiding in the same protected color as seaweed swaying at the bottom of the ocean, proportional to the fact that the risk of being gradually becoming a larger fish and eating from larger fish than himself The horizontal striped pattern is thinned. And when the Emperor red snapper becomes a huge adult fish, I think that the need for horizontal stripes that need less will disappear.
Sashimi suitable for luxury fish Emperor red snapper
Well, although the adult fish of Emperor red snapper gets very big, its white body is known for being very tasty, and it is common for fish market to trade at high price. For this reason it is more frequent to taste with raw raw fish rather than eating through a fillet. As the recommendation of the author, it is to remove the skin of the back body which is stiffer than the stomach, roasting the soft stomach body more than the back, and to do both eating methods.
To disassemble the Emperor red snapper into three pieces for sashimi in that direction, it becomes as follows.
After disassembling into three pieces, we will commercialize sashimi in the following process.

|---|---|
 |
 |
| 1, Skin side of uwami who disassembled into three pieces. | 5, The state of roasting the abdomen. |
 |

 |
 |

The same snapper(Dedemidae) companion as Emperor red snapper
Emperor red snapper belongs to the Lutjanidae family. Longtailed red snapper (Akamachi), Blue fusilier (Shicyumachi), Lavender snapper (Kurukinmachi), etc. are among the fish preferred by the fish belonging to the same Lutjanidae family in areas such as the Okinawa region and the Amami archipelago.
These Lutjanidae family fish are called machi in the Okinawa region and matsu in the Amami archipelago. These fish never become bigger than Emperor red snapper, the smallest Lavender snapper is 200-300 g, the biggest Longtailed red snapper is at most 2 kg, and the price of Lavender snapper, which is the most frequently caught, It is cheap, the catch is low and the red color is also favored the price of Longtailed red snapper is the highest price and the Blue fusilier is the middle of the two fish of size, price and catch.

In the April issue of FISH FOOD TIMES No. 13 Heisei 20, I took up about Longtailed red snapper (Akamachi). These Lutjanidae family fish are in Okinawa and Amami archipelago areas, but of course they are eaten as high grade white sashimi, but on the other hand they are often treated as fish for fillets, It can be said that it is popular fish. However, these three fish species all have a spindle shape and do not seem to be the same Lutjanidae family fish as compared with the flat shape of the Emperor red snapper.
Comparing the 4 fish species of Lutjanidae family fish, long ago it was originally the same ancestor. From what time, each one has evolved independently, it seems that the difference as now appears, it is thought that fish with better environmental adaptability to survive in the sea became bigger. In other words, the fact that Emperor red snapper, which was supposed to grow to be the most enormous, was able to blind the enemy's eyes by wearing the pattern of "horizontal stripes" in the early childhood when its survival was the most threatened, It seems that it has become power.
Even in the human world as well as in the sea, it seems that there is a common thing that "those with excellent environmental adaptability grow greatly".
