Ayu (Sweetfish) is in season from June to October.
It is known for its sweet, melon-like aroma and is often called the “Queen of Clear Streams.”
In Niyodogawa Town, Kochi Prefecture, the traditional “Tomozuri” (companion fishing) method is used to catch Ayu.
This rare fishing technique, found in only a few places worldwide, takes advantage of the territorial nature of Ayu by using a live Ayu as bait to lure and catch others.
Kochi’s Ayu has won multiple Grand Prix awards at the “Seiryu Meguri Kiki Ayu Kai” (Clear Stream Sweetfish Tasting Competition) and is highly praised both domestically and internationally.
Beyond the classic salt-grilled Ayu, it is also enjoyed in traditional dishes like “Segoshi” (thinly sliced sashimi-like preparation), “Sugata-zushi” (whole fish sushi), and “Kanroni” (sweet simmered Ayu).
Additionally, modern culinary innovations such as Ayu rice, Ayu pasta, and French cuisine incorporating Ayu have gained attention.
Amid a nationwide decline in Ayu populations, efforts are being made to protect and restore resources.
Measures include PCR testing to combat cold-water disease and river maintenance projects aimed at restoring the natural habitat of Ayu.

I’ve heard that the shogunate went as far as to issue a ban on fishing for ayu. ところで皆さんそもそもあゆのこと知ってますか
By the way, do you know about Ayu in the first place? 夏を告げる旬の川魚あゆ
Ayu, a seasonal river fish that heralds summer 川魚というイメージが強いあゆですが
Ayu has a strong image of being a river fish. 実は海と川を行き来する魚
In fact, it is a fish that goes back and forth between the sea and the river 秋に川で生まれたあゆは
The sweetfish born in the river during autumn 冬の間は海に行き動物プランクトンを食べ成長
During the winter, they go to the sea to feed on zooplankton and grow そして初夏になると再び川へ戻り
And in early summer, we return to the river again. 今度は川の苔を食べ大きくなり
This time it eats the moss of the river and grows bigger, 秋に産卵

My intuition is really buzzing right now. 甘味が強いお砂糖なめてるみたい
It’s like tasting super sweet sugar. おすすめはしません
I wouldn’t recommend it. これは本当に釣り人がが釣ってきて

Delve into the reason. なぜ高知のあゆは美味しいのか
What makes the ayu from Kochi so delicious? その理由を清流めぐり利きあゆ会の主催
The reason for hosting the sweetfish tasting event along the river tour. 内山さんに聞いてみると
When I asked Mr. Uchiyama 海まで繋がった綺麗な川が多いということだと思います
I thought that there were many beautiful rivers that connected to the sea. 高知の河川の特徴例えばこの仁淀川なんですけど
An example of the characteristics of rivers in Kochi is the Niyodo River. 放流量の100倍から1000倍のあゆが
100 to 1000 times the discharge rate いる
Necessary つまり釣れてる魚の９割以上が天然遡上あゆ
In other words, more than 90% of the fish caught are natural upstream ayu. っていうのが高知の特徴だと思うんですよね
I believe that’s one of the characteristics of Kochi. 全国で天然遡上あゆがのぼる100河川
100 rivers across the country where natural ayu fish migrate upstream. っていうのを調べたんですけど
I looked into it. そのうちの10河川は高知県なんですよ
10 of them are in Kochi Prefecture 天然遡上がのぼる河川だけでも10個あるんで
There are at least 10 rivers that flow upstream naturally. それを10種類集めると10種類の味が楽しめますよ
If you collect 10 of them, you can enjoy 10 different flavors これやっぱり魅力ですか
Is this really appealing? 魅力ですね
It’s a charm 人工的に種付けしたあゆを春先川に放流する
Artificially seeded ayu is released into the river in early spring 放流あゆと
Release Ayuto 海から帰ってくる天然遡上あゆの2種類に分けられる

In Kochi Prefecture, there are more than 10 rivers where such natural ayu returns. あゆが戻ってくるのは綺麗な水質だけではなく
Ayu return not just because of clean water quality. これ見てください
Take a look at this 元々はこれはこういう色なので
This originally comes in this color. 茶色いのがあゆのエサになる苔です
The brown moss serves as food for sweetfish. 綺麗な水で流れが割と早いので
Since the water is clear and flows quite fast. 古くなった苔はどんどん洗い流されて
The old moss keeps getting washed away. 新鮮な苔が生える
Fresh moss is sprouting. 水が綺麗ってことは底まで日が入りますので
Clear water means that sunlight can reach the bottom. 新し苔がどんどんどんどん生えてくる
The new moss is growing rapidly. エサとなる川底の岩に付着した苔も大切な条件
The moss growing on the rocks at the riverbed is also a crucial factor as it provides food. 全国的にも高知の河川の苔は新鮮だという
It is said that the moss in Kochi’s rivers is fresh even nationwide そのため高知のあゆは特に香りがよく
That’s why the ayu from Kochi is especially aromatic. メロンやスイカのような甘い香りがするんだそう
They say it has a sweet fragrance reminiscent of melons and watermelons. そんな高知あゆはこの道の駅でも
You can also find this Kochi sweetfish at this roadside station. 年間6万匹ほど販売するという人気ぶり
It is so popular that it sells about 60,000 animals a year 家庭の冷凍庫にストックが

From the pages of a fishing enthusiast’s diary 一応浜ちゃんのモデルって言われてます
They’re saying that Hamachan is considered a model. 浜ちゃんのモデル？
Is that Hama-chan’s model? 半分本当で半分違うかな
I wonder if it’s half true and half false. 大体あんなに頻繁に合体しないので
They don’t usually merge that often. 小学館で雑誌編集者として
Working as a magazine editor for Shogakukan. 第一線で活躍していた黒笹さん
Mr. Kurosasa was active on the front lines あまりに釣り好きだったため

It appears they are still enjoying ayu fishing. 釣って面白い
Fishing is fun. それから食べて美味しい
And it tastes delicious after eating. 県全体として美味しいあゆのボリュームが
The prefecture is known for its abundant and delicious sweetfish. 大きいのはやっぱり高知かなと思います
I believe Kōchi is probably the biggest one. 僕は釣りの神様に選ばれた土地は高知かなと
I think the land chosen by the god of fishing is probably Kochi. よそから来る人はみんな高知はカツオでしょう
Everyone who comes from elsewhere will find skipjack tuna in Kochi っていうだけであって
It’s simply stating that. それ以外にも美味しい魚いっぱいあるのに
There are so many other delicious fish out there! 僕はあゆにとにかく光を当てたいということで
I just want to shine a light on Ayu 今いろいろ活動してます
I am currently involved in a lot of different activities. あゆ王国高知振興ビジョンですね
This is the vision for promoting the Ayukoku Kingdom in Kochi. 一つはそのカツオばっかりに偏らない

A major initiative to promote the unique appeal of ayu from Kochi. その取り組みとは
What initiative are you referring to? いろんな漁業さんの協力をいただいて
We are receiving support from various fisheries. 去年初めてやって
I did it for the first time last year. 正直こんなに反応があるとは思わなかったので
To be honest, I didn’t expect such a reaction. あゆの美味しさを広めるため
To promote the delicious taste of sweetfish 県内から1000匹以上の天然あゆを集め
Gathering more than 1000 wild sweetfish from the prefecture 料理を振る舞う高知天然あゆまつりを開催
Kochi’s Natural Sweetfish Festival serves up delicious dishes. 4000人以上の来場者があゆ料理を楽しんだ

Moreover 海外の食品見本市みたいなところに出店をして
Setting up a booth at an overseas food exhibition. 外国人に食べてもらって
I want foreigners to try this food. 大変に評価は高かったと
It was reported that the evaluation was extremely positive. 国際見本市やドバイの食材フェアへ
To the international trade fair and the Dubai food fair. 高知のあゆを出品
Selling ayu from Kochi. その味が評価を得るなど
That flavor is gaining recognition. 高知のあゆは世界でも注目されつつある
Kochi’s ayu is attracting attention worldwide. 地元高知の老舗ホテル城西館でも
Even at the long-established hotel Joseikan in Kochi あゆ料理にある進化が
The evolution of ayu dishes is やっぱりあゆって塩焼きが定番じゃないですか
Isn’t grilled ayu with salt the traditional way to enjoy it? そこでまた違った料理をあゆの良さをアピールしたい
I want to showcase the unique qualities of ayu through various dishes. そこで始めたのが新鮮なあゆを
What began there was the fresh ayu. 四万十名物ぶしゅかんの果汁で締めて作る
This dish is made by finishing it off with juice from the local specialty bushukan found in Shimanto. あゆの握り

And the chef himself devised Ayu no Yayaki, etc. ここでしか味わえない新たなあゆ料理が
A new sweetfish dish that you can only enjoy here. 作ってみてやっぱり一番美味しかったんで
When I made it, it was the most delicious それはね皆さんに食べてもらいたいという
I really want all of you to try it. しかし今あゆには大きな問題が
But now Ayu has a big problem それがあゆの漁獲量
That is the amount of sweetfish caught. 全国で最盛期と比べおよそ10分の1まで
Up to about one-tenth of the peak in Japan 低下してしまっているのだ
It has indeed declined. その原因が
That’s the reason. 病気の問題でですね漁獲量が低下しています
The volume of fish caught is declining due to health issues. その病気って何かというとですね
What is the disease? 冷水病というバクテリアの感染症なんですけれども
It’s a bacterial infection known as cold-water disease. それがですね全国の河川に蔓延して
This is spreading across the rivers nationwide. 漁獲量がですね全国的にですねぐっと減っていく
The fish catch volume is significantly decreasing across the country. 全国の河川で冷水病が発生
Cold water disease has been reported in rivers across the country. その結果あゆの漁獲量が著しく低下
As a result, the catch of ayu has dropped significantly 減りゆく資源を守るために立ち上がったのが高知県
Kochi Prefecture has taken a stand to protect its dwindling resources. その取り組みとは
What does that initiative involve? PCR検査っていうのをやってます
We are conducting a PCR test. あゆのPCR検査？
Ayu’s PCR test? 一体それは？
What the heck is あんまりですねその感染症対策を意識したような
I don’t think they’re very aware of infection control measures. 放流っていうのがなされてないってのが現状です
The current situation is that there is no such thing as discharge つまりだから放流するときにですね
In other words, that’s why it’s time to release it この場所のこういう時期には病気が出やすいから
It’s easy to get sick at this time of year in this place ここの放流を避けようとかですね
We should probably try to steer clear of the release here. そういったことを今後取り組みとして入れていくと
We plan to tackle these kinds of issues in the future. 河川での病気の被害ってのが
The impact of diseases in rivers is 減ってくるんじゃないかなっていうふうに個人的な
I think it’s going to decrease. 考えです
It’s an idea 他にも国と協力しあゆを守る取り組みをする方も
There are also people working together with countries to protect ayu. こんちには
Hello. はいこんにちは
Hello. よろしくお願いします
Thank you in advance. どうぞよろしくお願いします
I look forward to working with you. 物部川漁業協同組合の松浦さん
Mr. Matsuura of the Monobe River Fishery Cooperative Association やっぱり石ですね
After all, it’s a stone あゆを釣るには石を釣れと言われるぐらい
It is said that in order to catch ayu, you have to catch a stone 石とあゆの関係ってのは切っても切れない
The bond between stone and ayu is unbreakable. 水質もさることながらやっぱり川の形
In addition to the quality of the water, the shape of the river その形を構成するのは石とか砂とか
The shape is made up of materials like stones and sand. その中でも特にあゆのエサ場となる
Among them, it is especially a feeding ground for ayu 大きな石がどういうふうに
How the big stone looks ゴロゴロ転がってるかっていうのが
Is something just rolling around? あゆにとっては非常に大事な環境です
This is a very important environment for Ayumi. あゆにとって大事なエサ場となる川の中の大きな石
A large stone in the river that serves as a vital feeding ground for Ayu. しかしダムが三つもできたこちらの物部川では
However, in this Monobe River, where three dams have been built, 上流から石が流れなくなり
The stones have stopped flowing from the upstream. あゆが育つ環境が減ってしまった
The habitats for ayu have been declining. そこで松浦さんは河川を管理する国に掛け合い
So Mr. Matsuura called on the country that manages the river. ダムでせき止められた石を川へ搬入
Stones that have been trapped by the dam are being transported to the river. 河川整備を行い
Implementing river maintenance. あゆが育ちやすい環境を戻す取り組みを実施
Taking actions to restore a favorable environment for the growth of ayu fish. さらに大きな石だけでなく小さな石も川へ
In addition, not only large stones, but also small stones go to the river その理由は
What is the reason for that? 実はこういうね1センチから5センチぐらいの
Actually, it’s like this, about 1 cm to 5 cm これくらいの小石があゆは卵産みやすい
Ayu fish find it easier to lay their eggs on small stones like these. あゆは砂利や小石が多い場所に産卵する習性を持つ
Ayu fish tend to spawn in areas rich in gravel and small pebbles. これにより石の隙間や砂利の隙間に入った卵は
As a result, eggs that have entered the crevices of stones and gravel 外敵から守られる
Protected from outside threats そのため物部川では
Therefore, in the Monobe River あゆの産卵に適した細かな石を
Fine gravel ideal for spawning ayu. 河口付近に大量に置いたのだ
I put a lot of things near the river mouth. 全国的にね高知県もそうですけども
Nationwide, Kochi Prefecture as well あゆの漁獲量はどんどん減ってきてます
The catch of ayu fish is steadily declining. 様々な要因があるでしょうけど
There could be various factors at play here. 川の形とかそういった川の環境の
The shape of the river and its surrounding environment 占める割合も大きいんで
It takes up a significant share. そういったのを河川管理者とこういう形で
Working with the river management authorities in this way. 協力しながら最適解を見つけていくのが
It’s about finding the optimal solution together. 大事だと思うんです
I believe it’s really important. その結果はあゆが出してくれます
Ayu will provide that result. 高知の人に古くから愛されてきたあゆ
Ayu has been loved by the people of Kochi for a long time あゆの資源回復の取り組みはまだ始まったばかり
The efforts to restore ayu fish resources are still in their early stages. 焼けました
It’s done baking. 未来に高知のあゆを残したい
I want to preserve Kochi’s ayu for future generations. カツオもいいけどあゆもいいよ
Bonito is good, but Ayu is also good
