Completely Farm-Bred Unagi, a World First

JoshuaInNippon writes "Japanese scientists at the National Research Institute of Aquaculture, Fisheries Research Agency have reported that they successfully completed an artificial cultivation cycle for unagi, or eel — a world first. Unagi is a traditional delicacy in Japan, and can commonly be found in baked form at sushi restaurants. The fish has long been caught either matured, or still young and then fattened on farms. Sadly, as a result, natural stocks of unagi have plummeted in recent years. However, the research news indicates a future method to completely farm breed the tasty creature in mass quantity. Good news for sushi lovers, Japanese businesses, and wild eel alike."

    In the US Pacific Northwest, it has been found that farm raising salmon significantly hurt the wild populations.

      The AC is probably referring to the infections that the farmed salmon have transmitted to nearby wild populations. I don't know if transmission is via escape or simple proximity, but there has been some noise about the issue.

      Just like with the meat industrial complex animals, the farmed salmon require high doses of meds because of the unnatural and crowded living environment, and this has resulted in some aggressive infections for which the wild population is unprepared.

      Or the genetic impacts on wild salmon (naturally selected for overall fitness) of interbreeding with escaped farmed salmon (human selected for fast growth rates). It's actually a fairly nasty problem for wild stocks, and is being extensively researched.

    And what will these eel eat? Oh, that's right - fish. Which have to be caught and then fed to the eels...

    Salmon farm fishing is a disaster. Shrimp are not much better. I don't know how the tilapia production is fairing. Tilapia are not predators like salmon, so I imagine it might be better, but I have no idea.

    Answer: stop eating fish. Sorry.

      Which is why they taste like water....

      Seriously, I know that tilapia are "environmentally friendly". However, they taste like shit. Give me pretty much any other fish, and I'll be happy. Tilapia are the shittiest fish you can get.

      This kills me, because I'd like to be environmentally friendly, but when given the choice of "tastes like water, and falls apart", and is fucking amazing I'm hard pressed to want to choose tilapia. I want to be good, but tilapia makes me hate fish, more than any other fish. It's so sad that the good-for-the-environment-fish taste like crap.

      Fish farming isn't a disaster at all.

      Sure, the fish have higher levels of stress and disease. But that doesn't matter since we're going to eat them anyway and we won't catch their diseases.

      Sure, the fish live at higher densities than seen in the wild. So what? Doesn't affect their taste.

      Sure, the fish have higher levels of lice. That's a problem if they infect wild populations. So that's adequately and properly solved with a greater distance between the two.

      Sure, the fish are sometimes fed too many antibiotics. Solution? feed them less! It's just an equation between antibiotics and profitability. It'd be fine to pay a bit more in exchange for a bit less antibiotic use.

      Sure, the fish cause pollution from their feces etc. But that's no problem in places of high current.

      I love fish, and almost all the dishes I cook with them the taste difference between wild and farmed is minimal. And even though the farmed and quite as healthy for you as the wild, they're still pretty darned healthy.

    Funny you mention that.

    Unagi is horribly expensive ($18/US per package) if you want the Japanese-sourced unagi. The Chinese unagi is much cheaper ($4-5/US per package), but there have been problems with the chemicals, antibiotics, and other crap they feed them.

    Anago is readily available here in Los Angeles at a moderate price, but unagi kabayaki is definitely where its at.

    Which has what to do with eel? Eel is fucking delicious. Its not even "weird." Its just a long thin fish fillet.

    For what its worth, Eel consumption is also rather common in any area of Europe where Eel happens to be found, its not at all some "crazy" unique Japanese thing.

    Actually I should clarify, because I wasn't being quite honest or accurate in my previous post. The invasive species in the South East U.S. is a different species than the eels in question in the article. The pest fish that escaped the farms is the Asian Swamp Eel. While it is often sold as "unagi" and is somewhat analogous in flavor, the specific eel in question is the Japanese Eel, which does not live in the Western Hemisphere. The Asian Swamp Eel is actually from a different taxonomic order.

    The closest analog in the Western Hemisphere is the American Eel, which is also endangered, partly due to the invasion of the Asian Swamp Eel.

    That said, the Asian Swamp Eel works perfectly fine in similar roles, and is quite tasty. Unfortunately you can't really call it "unagi" in a respectable Japanese fish market, even if it's called that when sold in many fish markets outside of Japan.
