The Emperor's New Fish

The International Herald Tribune is reporting that the Emperor of Japan is expressing much regret over his decision to accept a gift of live bluegill (Lepomis macrochirus) from the United States. He brought the fish home in 1960 and, with the hope that he could cultivate them as a food fish, gave them to Japan's Fisheries Agency. Researchers there then bred the fish and released many of them into Lake Biwa. Unfortunately, bluegill numbers eventually got out of hand, and the native fauna of the lake has since declined. With peak populations of the non-native fish topping 2 million in 2002, Japan has been forced to spend millions of dollars removing bluegill from the lake.

Tip of the virtual hat to the annotated budak for sending in a link to this story.

Plant Invader 600!


Plant Invader 600!
Originally uploaded by urtica
It's the Plant Invader 600! It slices, it dices, it identifies your invasive plant...if you live in Japan anyway.

When photographer Koichi Watanabe visited me last weekend for a tour of local Japanese knotweed sites, he brought along this book to show me an example of a Japanese guide to the weeds in their country. Now I want a copy...badly...even though I do not read Japanese.

Plant Invader 600 is everything you wish your local plant field guide could be: portable, flexible, sturdy, and full of over 1500 excellent glossy photos for 600 different species, including 300 images of seeds. The scientific names are in English, and there is a lot of Katakana in there as well, so I will be able to translate some of it on my own.

Luckily, I've managed to find it over at Amazon.jp. Shipping is going to be almost half the cost but it will totally be worth it, just to see all the American plants in there :-).
Update 7/16/07: I already received my copy, and it is truly awesome! Two thumbs up to DHL and to Amazon Japan, who has our American butts kicked in the minimalist packaging department (one extremely sturdy brown envelope, no box, no tape, and none of those stupid plastic air pillows).

If I Could Buy Plants In A Bottle...

...The first thing that I'd want to do
is spend every day asking what plants they were
and if they're invasive, I'd bid them adieu!
Via boingboing, news of a store called dirty microbe selling a "Tokyo Micro Garden," which is a tiny jar with a tiny plant growing in a nutrient goo. Its meant to hang off your cellphone strap and it's darn cute. Part of me wants to buy one, I think it's that same part of me that thought it would be fun to have one of those hermit crab necklaces...the ones with live hermit crabs in them.

But seriously folks, there's this thing called "Corporate Responsibility" and the world needs more of it. It means you don't get to stick unknown plants in a jar and sell them all over the world without thinking about what species they are and whether they could potentially be invasive, and whether you might be breaking the laws of all those countries you're offering to ship to if you sell said plants there. If those plants aren't invasive, then you should be informing us, the consumer, that you've gone and checked into it.

I've emailed dirty microbe to ask them if they know what species of plants those "blue leafy" and "pink leafy" ones are, so I can check what their origin is and whether they are invasive (in the US or anyplace else). If I find out anything more, I'll post it here.

Update: Whew! I decided to do some sleuthing and I just found this page from a Japanese company that seems to be selling the exact same product. The "leafy" plants appear to be...Orchids! Specifically, Cattleya and Oncidium. So these are likely just tissue cultured orchids (and cacti too). I feel better now. I still think dirty microbe needs to put that info on their website though.

Update 2: dirty microbe has the fastest, nicest customer support staff of any webstore I've ever contacted <3 <3 <3. They assured me the plants-in-a-jar were approved for import and they promised to look into exactly what plants they were. I can see other parts of their website where they have specifically responded to customer comments and that is promising. This is a good thing - we all benefit from being better informed about the things we "consume."

Update 3: Uh oh. I was perusing dirty microbe's ultra-cute site and I just found these micro-seaweed cellphone strap attachments - algae from Japan in an unsealed bottle. There are other online stores selling these little cellphone charms too. Now I am worried again. The algae listed are: Wolveryponica, Wolverineza, Wolveritusa, and Valornia. I think Valornia=Valonia, which is sometimes listed as a nuisance species...but who knows what species this is. The others seem to exist only as trade names, I will try to figure out what their scientific names are...

Update 4: dirtymicrobe.com has been really great about this. Customer Support let me know that they are very concerned about the possible negative environmental impacts of this and they have pulled the items from their catalog pending more information (they were out of stock and expected to arrive this April). Meanwhile, if you think you might know the identity of any of those algae, drop me an email (use the Suggest a Post link in the top left corner of this page).

Update 5: The strapya-world website has more information along with better close-up photos of the algae, which they say are cultivated in deep sea water (water from more than 200 meters (650ft) below sea level).

Something Doesn't Smell Fishy

In what is perhaps the epitomy of innovation, a group of Japanese companies has come up with a unique way of dealing with the invasive black bass (Micropterus sp.). As reported by Daily Yomiuri, the companies have worked together to perfect the process of carbonizing the fish - in other words, they're making bass charcoal. The charcoal is used as a room deodorizer, with the label "We no longer eat crucian carp and ayu sweetfish, just odors."

They Make Great Pets Pests?

Japanese pet-owners are apparently having a hard time adjusting to the country's new Invasive Alien Species Law, set to go into effect this June. According to this report from Daily Yomiuri, owners of snapping turtles (Chelydra serpentina) are frantically searching for places to bring their turtles once owning them without a permit becomes illegal. Pet snapping turtles? Yikes. There's a reason for that common name. Hopefully this new law will not backfire by leading to massive releases of non-native turtles into the wild.

Last month Japan came out with the country's first official list of invasive species.
