Nikko Sashi seems to be the correct name for what I had called Nikko Maggies. The new packaging clearly says サ シ (sashi) . Even
the old packaging said sashi, but it wasn't clear that was the name. I got the "Maggies" name from the Nikko website (which now calls them Fly Larvae SS). I think I'll call them Sashi.
Do not believe the Urban Dictionary, which says sashi stands for "super attractive stylish hippie intellectuals." Sashi are blowfly maggots. (That is not to say that hippie intellectuals are maggots, but that's what sashi means in Japanese.)
The Nikko Sashi are biodegradable artificial maggots. They are very effective for panfish and for micros when you don't have live bait. I have tried a lot of things for micro bait, and while the best seems to be the smallest speck of earthworm you can cut, some people do not like to cut up worms. Even if that doesn't bother you, sometimes you just don't have a worm to cut.
What got me searching for alternatives was the sheer waste of buying worms for microfishing. One worm is more than enough for a full day of microfishing, but what do you do with the rest of them? For some reason, my wife was not thrilled to have worms in the refrigerator. I tried bits of chicken and even steak! (Pound for pound, cheaper than worms!)
I have not yet tried them for trout, although I know live maggots are used quite effectively in the UK. One of the participants at the first Midwest Tenkara Fest was a bait fisherman who said essentially that you wouldn't believe how effective maggots are for trout. One of these days I'll have to give it a try.
I have also tried things as simple as a knot of yarn tied around a tanago hook, but micros are even faster than trout. They hit it, but they spit it so fast I couldn't hook them. I have had much better luck with bits of scented plastic baits. They will still spit them out, but not nearly as quickly.
Several years ago, while visiting my supplier in Japan, my wife
picked up a package of Nikko Sashi (what I called Maggies). The packaging then said "Zazamushi," which
loosely translates to shallow water insect larvae, and Wakasagi Sashi. Wakasagi is a smelt generally caught while ice fishing. Sashi are blowfly maggots. Although wakasagi is the species people use Nikko Sashi for in Japan, here in the US, I suspect micros and sunfish will be the primary quary.
The new packaging also says "Nikko Worm" but the packaging for several other Nikko products (that aren't worms) says "Nikko Worm."
I sent some of the Sashi to Ben Cantrell to try as a micro fishing bait. He took them on his recent trip to Mexico and when he returned told me "They worked great when we didn't have any live bait. Which was 90% of the time. Seriously, they worked really well." A number of the other fish he caught with the Sashi can be seen on his Flickr page.
When he told me how well they had worked, I knew I had to get some in for the shop. After all, if there are any micro fishing masters in the US, Ben has to be one of them. Luckily, I was able to track down the Nikko Sashi (maggies) and I think I bought the entire remaining supply (in the old packaging). It did not take very long before they were gone.
I am happy to say the Nikko Sashi are back in stock.
I have them in white, which is probably the best color to use when sight fishing. I find it easier to see white than any other color with the stream bed as a background.
The Nikko Sashi come in five strands with 10 sashi per strand. You can tear them from the strand one by one, but for smaller micros you may even want to cut them in half. The plastic is quite durable and will last for lots of fish.
Despite being durable, sashi are completely biodegradable and contain no plastisol, phthalates or any toxic chemicals. (Unlike the hippie intellectuals back in Boulder, CO in the early '70s, many of whom were heavily into chemicals.)
Domestic shipping is $4, via USPS First Class Mail (unless ordered with an item that must go via Priority Mail, and which has a higher shipping charge).
The charge for international shipping depends on the destination country, the weight of the package, the overall length of the package and the value of the package.
