Seriously, this article really caught my attention. Bar codes on fishes? Definitely a new tagging system I've not heard of until now.
Most of us are familiar with bar codes, those small black stripes with numbers below, known as the Universal Product Code or UPC label, that appear on commercial products. We scan them at the grocery store or to check a price, or have to cut them out and send them in for a rebate.
Now imagine scanning a DNA barcode on the piece of fish you just bought for dinner to instantly verify the species, where it came from, its nutritional value, and other valuable information. NOAA researchers are helping to make this scenario a reality.
Maybe they can be used at the supermarket checkout counters too! :P
