The G5 Fish Tag, more on RFID
Now there is a way to track those wayward salmon on their journey into the trackless expanse of the North Pacific Ocean. Maybe. The Brits have come up with a device, after working on it for 20 years, that we might want to try. The problem we have had was brought home this summer when runs up and down the coast failed to show up. And nobody could say what happened to them because nobody knows where they go.
Of course you have to have a pretty good map of the ocean in regards temperature at various depths all over. For all I know the Alaska Department of Fish and Game is "on it" already. How is it that I don't believe that though?
The ADF&G used to catch some salmon coming into Southeast Alaska and stick them with a tag that looked like a little airport locker tag. The idea was to see which stream they were heading for. I found a humpy packing one of these tags in a stream on the north end of Kuiu Island one year. I sent it in and got all of a dollar as a reward. Fishermen would have to send in the G5 tag too. Hopefully the reward would go up.
Here's more information on RFID tags too. I saw a presentation on this at Fish Expo. in Seattle recently. Monitoring fish shipments is starting to go high tech. and there's no turning back probably. The information gathered this way is invaluable IF the shipper and everyone down the supply chain remains dilligent about keeping the seafood in pristine condition.
A valuable piece of this article is a hyperlink near the end of the article labled "sensors" that links you to a glossary of RFID terminology. In fact the website is called "RFID Journal" and looks like one to bookmark for future reference.
