Get in touch with Greg Grimes here on the forum. He has a tagging system that uses just what was described. Numbered tags or non-numbered tags. I use the numbered ones. They go in the fish towards the rear of the dorsal fin, and you have to make sure the tag goes thru the rays that extend down into the fish so it "sticks" in the fish. I stuck the first tag in a fish in the early summer of 2009. I recently caught one that had the tag all covered in algae. I scraped off the algae and still could read the numbers plainly.
