What do three sablefish do over the course of 20 years? Grow a few inches, move around a bit...probably go bowling a few times

This is pretty cool:

From the Southwest Fisheries Science Center, we learn that fishermen on the U.S. west coast have recently caught several sablefish (aka black cod) that were tagged years ago in a now-defunct tagging program. Each of the three sablefish in question was first tagged over 20 years ago. Two were recovered more than 500 miles from the point of tagging,  but the third was found less than 15 miles from its tagging location.
