There were some questions earlier on the Salish Sea program. There was one program there a few years ago that I heard about. I think the acronym was POST. It was an underwater radio receiver system in which they would actually implant radio transmitters in the outgoing smolts and record where those smolts travelled up the coast. The transmitters would shut off for two years while they were at sea and then turn back on and record where they returned.
Is that program still running? It seemed to be a very valuable tool at the time.
