Some of the technology didn't work, fundamentally.
You describe very well the nature of the program, how it was supposed to work, and so on. It sounds as though I'm being flippant, but please don't take it that way, but some of the smolts didn't behave as they were supposed to. They didn't go where we thought they would, and when they got there some of the tags didn't work as well. But, that said, we learned a huge amount from it. That particular program, in the incarnation that you described, has morphed just a little bit. Essentially we're continuing to invest a fair bit in improving the technology itself so that some of the tags we put into these animals will actually work better, we think. The ocean tracking network, which is based at Dalhousie University and operates all over the world, is the key partner in that regard. As well, as I was mentioning in one of my earlier answers, we're trying to figure out what ocean conditions affect some of our modelling work. We're starting to get a much better idea of what happens to these animals as they move out of the system, but that's still a great mystery, quite frankly. When they go out to sea, it's almost like “there be dragons”. We don't know where they go and what happens to them when they get there.
