There are a couple of different companies here that now sell.... There's a company called Vemco Amirix that produces tags that go on fish and receivers that pick up the signals emitted by those tags, so that we can track fish around the world. This company, which began as a spin-off from Dalhousie in somebody's garage, now has several European markets for these tags, largely because people become involved in our network and they use the same tags and receivers as we're using. This is an example.
The company has expanded and developed their tags and receivers, because as the science goes forward, the scientists of course always demand the “next step better” pieces of equipment. So by working together, science has developed the equipment, and it has marketed it internationally to a set of people in an international network reaching around the world. There are several lines of these receivers and tagged marine animals in Europe.
We know that the tuna off Cape Breton travels back and forth across the Atlantic a few times in the summer.
