Those devices are supplied specifically and are tailor-made for bluefin tuna. They're satellite tracking devices. The tuna doesn't have to come to the surface to breathe. Every time they do come to the surface, the information is downloaded through a satellite. That's then tracked through Canadian parts in New Brunswick.
With a mammal that has to come to the surface to breathe all the time, every time they come to breathe, you're actually getting a real-time track and a hit. With today's technology, that should be easy to download to any of our vessels on a real-time basis.
