Computers that you deploy on fish, like you would with a conventional tag.
But he's got to break surface to make it ping.
No, it's not true.
So let's go back to what conventional tagging looked like.
You would catch a fish in Kona, Hawaii, and maybe somebody, luckily, if ever, might catch that fish some other location.
The data you got from that was minimum, days at large.
How long has that fish been swimming since it was caught and it was recaptured?
And then you would get a linear distance from point A to point B. You don't know what that fish did in that period of time.
And you didn't know anything about its diving behavior.
Starting in the- Yeah, he could have went a lot farther and been on his way home when he got caught.
Yeah, absolutely.
In the late 90s, 2000s, these PSATs, as they're called, started to come on the scene.
And they collect a wealth of data.
You know, every 30 seconds you're getting information on temperature, depth.
You're able to get an algorithm based on light to determine a daily fix of these fish.
So you're able to get a track of where these fish go.
It doesn't.
It can't.
So what happens is you program that tag to stay on that tether for a predetermined amount of time, usually between 180 and 240 days.
Okay.
