Appearances
Think about Central America.
Their iconic billfish there is sailfish.
If you want to take somebody to catch their first sailfish, you're going to Costa Rica, you're going to Guatemala.
There has never been a stock assessment done on Pacific sailfish.
Really?
Yeah.
How would you do that?
You've got to have a lot of baseline parameters.
You've got to have things like growth.
So you have to have an idea of how fast they grow, how long they grow over time, age of first maturity, things like that.
Then you have to have some good indices of abundance, you know, where you're getting, you know, historical and current catch, you know, and effort rate.
So you can see how.
you know, the catch of things fluctuate over time.
And it's a very sophisticated thing, you know.
A little bit, but really a lot of the abundancies come from longline boats, you know, because the data is so good.
You know, there are some recreational indices of abundance that are used in the U.S.
for stock assessments, but a lot of it comes from longline data.
Got it.
And no one's been able to do that.
No.
