Fishing Upgrade Angler

Before fishing, may spend 3 gold to catch any fish in current location.

I first read this to be just pay 3 gold and pick 1 fish put now I'm wondering if you gain all the fish on the track for the location you're fishing from?

It's one fish. Just lets you catch something without rolling for it, so it can be useful for legendary fish!
