Fishing Rod

The clearest evidence is an on-screen message captured as Jason flies over open water: this is a fishing spot for large Common Snook, equip a fishing rod to try and catch one. A named, real Florida gamefish implies a species catalogue, and a required rod implies a tool you acquire and carry.

Inventory footage from the same wave shows the rod occupying a utility slot alongside the Flashlight and Binoculars, so it travels with you rather than living at a pier. Rockstar’s own Extended Look montage includes fishing footage, making the activity official even while the item itself stays leak-sourced; the wider picture lives on the Fishing activity page.
