To fish in Fallout 76 (which seems to be the intended reference as there is no "Fallout 7" game), you need to start by unlocking the fishing mechanic via the Casting Off questline introduced in Season 21: Gone Fission. Here are the basic steps:
- Tune your Pip-Boy radio to the Linda-Lee frequency to find the Casting Off quest.
- Go to the Mire region on the map to the Fisherman's Rest area.
- Talk to NPCs like the Fisherman and Captain Raymond Clark to get your first fishing rod and bait.
- Approach any body of water and look for the fishing option in the interface.
- Hold the fishing button to cast your line.
- Wait for the bobber to be pulled underwater by a fish, then reel in using the joystick/stick to keep the fish in the highlighted area until caught.
- Bait is required and can be bought from the Fisherman or crafted.
- You can upgrade your fishing rod and use different bait types to improve results.
- Cooking fish bits and feeding a character named Linda-Lee can give special rewards.
This fishing mini-game includes catching different fish, axolotl, and fishing rewards through quests and cooking.
If "Fallout 7" was meant differently, please clarify, but currently, the latest Fallout game with fishing is Fallout 76.
