Steelhead Trout populations are dotted around various lakes, mostly in the south. Steelhead Trout respond to many types of bait, most especially worms. They are fairly large and good to eat. Bigger specimens can be quite powerful and strongly resist being reeled in. They are notably more active in rainy weather. A few hardy fishermen in the northern Roanoke Valley claim to have seen, but never managed to catch, a Legendary Steelhead Trout.
According to the compendium in game, Worms are the best bait to successfully catch trout. However, lures might be more effective in the the case there are small fishes like Bluegills or Pickerels swimming nearby, because lures will attract only trouts while be ignored by smaller fishes.
Steelhead Trout are only found in the southern portion of the map, where they appear more abundantly in the region of Lemoyne. They can also be fished in New Austin along the San Luis River.
- Steelhead Trout, along with Sockeye Salmon, are arguably the most profitable fish, because they have a good selling price as well as can be carried in a large number.
