How to catch Rainbow Trout
Use the Fishing Rod. The exact approach depends on the creature’s category and, for shore-dwellers, its species type.
- Cast the Fishing Rod into the right water: rivers and lakes for freshwater fish, coastal waters for saltwater fish.
- Wait for the nibbles, then strike when the line bites down.
- Higher-quality saltwater fish need a slow reel-in. Keep the line from snapping instead of holding the button down.
First catch: the creature is added to the Omnidex. Offer it to Mors at the Omni-Gallery to put it on display and unlock its Omnipedia entry.

Rainbow trout have significant economic value. In some well-established aquaculture regions, rainbow trout fry are aerially "bombed" into water bodies using planes to complete stocking tasks.
It seems that turning an ordinary plane into a torpedo bomber might only require a few rainbow trout.
