Quality and star rating both affect the sale price. MAX-size catches have a glowing aura.

Use the Fishing Rod. The exact approach depends on the creature’s category and, for shore-dwellers, its species type.

  1. Cast the Fishing Rod into the right water: rivers and lakes for freshwater fish, coastal waters for saltwater fish.
  2. Wait for the nibbles, then strike when the line bites down.
  3. 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.

Habitat: Coastal Waters. Distribution: Islets — this is an islet specialty, so plan it into a Starsea Voyage rather than a planet sweep..

Season: Year-Round. Time: Nighttime. Weather: Any Weather. If two of those tags are restrictive, check the creature tracker before you set out.

Bluefin Tuna have a unique body structure that causes them to "suffocate" if they stop swimming.

From a land-dweller's perspective, the "all gas, no brakes" lifestyle may seem exhausting, but research on Bluefin Tuna habits shows that "acquiring" this perpetual motion is exactly what it wanted all along.
