Conservation reminder

Doctor fish; thrives in vegetated water.

Seasons, size limits, and keep rules vary by water. Verify the current local regulations before keeping a catch; release it carefully when unsure.

Identify and log the real catch

OmniDex identifies a live catch, estimates length, and saves a private city-level journal entry without exposing raw coordinates.
