Identification help
Not sure what aquatic species you found?
Use each guide to compare body shape, markings, habitat, and official agency references. Color and markings can change with age, season, water clarity, and spawning condition.
Identification guidance does not replace current regulations. Seasons, harvest rules, bait restrictions, protected-species requirements, and emergency closures can differ by water and change during the year.
