Spotted Bass

Spotted Bass

Spotted Bass (Micropterus punctulatus) in Arizona are non-native fish that were introduced from their native range in the Mississippi River basin between 1942-1973, establishing populations in the Lower Verde River system and Verde River watersheds.

Scientific Name: Micropterus punctulatus

Physical Characteristics:
  • These bass are distinguished from largemouth bass by rows of dark spots below the lateral line, a mouth that doesn't extend past the rear margin of the eye when closed, and ten dorsal spines versus nine in largemouths.
  • Adult spotted bass average 18 inches and 3-5 pounds with a 6-year lifespan.

What to know

Habitat Distribution

  • Arizona's spotted bass prefer deeper, clearer water than largemouths, typically inhabiting areas with less dense vegetation and more open water with current.
  • They are habitat generalists with an affinity for rocky structure.

Key Locations

  • Verde River system where they're established.
  • Lower Verde River system and Verde River watersheds.

Specific Spots

  • Focus on main lake points with rocky transitions in 10-20 feet of water, secondary points with boulder clusters, and rocky reefs adjacent to deeper water.
  • Main lake points, areas with standing timber or brush piles.
  • Fish areas with minimal aquatic vegetation density, as spotted bass prefer open water structure over heavy cover that largemouth bass favor.

Spotted Bass FAQ

Answers from onWater's species guide.

What are the best lures and bait for Spotted Bass in Arizona?

4-6 inch straight-tail worms in green pumpkin or watermelon colors for shakey heads. Finesse worms for drop shot rigs. Medium diving crankbaits (7'-12' runners). Bladed jigs. Soft body swimbaits (small to medium). Natural shad colors, natural craw colors, and dark neutrals are most productive bait colors.

When is the best time to fish for Spotted Bass in Arizona?

Pre-spawn (52-65°F water temperatures) and post-spawn periods are best. Avoid actual spawning season (63-78°F). Spawning occurs when water temperatures reach 63-78°F (typically March-June in Arizona).

How do you catch Spotted Bass in Arizona?

Shakey heads worked slowly along rocky transitions. Dr.op shot rigs with finesse worms excel in clear water conditions. Medium diving crankbaits (7'-12' runners) worked parallel to points and structure. Bladed jigs around points and structure in 10-15 foot range.

What do Spotted Bass eat?

Spotted bass are aggressive predatory fish that feed primarily on shad, minnows, and other open water forage fish as adults, while juveniles start with zooplankton before transitioning to aquatic insects, small fish, and crawfish by 2-3 inches.

Where do Spotted Bass live in Arizona?

Arizona's spotted bass prefer deeper, clearer water than largemouths, typically inhabiting areas with less dense vegetation and more open water with current. They are habitat generalists with an affinity for rocky structure.
