White Bass
White Bass were originally introduced in 1960. They have a silver-white body with 4 to 7 dark horizontal lines. Lines below lateral line are often faint and broken. Dorsal fins are distinctly separate and 2nd anal spine distinctly shorter than the 3rd. Their lower jaw protrudes beyond upper jaw.
Average Length: 8 to19 inches.
Average Weight: 5 ounces to 4 pounds.
Habitat
Found only in Imperial Reservoir on the Colorado River and Lake Pleasant. White Bass prefer clear, open waters. They spawn in large groups, in April or May, generally over rocky or rip-rap type areas.
Diet
A White Bass's diet in Arizona mostly consists of threadfin shad. Hungry white bass will often pursue schools of shad, causing the shad to jump and "boil" the surface of the water in their frantic efforts to escape.
