Yellow Perch


Yellow Perch

Yellow Perch are an introduced species in California, first successfully stocked in 1891 when 6,000 specimens from Illinois were placed in Lake Cuyamaca and the Feather River.

They're now established in multiple California watersheds including the Sacramento, Klamath, San Diego, and Kern regions.

Scientific Name: Perca flavescens


Physical Characteristics:
  • These elongated, laterally compressed fish are golden yellow with 6-8 distinctive dark vertical bars on their sides, two separate dorsal fins, and can reach up to 20 inches, though 7.5 inches is more common in California waters.
  • California populations rarely exceed 5 years of age or grow beyond 12 inches, with fish over 30cm or 0.4kg being rare in the state.

What to know

Habitat Distribution

  • Yellow Perch are most abundant in the weedy backwaters of rivers, shallow lake areas, and large ponds, preferring warmwater situations with heavy vegetation.
  • They're now established in multiple California watersheds including the Sacramento, Klamath, San Diego, and Kern regions.

Key Locations

  • California waters like Iron Gate Reservoir, various reservoirs in the Sacramento Valley, Klamath system, and mountain lakes where they've been successfully introduced.

Specific Spots

  • Look for them around heavy vegetation, submerged structure, and in 1-10 meter depths near plant beds.
  • They form loose schools above beds of heavy plant growth in 3-33 foot depths, with immature fish forming tighter schools in open waters 3-13 feet deep.

Yellow Perch FAQ

Answers from onWater's species guide.

What are the best lures and bait for Yellow Perch in California?

Small jigs are highly effective - try 1/32 to 1/8 ounce jig heads tipped with 2-inch curly tail grubs, small swimbaits, or live bait like waxworms, nightcrawlers, or small minnows. Small spoons, spinners, and crankbaits like the Rebel Hellgrammite also produce, especially the larger fish.

When is the best time to fish for Yellow Perch in California?

Spring and early summer months when they're most active. Spawning period should be avoided by anglers to protect reproduction (April-May in California when water temperatures reach 45-65°F).

How do you catch Yellow Perch in California?

Use a slow, steady retrieve or a yo-yo technique - cast out, let the lure hit bottom, then lift it with short, deliberate rod movements from 9 to 12 o'clock position. A tandem rig with two jigs 12-18 inches apart can double your chances.

What do Yellow Perch eat?

Their diet shifts with age - juveniles feed on zooplankton, while adults become benthic specialists browsing plant beds for large invertebrates like crayfish, dragonfly larvae, and snails, plus small fish including salmon when available. Feeding occurs primarily at dawn and dusk.

Where do Yellow Perch live in California?

Yellow Perch are most abundant in the weedy backwaters of rivers, shallow lake areas, and large ponds, preferring warmwater situations with heavy vegetation. They're now established in multiple California watersheds including the Sacramento, Klamath, San Diego, and Kern regions.
