White Perch


White Perch

White Perch are an invasive species in Indiana, first recorded in the state in 1998-1999 in Lake Michigan and Little Calumet-Galien watersheds.

Despite their name, they're actually temperate bass relatives rather than true perch, closely related to striped bass.

They've been illegally stocked by individuals in inland Indiana lakes and are considered highly problematic due to their aggressive feeding habits.

Scientific Name: Morone americana


Physical Characteristics:

These silvery fish typically measure 7-10 inches and weigh under a pound, with a distinctive humped back and no horizontal stripes.


What to know

Habitat Distribution

In Indiana waters, they prefer shallow areas (6-12 feet deep) with little cover and muddy/silty substrates, though they can be found as deep as 360 feet in some waters. Outside of spawning, they school heavily and move between deep winter refugia and shallow feeding areas.

Key Locations

Target them in Lake Michigan along Indiana's shoreline, in Cedar Lake where they're abundant but small, and in various inland lakes where they've been illegally introduced. Key locations include Burns Ditch near the Port of Indiana, various Lake Michigan access points, and Cedar Lake.

Specific Spots

Focus on structure like drop-offs, sunken logs, brush piles, and creek channels, especially in 10-39 feet of water.

White Perch FAQ

Answers from onWater's species guide.

What are the best lures and bait for White Perch in Indiana?

Top baits include nightcrawlers (broken into quarter pieces), grass shrimp, small minnows, bloodworms, and various small live baits. Effective lures include 1-2 inch soft plastics like twister tails, small Fin-S plastics, Bass Assassins, and tiny swim shads in white, yellow, chartreuse, and brown colors.

When is the best time to fish for White Perch in Indiana?

White Perch fishing in Indiana is most productive during late spring through fall, with prime action occurring from late March through October. They spawn when water temperatures reach 60-68°F in late spring, typically May-June, during which time fishing should be avoided to protect spawning activities.

How do you catch White Perch in Indiana?

Fish baits either under floats or with split shot on bottom. Work small lures with twitches near bottom. Three-jig rigs with Charlie Brewer-style jigs are highly effective for catching multiple fish.

What do White Perch eat?

White Perch are opportunistic predators that heavily consume fish eggs - particularly walleye, white bass, and their own species' eggs, often making up 100% of their diet during spring spawning periods. They also feed on zooplankton, small fish, aquatic insects, crustaceans, and minnows.

Where do White Perch live in Indiana?

In Indiana waters, they prefer shallow areas (6-12 feet deep) with little cover and muddy/silty substrates, though they can be found as deep as 360 feet in some waters. Outside of spawning, they school heavily and move between deep winter refugia and shallow feeding areas.
