Morone americanus
Narrow mouthed bass, sea perch
The body color of the white perch shades from olive on the back to a silvery green on the sides with a whitish belly. The dorsal fin is not separated and the 2nd and 3rd anal spines are about the same size. There are no stripes on the sides.
White perch are predacious carnivores with juveniles feeding on aquatic insects, small crustaceans and small fish. White perch have been shown to prey on fish eggs of valuable sport fishes such as walleye, white bass and yellow perch when introduced outside their native range.
White perch entered the Mississippi River system through a canal connecting Lake Michigan with the Illinois River near Chicago. From there, white perch are expected to invade up and down the Mississippi River in coming years. White perch were introduced into Nebraska by the DNR to provide an additional sport fishery.
The fish frequent areas with level bottoms of compact silt, mud, sand or clay and show little preference for vegetation, structures or other shelter.
White perch are occasionally as much as 15 inches long and 2 pounds or a little more in weight. The average white perch is 8 to 10 inches long and 1 pound in weight, or less.
