With the Spotted bass having a shorter length limit on Lake of the Ozarks, Truman and Stockton I thought a fish id refresher might help those unsure of the difference.
Many anglers who catch a spotted bass believe they have caught a largemouth bass, undoubtedly because the coloration is similar, both having a greenish hue and a broad stripe of diamonds or blotches along the midline of the body. The spotted bass, like all black basses except the largemouth, has scales on the base portion of the second dorsal fin, its first and second dorsal fin are clearly connected, and its upper jaw bone does not extend back to or beyond the rear edge of the eyes. The spotted bass is also often confused with the smallmouth bass, but lacks the vertical bars that are present on the sides of the body in the smallmouth. The spotted bass also has all black spots below the lateral line (the rear edges of certain scales are black) unlike either the largemouth or the smallmouth. Juveniles of the species resemble the young of smallmouth bass in having a broad band of orange at the base of the tail, followed by a broad black band and white edge.
I found this on the MDC website;
Large, elongated fish with a large mouth. Upper jaw reaches to or slightly beyond the rear margin of the eye in adults. Green with dark horizontal stripe. Upper parts are greenish with darker mottlings; the lower sides and belly are whitish with dark spots arranged in streaks. The midside has a broad, dark continuous stripe. Cheek scales much smaller than rest of body scales. Tongue has rough patch.
Total length: 10 to 17 inches; weight: 1/2 to 3 1/2 pounds; maximum about 20 inches and 4 to 5 pounds.
