Description.—The white perch closely resembles its larger relative, the striped bass, in its general form, especially in the deep keelless caudal peduncle and in the number, outline, and arrangement of its fins. It is a deeper fish, however (only about two and two-thirds times as long as deep, not counting the caudal), and more compressed, almost as thin, in fact,

Description.—The white perch closely resembles its larger relative, the striped bass, in its general form, especially in the deep keelless caudal peduncle and in the number, outline, and arrangement of its fins. It is a deeper fish, however (only about two and two-thirds times as long as deep, not counting the caudal), and more compressed, almost as thin, in fact, as a butterfish (p. 245). The dorsal profile of its body is more convex than is that of a bass but that of its head is concave and its mouth is smaller. Furthermore, the two dorsal fins of the white perch are confluent while in the striped bass they are separated by an interspace; its anal rays are less. Fig. 121.—Egg Flo. 122.—Larva, 6 days old, S millimeters WHITE PERCH (Morone americana) numerous, the anal spines are much stouter than those of the bass and the second and third are about equal in length (graduated in the bass), and there is only one sharp spine and a blunt angle at the margin of the gill cover of the perch, while there are two spines in the bass. Finally, there is a constant difference in color. The first dorsal (9 spines) is rounded in outline with its third and fourth spines longest, and although there is no free space between the two dorsal fins they are entirely separated by a deep notch. The second dorsal fin (1 spine and 12 rays) is rhomboid in outline and so short that it leaves bare a long caudal peduncle. The anal fin (9 to 10 rays preceded by 3 stout spines) originates under the middle of the.
