black bass, walleye and white bass, with smaller numbers of 
most of the minor game fishes of the region. Considering 
the comparatively limited area of water, the catch is very 
heavy, yet the supply keeps up remarkably well. It is evi¬ 
dent that for these fishing grounds the spawning grounds of 
Lake Pepin are a constant source of supply, a source that will 
always remain inexhaustible, except conditions be changed 
very materially in the future. 
36. Stizostedion vitreum. Walleye. A fairly common 
form here, often of good size. Like all the other game fishes 
of the lake, it does not readily take the hook here. Several 
miles below, in the Mississippi, it is caught in great numbers. 
37. Stizostedion canadense griseum. Sand Pike. A com¬ 
mon fish, and one of the few that is readily hooked. It is of 
rare occurrence in the nets. 
38. Perea flavescens. Perch. The yellow perch is a rare 
fish in Lake Pepin. Only a fev were caught in our small 
seines, and much fishing with hook and line failed to produce 
any. 
39. Percina caprodes. Log Perch. The log perch is the 
most numerous of shallow water fishes in Lake Pepin. Most 
of the specimens are 8 centimeters or less in length; a few of 
15 to 16 centimeters were taken. The specimens are all some¬ 
what intermediate between typical caprodes and the variety 
zebra of Agassiz. They all have a naked nape, but the fins 
barred as in the typical form. Depth five and one-half in 
length. 
JfO. Hadropterus guentiieri. Only five specimens occur in 
our collections. Outside of the log perch and Johnny darter, 
darters are uncommon in the lake. 
bl. Boleosoma nigrum. Of constant occurrence together 
with Percina, but not quite so numerous as the latter. 
Jf.%. lloccus chrysops. White Bass. A common form, 
almost daily seen in our seines, although always in very small 
numbers. Many young specimens were caught along shore 
with the minnow seine. Of all the game fishes of Lake Pepin, 
this one most readily takes the hook.
