790 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



Amhloplites rupestris, (Raf.,) Gill ; rock bass. — Rare ; taken with the 

 preceding-; sometimes caught with hook from the piers. 



Lepomis palUdus and Eupomotis aureus ; sunfish. — Taken in small num- 

 bers throughout the season. 



Perca americana, Schrank; yellow perch. — Common throughout the sea- 

 son, averaging 20 pounds daily. Taken in varying numbers from the 

 piers all summer. The fishermen say they do not follow the leader well, 

 so are not taken in large quantities as they would otherwise be. 



Stizostefhium vitreum, Cuv. and Val.; wall-eyed pike. — (^-ommon. A 

 few taken daily until the 1st of July. 



Eoccus chrysops, (Kaf.) Gill.; white bass. — The first taken the first of 

 July, after which it became quite common, but no large quantities were 

 taken. The quantity varied from 10 to 50 pounds daily during July. 



Usox lucius, Lin.; lake pike. — Very rare in the pounds south of the 

 pier. One specimen was taken in net 3, pound B, just before the nets 

 were removed in July. In net No. 2, just north of this, they were 

 abundant, quite a number being taken daily. The only reason for this 

 is that they must have all been moving south parallel to the shore, and 

 so been stopped by the first leader. If this was the case they must 

 swim in a limited path, for none were taken in net No. 1, which was a 

 little iarther in shore and situated north of this net. 



Umbra limi, (Kirt) Giinth.; mud-minnow. — In the fall and spriug this 

 species frequents the vicinity of the piers in large schools, and quanti- 

 ties are caught in dip nets to use for bait on the set lines. During the 

 summer they are very rarely seen near shore. The day succeeding 

 severe storms in the summer they congregate in a dense mass inside the 

 pound, and as it was slowly lifted would follow it to the surface. At 

 the first splash they dart through the meshes of the net, and disappear 

 as though by magic. 



Coregonus albus, Les.; white-fish. — This species commences running the 

 first of May, and the season is at its height the last of this month. From 

 the first week in June they gradually decrease in numbers until the 

 middle of July, when only a few stragglers are taken. The largest quan- 

 tity taken at this end of the lake last season, and from one net, was ob- 

 tained the first week in June, from net No. 3, and amounted to over 

 three hundred pounds in one day. Hard storms, which cause the water 

 near shore to become muddy or full of sand, drive this species into 

 deeper water; but as soon as the water clears they return. When 

 driven into deep water by a storm the first of July they do not return, 

 and the fishermen say it is useless to leave the nets ont after a storm at 

 this time of year. 



Argyrosomus clupeiformis, Mitch.; lake herring. — This species com- 

 menced running shortly after the white-fish began, and continued to run 

 with the white-fish until the close of the season. The first of June, when 

 the may-flies [Ephemerw) swarm along the lake shore, the herrings come 

 in close to the pier for the purpose of eating the insects which fall into the
