NOTES ON THE RUN OF SUCKERS AND BUFFALO-FISH. 



From the information stated below and from the many other reports 

 given by old residents of southern Minnesota it is evident that at one 

 time large buffalo-fish and suckers literally filled many of the lakes in 

 this portion of the State, and were especially noticeable during the 

 spawning season. -Inst what has become of these fishes is still a quea 

 tion, for they do not seem to be present in any of these lakes now where 

 they were once so abundant, or. if so. only in limited numbers, ['rob- 

 ably many of them have been killed by freezing, since the water in all 

 the lakes is now so much more shallow than it was formerly. This [a 

 certain in some of the lakes, for the fish have been found along the 

 shores in the spring in immense numbers dead, but it is not true of all 

 the lakes. It is not certain just what species of buffalo is referred l> 

 in these reports, for none have been examined since the writer b 

 to collect information concerning them. A dead one found on the 

 shore of Big Stone Lake in 1892 was identified as Tctiobus cyprinella, and 

 it is thought that possibly this is the species referred to in the other 

 lakes of the region. 



Buffaloes were reported to be very common in big Stone bake in 

 1892 and were often taken in Large numbers during the spawning 

 season, which is the latter pari of May or the lirst of June, or. as the old 

 settlers put it, "when the plum blossoms are out." Both the buffa- 

 loes and the suckers (Catostomm commersonii are seen bu1 a shorttime, 

 generally for only a day or two. but at that time every fish seems to 

 have come to the shore, and each scrambles to see how near he can gel
