U. S. BUREAU OF FISHERIES 



From the above table it may be seen that the buffalofish and 

 paddlefish are the only species of which the total catch is being main- 

 tained, as compared to former years. Carp, catfish, and drum are 

 being taken in considerably lesser amounts than formerly, though 

 still approaching their former importance. The commercial catch of 

 all other species has declined in no uncertain fashion. 



The appearance of quillback in the statistics of 1922 for the first 

 time does not necessarily indicate the beginning of a new fishery for 

 this species. It may have been reported previously under a different 

 name, most probably among the suckers. 



FISHERIES OF LAKE PEPIN AND LAKE KEOKUK 



In view of the rather extensive biological and ecological experiments 

 and investigations to which the aquatic life of Lake Pepin and Lake 

 Keokuk has been subjected in recent years, especial significance is 

 attached to the statistics of the fisheries of these lakes. There are 

 presented herewith the detailed statistics for the year 1922 and com- 

 parative statistics for the years 1914, 1917, and 1922.
