COMMON FISHES OF MISSISSIPPI RIVER 
219 
to migration are buffalo fishes, sauger, white bass, yellow bass, paddlefish, sturgeons, 
and Fulton catfish. 
15. If practicable a study ought to be made of the winter habits of fishes in the 
Mississippi and the possible hibernation of fishes in the deeper parts at that time. 
Such an investigation offers considerable difficulty, however, in view of the heavy 
ice sheet that forms comparatively early in northern waters. 
16. Strongly to be recommended is a study of the early life histories of fishes 
by the blanket method of towing and trawling for eggs and larval fishes and the patch- 
ing together of the fragments of information gained at one time or another in dif- 
ferent places. Such methods, applied in the sea, have been almost the chief reliance 
in gaining information regarding the fife histories of marine fishes. Perhaps it is 
only by methods of this kind that the breeding habits of the paddlefish, herring, Ohio 
shad, drum, etc., will be learned. 
17. Two suggestions regarding practical work may be repeated here. The 
occurrence of young eels at the base of the dam can be inquired into more particu- 
larly and consideration given to the possibility of trapping them in quantities and 
transplanting them to the waters above the dam, so that the upper river may be annu- 
ally stocked with young eels. The transplanting of some Fulton catfish from the 
river below into Lake Keokuk may be worth while in the possible event that they 
might survive the winters in the deeper waters of the lake and replenish the river for 
a short distance above the lake. As the lake is about at the former northern limit 
of range of the species, favorable results from the experiment need not be expected 
with assurance.
