CALICO BASS. 



found that their size compared favorabl}- with that which they 

 attain in Europe. 



It has been shown at government fish cultural stations and else- 

 where that a few adult carp placed in waters overstocked with 

 bass do not increase in number, their young being wholly con- 

 sumed each season. It is well to introduce only a limited number 

 of carp, since too many of them, owing to their rooting habits, 

 will not only destroy the water plants, but also make the water 

 too roily. It has been found that the introduction of carp for 

 feeding fishes, is also favorable in ponds containing crappie, the 

 slight roiling of the water, which they cause, being beneficial to 

 the latter rather than otherwise. It should not however be intro- 

 duced into overstocked bass w-aters as a food supply until yellow 

 perch or other species have been tried. 



All ponds, whether natural or artificial, containing food-fishes 

 should be stocked with brook-minnows, shiners, chubs, fresh- 

 water killifish and other small species to constitute a food supply. 

 The killifish and other small species, it may be noticed in passing.
