The fisli distributed in following lists were black bass, crappie, 

 white bass, war mouth bass, channel cat, wall eyed pike, ring' 

 perch and sunfish, all, or nearly all orders varying in size from 

 6 to 14 inches in length. We have used the larger fish for dis- 

 tribution for the reason that a careful investigation as to the 

 merits of the two methods, viz: Planting fry in large numbers 

 or adult fish in less numbers, has demonstrated the practica- 

 bility of the plant of the larger fish. In former reports we give 

 a number of instances when surprising results have been ob- 

 tained from such plants. 



A car load will contain from 1,500 to 3,500 fish, according 

 to size and variety used, and time of season plant is made. 



When distribution is made by a messenger with tanks in bag- 

 gage cars, not nearly so many large fish can be carried in same 

 tank space as aeration is produced by use of dipper, but when 

 cars are used, a continuous circulation of water through tanks 

 is had, water delivered in the shape of a spray. 



One hundred black bass of large size is sufficient to stock any 

 one locality, if the plant is properly protected and the increase 

 from them is great under proper conditions, as to food and 

 spawning beds. 



Commissioner McDonald of the U. S. Fish Commission reports 

 that 47 large black bass placed in a pond of the commission 

 near the Potomac river at Washington, D. C., in fall of 1891, 

 produced 48,000 young black bass in fall of 1892. Some had 

 attained a length of 6 inches, and in his opinion the old fish 

 and perhaps the larger of the fry had consumed many thou- 

 sands of the very small fry before the pond had been drawn 

 down to take the fish out for distribution. 



This was in a pond such as are used by the commission for 

 storing fish, and demonstrates in a practical way what is pos- 

 sible to obtain from such plants when all the favorable con- 

 ditions are supplied in running water.
