by truck downstream to pool II, 2. The distance 

 between pools of 0.81 mile by water included 20 

 shallow riffles and 19 pools, 16 of the pools 

 especially suitable for bass. Two weeks later, 

 October 27, the home pool was censused. 



The simplicity of this single transfer makes it 



possible that, if this pool had been worked more 

 than the one time during the fall, a higher per- 

 centage of these bass might have been recovered. 

 Evidence substantiating this assumption was found 

 in recensusing this pool during August, September, 

 and October, 1951. In these three censuses 16

unnecessary to discuss the movement of individual 

 fish. When the home pool was examined 2 weeks 

 after the transfer, three of the seven bass were re- 

 captured, four were not, fig. 3. Even though less 

 than half of these fish were retaken after 2 weeks, 

 the experiment proves that bass can and will 

 return upstream to a home pool. It seems quite 



smallmouth bass were taken, of which 7 bore the 

 fin-clip mark of the home pool and were of sizes 

 corresponding to the seven tagged fish that had 

 been moved downstream in 1950. Although none 

 of these 7 bass bore tags when taken in 1951, 

 some of them may have been the fish tagged and 

 moved the previous year.
