Table 3. — Number and weight (in pounds) of each of the 10 most abundant species of minnows 

 collected, 1950, in each of the eight divisions of Jordan Creek, and the total number and total weight of 

 each species collected in all divisions combined. 



+ Less than 0.01 pound. 



common in the Salt Fork River, only one specimen 

 was collected in Jordan Creek. It was taken in 

 Division 3 after heavy fall rains. Forbes & 

 Richardson (1920) called this species Notropis 

 rubrifrons and recorded it as being present in 

 Illinois only in the Mississippi River drainage of 

 the northern third of the state. Thompson & Hunt 

 (1930) did not record it from Champaign County. 



Redfin Shiner. -- This minnow was rather scarce 

 in Jordan Creek collections, even though it is 

 generally abundant in the smaller, slow-flowing 

 streams of the Wabash River drainage in central 

 Illinois. 



Common Shiner. --The weight and number of 

 minnows of this species decreased progressively 

 upstream. Eighty-seven per cent of the weight 

 was taken in the wooded area. The greatest 

 numerical abundance was in Division 1 and was 

 associated with shade, rocky riffles, and short, 

 shallow pools. The larger individuals were found 

 in narrow but moderately deep riffles with 

 swift currents. 



Spotfin Shiner. — This species, Notropis spilop- 



terus , and a very similar species, N. whipplii, were 

 both present in the Salt Fork River, but only the 

 former was collected in Jordan Creek. It showed a
