Notes for Tables of Electrof ishing Results 

 (Tables 5-29) 



1. Fish species are listed in phylogenetic order. All common and 

 scientific names are taken from A List of Common and Scientific 

 Names of Fishes from the United States and Canada , 3rd edition, 

 1970, American Fisheries Society Special Publication No. 6. 

 Species that were rarely taken by electrof ishing are not shown in 

 the Tables, but are discussed in the text. The values in the body 

 of each Table are determined by summing the number of fish or weight 

 of fish obtained at all stations in the navigation pool and dividing 

 the sum by the total number of half-hour intervals fished in that 

 pool. Thus the values are average catches per unit effort for each 

 pool. The number of electrof ishing stations in each pool are as 

 follows: Alton Pool (4-5), LaGrange Pool (6), Peoria Pool (8), 

 Starved Rock Pool (2), Marseilles Pool (3), and Dresden Pool (1). 



2. Values in the last two columns are the total number of fish or total 

 weight of fish taken during the designated year in the Illinois 

 River divided by the total number of half-hour intervals fished. 

 The Dresden Pool, Des Plaines River, is excluded from this tabula- 

 tion. 



3. An asterisk denotes that less than 0.01 fish were taken per 30 min- 

 utes fished. 



4. Zeros indicate that electrof ishing was conducted, but no fish of 

 the designated species were taken. 



5. Dashes indicate that no electrof ishing was conducted. 



6. NWT indicates that no weights were taken.
