Hoop nets and wing nets are estimated to have caught 46.7 per cent of the 

 1950 river catch. These devices were used on all the rivers fished commercially in 

 1950. The species and calculated poundages of fish caught in hoop nets are given in 

 table 12. 



More fish were taken with seines from the Illinois River thanfrom any of the 

 other rivers, table 13. On the Illinois and Mississippi rivers large hauls of carp and 

 buffalofishes often are made with seines fished under the ice during the winter months. 



In Illinois the use of the trammel net is restricted by law to the Mississippi 

 River and to the Illinois River below the Peoria dam. Carp and buffalofishes domina- 

 ted the 1950 catch taken with trammel nets from the Illinois and Mississippi rivers, 

 table 14. 



The basket trap is estimated to have taken 52.3 per cent of the Mississippi 

 River catch of catfish. While this fishing device was used primarily for catfish and 

 bullheads, other fishes were taken occasionally with it, table 15. 



Hooks were used commercially on trotlines and throw lines on most of the 

 rivers. Carp and catfish made up the greater part of the catch taken on this type of 

 gear, table 16.
