James A. Gabel 1974 Large trap nets were evaluated as a commercial gear for capturing buffalo fish during July-September 1965. During the 72-day fishing period, 13,171 fish weighing 21,669 kg were taken. Bigmouth buffalo (<i>Ictiobus cyprinellus</i>) and smallmouth buffalo (<i>Ictiobus bubalus</i>) dominated the catch (78.2% by weight). Eight sport species accounted for 3.6% of the total catch. Both 7.0-cm and 12.7-cm mesh (extended measure) were used in the back of the bailing crib of the nets to determine the effect of the 12.7-cm mesh in reducing the catch of sport species and nonmarketable size groups of commercial species. The 12.7-cm mesh reduced the catch of nonmarketable bigmouth buffalo 29%, smallmouth buffalo 11%, river carpsucker (<i>Carpiodes carpio</i>) 18%, carp (<i>Cyprinus carpio</i>) 8%, freshwater drum (<i>Aplodinotus grunniens</i>) 35%, and sport species 68%. application/pdf en U.S. Fish and Wildlife Service An experimental trap net fishery, Lake Oahe, South Dakota, 1965 reports
