The commercial fishery in Lake Oahe, North and South Dakota, 1964-70

Ten species were commercially harvested in Lake Oahe, among which bigmouth buffalo (Ictiobus cyprinellus) predominated (63.8% of the total weight), smallmouth buffalo (Ictiobus bubalus) and goldeye (Hiodon alosoides) ranked second, and third. Variations in the seasonal and annual production of buffalo were governed by market conditions and availability. Production of minor species depended on the amount of fishing effort directed toward the harvest of buffalo. Gill and hoop nets were the principal fishing gears. The fishing season usually extended from April through December; most fishing was in May through August.

An experimental trap net fishery, Lake Oahe, South Dakota, 1965

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 ( Ictiobus cyprinellus ) and smallmouth buffalo ( Ictiobus bubalus ) 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 ( Carpiodes carpio ) 18%, carp ( Cyprinus carpio ) 8%, freshwater drum ( Aplodinotus grunniens ) 35%, and sport species 68%.
