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.
