Gravel removal operations increase sedimentation, alter stream flows, elevate water temperatures and affect the permanent pools needed by small fish. Instream gravel removal during mid-May through July can disrupt Topeka shiner spawning activity. Sewage and soil erosion negatively affect water quality. Increased agricultural and urban development has elevated the amounts of sediment and nutrients in Missouri's streams. Some land use changes have altered water flow patterns contributing to the Topeka shiner's decline.
Private landowners own and manage most stream corridor habitat where the Topeka shiner lives.
Landowners are encouraged to take an active role to protect the water quality and habitat of this rare fish. The Department of Conservation and the U.S. Fish and Wildlife Service offer technical assistance and incentives to improve streams on private land. Private landowners can help by implementing the following suggestions. The Topeka shiner is an excellent indicator of water quality because of its sensitivity to habitat changes. Avoid constructing permanent impoundments in headwater areas inhabited by Topeka shiners.
