Throughout the past century, the Missouri River has been highly modified which has negatively affected the native fish community. Previous research quantified the reduction of several native Cyprinidae species and made several recommendations to aid in recovery. However, these recommendations were not implemented. Therefore, the objective of this paper is to assess the current population trends of eight native cyprinid species and develop the current management objectives. Over 335,000 fish were collected from the Missouri River along Nebraska’s eastern border with mini-fyke nets and otter trawls from 2003 to 2012. Target Cyprinidae species consisted of less than five percent (n …

Lake Sturgeon (Acipenser fulvescens) occurrences in the Missouri River along Nebraska’s eastern border are historically sporadic and rare. Presently, the wild Lake Sturgeon population in this river reach may be extirpated. A Recovery Program initiated by the Missouri Department of Conservation (MDC) has stocked almost 150,000 hatchery-reared Lake Sturgeon into the lower Missouri River at several sites in Missouri. As a result, the number of Lake Sturgeon collected has increased. Since monitoring began in 2003, no Lake Sturgeon have been collected above Gavins Point Dam while 40 fish were collected downstream of Gavins Point Dam. The majority of …

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

As part of an effort across the western U.S. states led by the Western Governors’ Association, the Nebraska Game and Parks Commission synthesized information related to habitat for at-risk native species and natural plant communities. The result, submitted to the WGA in the fall of 2013, is coarse-scale, landscape-level information that can be used by anyone for land-use planning. The product of this west-wide collaboration is called the Crucial Habitat Assessment Tool (CHAT). The information, provided through an online GIS-mapping tool, is non-regulatory and gives project planners and the general public access to credible scientific data on a broad scale …
