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 …

Early fisheries investigation of the Missouri River fish community indicated that Sauger were common throughout Nebraska, including all major Missouri River tributaries. However due to many factors, their current range is restricted to the Missouri River and the lower reaches of a few tributaries. Hesse (1994) recommended listing Sauger as a state endangered species but this recommendation was never implemented. Therefore, the objective of this paper is to reevaluate the current population status of Sauger in the Missouri River along Nebraska’s border. Over 2,100 Sauger have been captured from the Missouri River along Nebraska’s eastern border since 2003. Sauger were …

Many North American bats are active outside hibernacula in winter, but no information on winter activity has been reported for Nebraska. We recorded activity of bats during two winters (December-February 2012-2013 and 2013-2014) at one location in southeastern Nebraska with an acoustic detector. Bats were active throughout both winters and temperature at sunset was a good predictor of bat activity. Red bats (Lasiurus borealis) were active at our site in early December but were not recorded later in winter. We suspect these individuals were late migrants to more southern wintering sites. Big brown bats (Eptesicus fuscus) …

Since 1991, 19 specific black-footed ferret reintroduction projects have been conducted across 8 States, Canada, and Mexico. All five of the first ferret reintroductions (from 1991 to 1996) continue to be occupied by ferrets. The photographs of October 31 and November 1 are the first unequivocal documentation of black-footed ferrets on the Standing Rock Indian Reservation. Ferrets observed on Standing Rock may be dispersals from the nearby Cheyenne River Sioux Indian Reservation to the south. The nearest re-introduction site for ferrets is approximately 20 miles away, in Whitehorse, South Dakota, and the observation of ferrets on Standing Rock could document …

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 …

Anthropogenic alterations to the Missouri River have placed the Pallid Sturgeon (Scaphirhynchus albus) population in jeopardy and contributed to their listing as an endangered species. Pallid sturgeon were always less common than the sympatric Shovelnose Sturgeon (S. platorynchus); however, Pallid Sturgeon seemed to be more affected by river alterations as the river sturgeon ratio has become more skewed towards Shovelnose Sturgeon. Shortly after listing, population augmentation with hatchery produced Pallid Sturgeon began to supplement the diminishing wild population. Therefore, the objective of this study was to present the current population status of the Pallid Sturgeon in …

The Shovelnose Sturgeon Scaphirhynchus platorynchus remains the most abundant riverine sturgeon species in North American despite the anthropogenic modifications that have occurred throughout their historic range; however, their populations have declined throughout Nebraska since the construction of Fort Randall and Gavins Point Dams. Therefore, the objective of this study was to present the current status of Shovelnose Sturgeon in the Missouri River along Nebraska’s border. Data was acquired from 2003 to 2012 from all reaches of the Missouri River along Nebraska’s eastern border. Catch rates of Shovelnose Sturgeon increased in a downstream trend and were highest in the reach below …
