Quantifying the Cost of Replacing Recreational and Subsistence Fisheries Caused by Climate Change

Recreational fishing is very popular in the US and Canada and provides a substantial economic benefit. Subsistence fisheries is also important to the livelihoods and culture of Native Americanans and First Nations. However, there is concern that as fish communities may change in the future due to climate.climate.  Our objective will use existing data to determine how recreational fisheries cost ...

Evaluation of the bonus fishery created by the low-density stocking of Striped Bass in Bull Shoals Lake

Creating Striped Bass fisheries in reservoirs throughout the United States produces popular fishing opportunities for local anglers, non-local fisherman, and often supports businesses offering guided fishing services. As the Striped Bass fishery develops in Bull Shoals Lake, it is likely that its popularity will increase and angler expectations will resemble those of the adjacent Norfork Lake fishery. In the past there ..

Habitat Selection and Dispersal of Lake Sturgeon in Missouri River Tributaries


Lake Sturgeon have been listed as endangered in Missouri since 1974, and recovery efforts have been underway since the 1980s and have included primarily stocking fingerling fish in the mainstem big rivers and tributaries. However, there is a critical need to evaluate these management actions to guide future restoration efforts, particularly understanding the spawning requirements, dispersal, and movement .....


Potential for conservation lands in Middle Mississippi River floodplains to mitigate flood flows for ecosystem services

We will use 1- and 2-dimensional, spatially nested hydrodynamic models to explore the hydrologic and hydraulic potential for improving ecologic diversity and potential of National Wildlife Refuge lands in the Middle Mississippi River (MMR). The first phase of the project is a landscape-scale approach that will use existing 1-d hydrodynamic models to develop indices ...

Habitat Use and Distribution of Lithophilic Spawning and
Riffle Fishes in the East Fork Black River

In July 2014, the Federal Energy Regulatory Commission (FERC) issued a new license for Ameren Missouri (Ameren) to continue operation and maintenance of its Taum Sauk Pumped Storage Project.  Part of this requirement was to determine the use of coarse gravel from the reservoir’s sediment control sediment trap, particularly to enhance native fish spawning in downstream reaches were the river may be gravel starved...

Identifying electrofishing capture-prone response thresholds for catfish and smallmouth bass in Missouri

Standardization of electrofishing output will minimize bias, reduce variation in catch, and allow for more valid spatial and temporal comparisons of sample data, regardless of the electrofishing control box used. Biologists need to know how conductivity of the water relates to the effective conductivity of Smallmouth Bass, Blue Catfish and Flathead Catfish ...


Development of Sampling Protocols and Application to Missouri's Mid-Sized Rivers

Substantial monitoring and research has and is currently conducted on mainstem big rivers such as the Missouri and Mississippi and on smaller, wadeable streams but little information exists for the mid-sized rivers in Missouri (e.g., tributaries of the Missouri and Mississippi Rivers and other non wadeable rivers). However, these rivers ....

Identifying Relevant Recent Advances in Ecological Flow Linkages

Stream flow is a critical, yet complex driver of ecological processes in streams.  Numerous studies have attempted to identify metrics that best represent hydrologic alteration caused by dams, diversions, withdrawals, land use, and other anthropogenic activities.  However, there is no consensus on how these hydrologic indices are linked to ecological processes and fishes.  The science related to ecological flows is rapidly evolving and many studies....

Linking Habitat Features to Fish Movement and Dissolved Oxygen and River Flow in the Lower Osage River

Numerous flow management decisions are being made on rivers throughout the world and these decisions are increasingly incorporating consideration of the physical habitat needs of fish and other aquatic life. However, long term monitoring studies to detect response of fish species to new flow regimes are few, and there is little information to substantiate ecological response to flow alteration, and empirical models ....


Science to Inform Management of Floodplain Conservation Lands under Non-Stationary Conditions

The objective of this project is to formalize understanding of science information needs for management of conservation lands on large-river floodplains under non-stationary climatic and land-use conditions. The work is necessary to establish a firm foundation for development of cost-effective, relevant floodplain science to inform management. The work is expressly focused on understanding and addressing managers’ information needs in dynamic...
