Thiamine (Vitamin B1) Deficiency in Fish and Wildlife

In the last few decades, thiamine deficiency has been observed in fish and wildlife in the Great Lakes, Alaska, Sweden and several other areas in North America and Europe. Thiamine is an essential vitamin needed for cell function. Thiamine deficiency has been linked to neurological disorders, immunosuppression, and lower reproductive viability. These disorders potentially reduce populations of...

Pallid Sturgeon Early Life

CERC biologists focus on improving understanding of biomechanics of eggs, free embryos, and larvae through direct observation and measurement. An improved understanding of biomechanics – how biotic conditions and processes interact with physical processes to result in changes in survival – is necessary to create quantitative links between management actions and population-level results.

Development and Evaluation of Novel Capture Gears for Bigheaded Carps

Mass removal of Silver Carp Hypophthalmichthys molitrix and Bighead Carp Hypophthalmichthys nobilis, hereafter referred to as bigheaded carps, is a primary management action to contain the population growth and reduce upstream dispersal. The use of passive trap nets to harvest bigheaded carps may effectively supplement active capture techniques. The USGS is working with...

Use and Evaluation of Stimuli for Herding Bigheaded Carps to Increase their Capture Efficiency

Mass removal of silver carp Hypophthalmichthys molitrix and bighead carp Hypophthalmichthys nobilis, hereafter referred to as bigheaded carps, is a primary management action to contain the population growth and reduce upstream dispersal. Given their evasive behavior and gear avoidance, catching bigheaded carps efficiently has been difficult. Techniques that can allow managers...

Chemical Attractant Investigations to Increase Aggregation and Harvest for the Control of Asian Carp

Silver Carp Hypophthalmichthys molitrix and Bighead Carp Hypophthalmichthys nobilis, hereafter referred to as bigheaded carps, are rapidly expanding their range. Federal agencies and the Illinois Department of Natural Resources are focused on keeping invasive carps out of the Great Lakes. The development of an effective attractant may assist managers with capturing carps in...

Assessment of Acoustic Stimuli for Manipulating Movement of Bigheaded Carps

Invasive Silver Carp Hypophthalmichthys molitrix and Bighead Carp Hypophthalmichthys nobilis, hereafter referred to as bigheaded carps, have displayed a negative phonotactic response when presented with a broadband acoustic stimulus. Additional study is needed to identify effective acoustic stimuli for manipulating bigheaded carp behavior, and to test bigheaded carp responses to those stimuli...

Synthesis of Hydrologic and Geomorphic Drivers of Riverine Habitat Dynamics

Habitats of many rivers of the US are perceived to be degraded as a result of human-induced stresses.  CERC scientist are focusing physical habitat as measured by depth, velocity, and substrate, in order to establish relevance of physical habitat to biota.

Geomorphic Trends and Dynamics, Missouri National Recreational River

The two mainstem Missouri River segments of the Missouri National Recreational River (MNRR) represent some of the least altered channel form and most complex physical habitat on the Missouri River. The 39-mile segment is located in an inter-reservoir reach between Fort Randall Dam and Lewis and Clark Lake and the 59-mile segment is located below Gavins Point Dam, the downstream-most water...

Ozarks Stream Dynamics and Native Mussel Habitats

The National Park Service is implementing plans for the survey and management of the mussel fauna at the Ozark National Scenic Riverways and Buffalo National River in Missouri. CERC scientists are conducting research to understand how geomorphic patterns effect the distribution of mussels in Missouri streams.

Validation of Zinc and Nickel Biotic Ligand Models Based on Toxicity Testing in Natural Waters with Ceriodaphina dubia

Most states use outdated hardness-based criteria to regulate metals in surface waters. The slow adoption of new criteria based on biotic ligand models (BLMs) reflects uncertainty about whether these models can reliably predict toxic effects of metals on aquatic biota across the wide range of water quality conditions affecting bioavailability.

An Evaluation the Chronic Toxicity of Metals in Water and Sediment to the Unionid Mussel, Fatmucket (Lampsilis siliquoidea), in Exposures Representing Conditions in the Tri-States Mining District

The Tri-State Mining District (TSMD) is a large (about 500 sq. mi.) historical lead and zinc mining area that includes portions of Kansas, Missouri and Oklahoma. The TSMD yielded about 460 million tons of ore between 1885 and 1970, resulting in contamination of surface water, groundwater, sediments, and soils in the Spring River and Neosho River basins by lead, zinc, and other heavy metals....
