Profiles of digestive enzymes of two competing planktivores, silver carp and gizzard shad, differ Profiles of digestive enzymes of two competing planktivores, silver carp and gizzard shad, differ
Typically, studies in digestive physiology in fish focus on a few enzymes and provide insight into the specific processes of the enzyme in a targeted species. Comparative studies assessing a wide number of digestive enzymes on fishes that compete for food resources are lacking, especially in the context of an introduced species. It is generally thought that the invasive silver carp (SVC

Ethanol and sodium acetate as a preservation method to delay degradation of environmental DNA Ethanol and sodium acetate as a preservation method to delay degradation of environmental DNA
Environmental DNA (eDNA) samples that are collected from remote locations depend on rapid stabilization of the DNA. The degradation of eDNA in water samples is minimized when samples are stored at ≤ 4 °C. Developing a preservation technique to maintain eDNA integrity at room temperature would allow a wider range of locations to be sampled. We evaluated an ethanol and sodium acetate...

Assessment of carbon dioxide piscicide treatments Assessment of carbon dioxide piscicide treatments
Few chemicals are approved to control or eradicate nuisance fish populations in the United States. Carbon dioxide (CO2) is currently being developed and studied as a new piscicide option for nonselective population control. This study evaluated dry ice (solid state CO2) as a simple CO2 delivery method during winter piscicide applications. Nonnative Silver Carp Hypophthalmichthys molitrix...

Using dissolved carbon dioxide to alter the behavior of invasive round goby Using dissolved carbon dioxide to alter the behavior of invasive round goby
Fisheries managers need effective methods to limit the spread of invasive round goby Neogobius melanostomus in North America. Elevating carbon dioxide (CO2) in water at pinch points of rivers (e.g., inside locks) is one approach showing potential to deter the passage of invasive fishes, such as bigheaded carps Hypophthalmichthys spp., but the effectiveness of this method to alter round...

Comparing efficiency of American Fisheries Society standard snorkeling techniques to environmental DNA sampling techniques Comparing efficiency of American Fisheries Society standard snorkeling techniques to environmental DNA sampling techniques
Analysis of environmental DNA (eDNA) is an emerging technique used to detect aquatic species through water sampling and the extraction of biological material for amplification. Our study compared the efficacy of eDNA methodology to American Fisheries Society (AFS) standard snorkeling surveys with regard to detecting the presence of rare fish species. Knowing which method is more...

Seasonal trends in eDNA detection and occupancy of bigheaded carps Seasonal trends in eDNA detection and occupancy of bigheaded carps
Bigheaded carps, which include silver and bighead carp, are threatening to invade the Great Lakes. These species vary seasonally in distribution and abundance due to environmental conditions such as precipitation and temperature. Monitoring this seasonal movement is important for management to control the population size and spread of the species. We examined if environmental DNA (eDNA)...
