Improving molecular techniques for monitoring Asian carps: Characterizing eDNA associated with spawning, eDNA persistence, and validation of new marker technology Description of Work This spring (2014) we will measure Asian carp eDNA over time at a Missouri River site downstream of multiple spawning areas before and during spawning. We will measure the amount of Asian carp eDNA in water samples. The amount of eDNA will be related to the numbers of eggs and larvae counted in matched samples (water samples taken at the same time and place). The time since the eDNA was released by the carp will be estimated and these results will be related to the average age of AC eggs and larvae in matched samples. We will also test for substances which interfere with the eDNA measurement techniques and can lead to false negatives. We will also be validating markers developed by USGS and...

Template 66, Template 673, Fewer tags Water hardness effects on hatching success of Asian carp eggs Description of Work In separate studies, bighead carp and silver carp were raised in waters of varying hardness. Survival, correct development, and hatching success were monitored. Additionally, a search of the Asian literature (including Chinese-language literature) on water hardness in areas where Asian carp are native was performed. Relevance & Impact If soft water limits Asian carp hatching success, then this would mean that large areas of the Great Lakes and east and west coast drainages would not be at risk of Asian carp establishment. Key Findings Both bighead carp and silver carp developed normally and the eggs hatched normally in all water hardnesses tested, including very soft water. The Yangtze River,...

Template 66, Fewer tags Field Evaluation of chemical attractants to control Asian carp and development of protocols for field verification of response Description of Work Initial tests of a variety of chemical stimuli identified a strong response to the algal food attractant. Field testing of chemical stimulants based on algae will seek to identify potent mixtures based on persistence and duration of attraction. These studies will include consideration of component chemicals such as amino acids produced by algae that enhance the attractiveness of the stimulus, based on carp smell and taste senses. Means of providing a sustained release of the stimulant will be explored through tests of various media. Tests will be conducted to confirm the possibility that carp can be conditioned to feeding stations that can be used to facilitate their capture. Relevance & Impact...

Template 673, Fewer tags Cooperative Science and Monitoring Initiative (CSMI) - LAKE HURON Description of Work USGS will conduct seasonal sampling of benthic invertebrates, zooplankton, prey fish, and their diets to complement the seasonal lower trophic level sampling by EPA. A point of emphasis is describing the vertical distribution of planktivores and their zooplankton prey, to fill a knowledge gap on these predator/prey interactions. These data will provide a more holistic understanding of how invasive-driven, food-web changes could be altering energy available to sport fishes in the Great Lakes and used to build bioenergetics models that can evaluate whether zooplankton dynamics are being driven by limited resources or excessive predation. Understanding the key drivers of zooplankton will provide...

USGS will coordinate the communication approach across multiple projects to most efficiently demonstrate technologies and get the information to the stakeholders and managers. A demonstration of Asian carp control technologies occurred in August 2013 near Morris, Illinois at a backwater pond of the Illinois River. State and federal partners were invited to visit an application of the Integrated Pest Management approach to Asian carp control. Water guns, algal feeding attractant, acoustic fish tracking, and commercial fishing were implemented in a coordinated manner to reduce...

Template 66, Template 673, Fewer tags Behavior of Asian carp larvae Description of Work Bighead, silver and grass carp larvae were raised in the laboratory. Larvae were observed during the hatching process. Recently hatched larvae were placed in 10 feet tall clear vertical containers where the carp were exposed to light for a similar amount of time during the day as they would experience in a river during the spawning period. Depth selection, swimming behavior, and swimming speed were observed in both day and night periods. Relevance & Impact Understanding the stage at which Asian carps begin swimming is critical to development of models that predict whether a river is adequate for reproduction by Asian carps. Knowledge of where and how Asian carp larvae arrive in nursery areas...

Template 66, Template 673, Fewer tags Evaluating the Safety and Efficacy of Pseudomonas fluorescens Strain CL145A to Control Dreissenid Mussels There is an immediate need for effective and safe tools to prevent the spread of planktonic larval dreissenids (quagga Dreissena rostriformis bugensis and zebra mussels D. polymorpha) and to rehabilitate and protect native unionid habitats by controlling existing dreissenid mussel populations in and around the Great Lakes. More than half of the 78 native unionid species in Minnesota, Wisconsin, Iowa, Missouri, Illinois, Indiana, and Ohio are listed as endangered, threatened, or of special concern. Although the US Fish and Wildlife Service (USFWS) considers zebra mussels to be an immediate threat to freshwater unionids in the Upper Mississippi River System, there is no effective tool to control established zebra...

Template 382, Fewer tags Developmental rate of embryos and larvae of bighead, silver, and grass carps Description of Work USGS employees worked with Chinese scientists to acquire and translate existing Chinese science on development. Then, bighead and silver carps were spawned and the eggs and larvae reared in the laboratory, with close control on temperature and very close observation of the different developmental stages. Multiple spawning events of each species were necessary to understand variability in developmental rate. Preserved voucher specimens and microscope photography were taken of all developmental stages. Relevance & Impact These data were first used to model the spawning locations of Asian carps in the Missouri River. They were later used in the development of the more advanced FluEgg model, which...

The trends found in the toxicant database were linked to physiochemical properties of the individual toxicants. Combining the toxicant trends with the physiochemical properties may allow for the prediction of toxicity and the identification of chemicals with selectivity for the Asian carp. Identifying a selective toxicant may provide control of Asian carps while minimizing effects on other non-target aquatic species. When Asian carp specific toxicants are identified from the initial screen within the database these toxicants are then further screened in toxicity assays...

Template 66, Template 673, Fewer tags Assessing life history traits of Asian carp in established and emerging populations to identify and characterize vulnerabilities that can be exploited for control Description of Work To achieve a better understanding of seasonal habitats and migratory behaviors of Asian carp, we will conduct studies using telemetry, sonar and conventional fish sampling to determine 1) if, when, and where Asian carp congregate, 2) habitat overlap between Asian carp and native fishes, especially native filter-feeding fishes and potential predators, and 3) the suitability of large rivers and tributaries for spawning by Asian carp. We will also assess feeding behaviors by sampling food particles from areas with telemetry-tagged fish, at random sites and in Asian carp stomachs. Food from these sources will be characterized with a particle analyzer, genetics and microscopy to determine preferences...

Template 66, Template 673, Fewer tags Great Lakes Tributary Assessment for Asian carp Habitat Suitability and Development of a Tributary Assessment Tool Description of Work USGS researchers have determined the densities of the eggs as these develop, and how much time the bighead and silver carp require to begin swimming and migrating laterally from flowing water into nursery habitat. This information about egg transport requirements was used to create a Tributary Assessment Tool also referred to as the Fluvial Egg Drift Simulator (FluEgg) model. The development of this tool was a collaborative effort between USGS and the University of Illinois. The tool takes into account the hydraulics of a river (water velocity and dispersion rates) and the water temperature (affects egg and larvae development rates) in order to determine if a river is sufficiently long and the...
