Robin D Calfee
Robin Calfee is a Research Biologist at the Columbia Environmental Research Center.
Since joining the USGS in 1991, Robin has devoted her career to investigating the impacts of contaminants to various aquatic organisms and developing methods for quantifying fish swimming behavior. Currently, her research focuses on testing the effectiveness of different control strategies for Asian Carp such as auditory stimuli, food attractants and supplemental capture techniques.
Science and Products
Development of a Ploidy Distinction Application: A Machine Learning Approach for Discriminating Triploid and Diploid Grass Carp (Ctenopharyngodon idella) in the Field
USGS scientists are researching a machine learning approach that can enable fisheries personnel in the field to determine the ploidy of wild-caught invasive carp.
Laboratory Investigations with Fish Species to Assist with Implementing Barataria-Terrebonne National Estuary Program’s Ecological Management Action Plans
WARC scientists will obtain live fish specimens from the field to conduct and enhance on-going laboratory research on harmful algal blooms and the use of piscicides to control invasive fish.
Use and Evaluation of Stimuli for Herding Bigheaded Carps to Increase their Capture Efficiency
Mass removal of the invasive silver carp Hypophthalmichthys molitrix and bighead carp Hypophthalmichthys nobilis (collectively referred to as bigheaded carp) is a primary management action in the United States to contain population growth and reduce upstream dispersal. Efficient capture and removal techniques are required to achieve this goal, and the USGS is working to develop and evaluate such...
Comparative Freshwater Fish Toxicity Testing of Antimycin A
Researchers are investigating the influence of Antimycin A on invasive carp and non-target fishes by measuring the effects of a novel species-specific bait formulation.
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 partner agencies to develop...
Chemical Attractant Investigations to Increase Aggregation and Harvest for the Control of Invasive 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 low-density areas such...
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 in...
