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 Evaluation of an Integrated Pest Management approach to bighead and silver carp control Description of Work Hydroacoustic surveys were used to characterize the distribution of fish within the backwater before, during and after the addition of algal feeding attractants, establishment of a water gun barrier and commercial fishing activities. Algal feeding attractants were injected at predetermined locations in the backwater to attract and concentrate Asian carp in the closed portion of the backwater. Nine days after the first algal feeding attractant was added, a water gun barrier was established at the narrowest location on the backwater. The water gun barrier was established about 14 hours before commercial fishers began 3 consecutive days of carp removal; the water gun barrier operated continuously...
