Summary
Using juvenile individuals of 3 species of carp (Family: Cyprinidae), we tested the potential for six amino acids to elicit an extracellular electro-olfactory response within the naris using gelatin-based electrodes. The amino acids L-alanine, L-arginine, L-aspartic acid, L-asparagine, L-glutamine, and L‑glutamic acid were tested on Grass Carp (Ctenopharyngodon idella), Bighead Carp (Hypophthalmichthys nobilis), and Silver Carp (H. molitrix) to provide a comparison among amino acids both within and among species. Each row in the data set represents exposure to a single amino acid. Each individual fish was exposed to up to four amino acids sequentially in a random order, representing a trial; each individual was a subject for exactly [...]
Summary
Using juvenile individuals of 3 species of carp (Family: Cyprinidae), we tested the potential for six amino acids to elicit an extracellular electro-olfactory response within the naris using gelatin-based electrodes. The amino acids L-alanine, L-arginine, L-aspartic acid, L-asparagine, L-glutamine, and L‑glutamic acid were tested on Grass Carp (Ctenopharyngodon idella), Bighead Carp (Hypophthalmichthys nobilis), and Silver Carp (H. molitrix) to provide a comparison among amino acids both within and among species. Each row in the data set represents exposure to a single amino acid. Each individual fish was exposed to up to four amino acids sequentially in a random order, representing a trial; each individual was a subject for exactly one trial. The response metric was the measured response peak, in millivolts, corrected by subtracting the mean baseline during exposure to well water 60 seconds prior to the amino acid response. The baseline-corrected, absolute value of the response to ultrapure, deionized (UDI or “Nanopure”) water immediately preceding a trial is also included. Other relevant factors that could influence measured individual response, such as number of times electrodes were repositioned within a trial (n = 4 repositions across 76 trials), nominal concentration of amino acid solutions, fish mass, holding tank temperature, and flow rate of water and amino acid solutions over the naris are included. Identifying data, namely date of trial and an individual subject ID (equivalent to a trial ID), are also included.
In support of management efforts to control and eradicate Grass Carp, Bighead Carp, and Silver Carp from U.S. waterways, a variety of research has been done on feed additives and compounds such as food cues (e.g, amino acids), pheromones, and alarm-eliciting compounds that could be used to attract invasive carp as a means for aggregating them for easier harvest. These data were collected in order to establish the electro-olfactory response of these species to amino acids of interest and to inform the design of behavioral trials to understand the potential for these amino acids to serve as attractants or deterrents for the carp species of interest.
