Abstract
A system and method to induce fish anesthetizing or narcosis is described that induces a potential field across the body of a laboratory fish having a pair of electrodes, the waveform generated by this potential field is approximately balanced to reduce the introduction of anions into the solution, and a camera is mounted to observe the activity of the fish, so that the potential difference may be adjusted based on the state of the fish.
Claims10
A method for inducing an electrical potential across a laboratory fish, the method consisting of:
- creating an initial potential difference in a body of water across an anode and a cathode of a fish tank, said fish tank having the anode and the cathode spatially placed at the opposite ends of the fish tank;
- mapping a species to a voltage from a database of species electrical waveforms, wherein the database of species electrical waveforms is operably loaded into the programmable power supply;
- then increasing the potential difference between the anode and the cathode, such that there is a potential difference of up to 10V/cm across the body of the fish;
- then further decreasing the potential difference between the anode and the cathode to approximately 0V/cm across the body of the fish;
- so that when the potential difference first increases and then decreases across the body of the fish, the fish experiences a physiological change.
