Patent ID: 8739736

Claim:
A portable fish anesthetizing system comprising: a tank cover, an electrode pair, the electrode pair directly mechanically attached to the tank cover; a control system for creating a potential difference, the control system electrically connected to the electrode pair; a laboratory tank, the laboratory tank having a top rim, a bottom, and four upward walls connected to the bottom; a camera removably positioned on at least one of the upward walls, the camera connected to the control system; so that when the camera is connected to the control system, a series of fish images are recorded in the tank, the control system then identifies a class of fish, and in response to the class of fish detected, thereby adjusts a current flow; wherein activation of the current flow from the control system through the electrode pair creating a potential difference, occurs upon placement of the tank cover on the top rim of the laboratory tank, so that the fish experiences a physiological response; wherein the physiological response is at least one of electronarcosis, electrotaxis, and euthanasia.
