Fish conservation using cost-effective technologies

ATET-Tech is an environmental consulting company focused on fish conservation at industrial water intakes including once-though-cooling, hydroelectric, irrigation, pulp & paper, and manufacturing.  ATET-Tech has experience evaluating different fish protection systems such as barrier nets, acoustic and light systems, fine mesh screens, fish pumps and fish return systems especially related to cost-effectiveness, biofouling, and strengths/weaknesses in mitigation control. ATET has also developed a new underwater LED device (Light Guidance Device, LGD) for fish management applications which has been designed to work alone or integrated with different fish conservation methods.
