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.

Two new publications for LGD in 2018

ATET-TECH scientists co-authored two new publications with academic researchers highlighting test results for attraction and repulsion of fish using the proprietary LGD systems. One publication entitled Behavioural guidance of yellow-stage American eel Anguilla rostrata with a light-emitting diode (LED) device was published in the Endangered Species Reserach. A second publication entitled Preferences of age-0 white sturgeon for different colours and strobe rates of LED lights may inform behavioural guidance strategies was published at the Environmental Biology of Fishes.
