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.
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. Please contact us for copies of the publications.
ATET-TECH was granted a US patent for its invention entitled: Integrated Fish Diversion System and Lighting Device Used Therein. A total of nine different claims were granted. and the effective date is February 27, 2018.
ATET-Tech scientists jointly with colleagues from LimnoTech and Carleton University will be presenting a paper at the Hydro Vision International Conference to be held in June 26-28 in Charlotte, NC. The paper's title is CFD Design of an integrated fish passage system using new light guidance technologies.
ATET-Tech jointly with DFO and Carleton University scientists presented a paper entitled: Behavioural Guidance of Yellow-Stage Americn Eel with a Light-Emitting Diode (LED) Device at this symposium held with EPRI sponsorship this past December 12-13, 2017 in Cornwall, Ontario
