ATET opens a new branch as ATET-TECH US

We are glad to report that we have created  ATET-TECH US as we have recently incorporated in the state of Florida to conduct fish conservation business in the US for all water users. 

Latest Hydro Review article

An excellent summary of research activities of the LGD technology has recently been published in the June 2018 Hydro Review magazine (pg- 70-77). It includes results from a variety of species including  sturgeon and American eels.

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. Please contact us for copies of the publications. 

ATET-Tech scientists will be presenting at the Hydro Vision International this coming June in Charlotte, NC
