Fixed-location horizontally-directed echosounder was used in a deep stratifying eutrophic lake to study fish behavioural reaction in response to counterfeit information on risk to predation. It has been shown that after the treatment fish aggregated and moved inshore. The change in fish distribution was clear only immediately after the treatment, fading away few hours later.
