Fish Passage & Recent Projects

Fish Passage Devices include fishways, fish ladders, fish bypasses and fish lifts. We can recommend optimal designs and locations for Fish Passage Devices to suit site-specific and species-specific requirements. We can develop strategies and devices that allow passage of target species, while blocking passage of undesirable species such as sea lampreys and carp. We also monitor fish movements, activity and behaviour at migration barriers and we can enhance fish passage at existing structures.

Fish Movement Related to River Flow Reversal

Since 1994, we have carried out several investigations of fishways, as well as behavioural and physiological assessments of dam impacts on warmwater fish. Other work includes biotelemetry, habitat surveys, habitat use relative to availability, effects of fishing tournaments on fish, ecological studies of riverine and lacustrine fishes and other studies of interest to biologists, ecologists, fisheries managers, and regulatory agencies.
