The ecology and behaviour of tigerfishes (Hydrocynus spp., Alestiidae) remains largely unknown despite these piscivores play a crucial role in tropical ecosystems. A 44-cm tigerfish H. brevis was equipped with two transmitters using accelerometer and depth sensors, the signals of which were simultaneously recorded while tracking the fish over four 24-h cycles during February and March 2001 in the River Niger near Bamako, Mali.
