P. Fischer et al., The use of passive integrated transponder systems (PIT) triggered by infrared-gates for behavioural studies in nocturnal, bottom-dwelling fish species, J FISH BIOL, 58(1), 2001, pp. 295-298
The movements of juvenile burbot Lota lota were monitored continuously with
an overall efficiency of 92.5%. The results show that passive integrated t
ransponder (PIT) systems (or variations of them) are highly valuable for be
havioural studies of small nocturnal fish species at the laboratory or meso
cosm scale. (C) 2001 The Fisheries Society of the British Isles.
