Twenty-four hours in the life of Zingel asper
For the first time, radio-tracking observations were made over 24 h cycles during the growing season to quantify the habitat use and home range of Zingel asper, a critically endangered fish species, endemic to the Rhône River with a high risk of extinction (IUCN). New advances in radio telemetry with regard to the size of tags provided an opportunity to collect behavioural and habitat use information while remaining non-lethal. Zingel asper was characterized by small ranges of habitat use and, contrary to previous assumptions, the species was diurnal as illustrated by a smaller home range during the night than during daytime.
