We recently tagged an arapaima with a fastloc-GPS tag. Data are coming in!
We have just initiated our arapaima and arowana telemetry work in the lower Purus River! Fish were tagged with radio (arapaima and arowana) and acoustic (arapaima) tags from November 2 to 9, 2014. Photographer Adriano Gambarini documented our work. Click here for story published on the G1 website (in Portuguese).
