Abstract

Abstract Mahseer fish or tor fish ( Tor sp.) are fish that migrate from upstream to downstream or vice versa. Knowing the habitat of Mahseer fish will provide information on how to manage these fish. The purpose of this study was to apply radiotelemetry to determine the migration of Tor fish ( Tor sp.). This research was conducted in the Batang Toru River, North Sumatra. This research was conducted by attaching a tracking device to the Mahseer fish ( Tor sp.) After which it was observed for 2 months. The results of this study indicate that there is an up and down movement as far as 300 meters from the release location of Mahseer fish.
