MORPHOLOGICAL CHARACTERS OF FRESHWATER STINGRAYS (CHONDRICHTHYES: DASYATIDAE) IN MUSI RIVER, PALEMBANG CITY, SOUTH SUMATERA PROVINCE

A study to determine morphological characets of freshwater stingray in Musi River of South Sumatra Province has been conducted from June to December 2020. The fishes were collected in Musi River where located at middle of Palembang city. Collected specimens were preserved to Animal Ecology Laboratory, Department of Biology, Faculty of Mathematic and Natural Science of Sriwijaya University.
