Abstract

ABSTRACT The largest lake on the island of Bali is Lake Batur. Fish diversity in Lake Batur is still not well understood. In order to offer correct information on the diversity of species that occur there, this research intends to update the record of fish diversity in Lake Batur. Over the lake area, observations were made at five stations throughout the dry season of 2022, which ran from August 30 to September 5th. Nine indicators of water quality were measured across all stations. In order to gather samples, fishing rods, communal 2-3-inch nets, experimental gillnets with a mesh size of 1 inch, and scoops were used. For the purpose of identifying the species, all samples were kept in 10% formalin. There were 1,104 fish samples from the lake. Abangsongan Station 4 has the most fish. The outcomes demonstrated that the water is still of acceptable quality up to the seichi disk depth. 17 species were present, which were split into 14 genera and 9 families. According to this study, Lake Batur has a remarkable diversity of fish, including climbing perch (Anabas testudineus), snakeskin gourami (Trichopodus pectoralis), and blue gourami (T. trichopterus) and beardless barbs (Cyclocheilichthys apogon), all of which were previously unknown. The Asian swamp eel (Monopterus albus) and milkfish (Chanos chanos) were not discovered, and several scientific names are inaccurate.
