Abstract: Babulu Laut Village is an area where there is a brackish water river that is used by local residents as a source of water for pond cultivation. Until now, there is no information about the types of brackish water fish found in the river. This research aims to find out the diversity of brackish water fish in several rivers in Babulu Laut village, sub-district Babulu, district Penajam Paser Utara (PPU), East Kalimantan. This research conducted on October-December 2021. Sampling used purposive sampling and random sampling methods at three research stations. Fish sampling conducted by installing gill nets for 2 hours with checking every 30 minutes and using fishing rods for 1-2 hours.
