Microalgae habitats can be found in almost all waters, including groundwater ponds. This study aims to determine the types of microalgae that live in fish pond waters in Pekanbaru City. Riau. This study uses a survey method, namely by observing and collecting samples from the waters of fish farming ponds that are assigned randomly from fish farming ponds in the Pekanbaru City area. Sampling was carried out at 4 stations, and at each station, there were 3 sampling points. The collected samples were then observed under an Olympus light microscope. This research was conducted at the Laboratory of Aquatic Biology, Faculty of Fisheries and Marine Affairs, University of Riau. The results of the study found 13 species of microalgae that live in fish farming soil ponds in the city of Pekanbaru. The 13 types of microalgae include Scenedesmus quadricauda, Pediastrum duplex Mey, Tetrastrum heteracarthum, Spirulina plantensis, Microcystis aeruginosa, Chlorella vulgaris, Scenedesmus dimurphus, Pediastrum duplex var, Closeterium parvulum, Coelastrum microforum, Scenedia pediatus and Scenedestrum acuminatus. Based on the abundance calculation, it is known that 316440 cells/L, and biomass 0.23 g/L. Water quality was recorded Temperature ranged from 28.5-29.33m oC, Water brightness ranged from 18.25-38 cm, pH 6.00, DO ranged from 2.45-6.53 (mg/L), CO2 Free ranged from 3.00 -14.98 (mg/L), Nitrate (NO3-) ranged from 0.1-0.3 (mg/L), and Phosphate (PO43-) ranged from 0.005-0.008 (mg/L).
