The phytoplanktons found in the Federal University of Technology Akure (FUTA) was studied from April to August 2017 which spanned for 5 months which took place in two sampling sites, the Fisheries and Aquaculture Technology Research Farm pond (FAT pond) was the first sampling station while Crop Science and Pest Management water body was the second sampling water body where samples were collected at different sampling depths ranging between 16-30cm. A hundred and fifty (150cl) of FUTA water samples were collected in each month throughout the study period.

Fourteen (14) species of phytoplanktons were identified as aggregate in the two sampling sites, consisting of Bacillariophyta (10), Chlorophyta (2), Dinophyta (1), Mediophyta (1). The total phytoplankton density in the Crop Science and Pest Management water body increased from a total population of 44 in the fourth month to a total population of 50 in the fifth month while in the Fisheries and Aquaculture Technology (F.A.T) pond the increment started in the third month with a total population of 41 to 61 in the fifth month. Temperature, pH and dissolved oxygen and conductivity ranged from 23.84°c to 29.40°c; 6.61 to 7.14, 3.08 to 5.35 mg/L and 106.18 to 195.78 µscm respectively. 

Navicular sp was the most dominant phytoplankton specie with a total of 120 observations followed by Coscinodiscus and Ceratia which occurred with 113 and 68 respectively while the species with the least number of appearances were Liemophora and Pinnularia with 4 and 3 occurrences respectively. 

Changes in temperature, conductivity, pH and dissolve oxygen had an effect on phytoplankton abundance resulting in an increase and decrease in the number of phytoplankton species. However, the result found cannot necessarily deduce the long-term biological events and processes of the water bodies. Since the study was done in a period of five months which is not sufficient for concluding the results.
