Abstract: The dynamics of plankton and the characteristics of water quality were investigated. The experiment was conducted in the nursery fish farm of Indra Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh during the month July to August. The sampling was done daily basis for 20 days during sampling Periods water and plankton sample were collected. Diurnal fluctuation of plankton was calculated from collected sample four times in a day. The total thirty-three algal genera were identified, of which seventeen were allocated to the Chlorophyceae family, nine to the Cyanophyceae family, six to the Bacillariophyceae family, and one to the Euglenophyceae family. When it came to phytoplankton, the Chlorophyceae group was the largest. Chlorophyceae members include Oocystis sp. and Tetraedron pseudosp. Was shown to be the most prevalent. The highest amount of daily variation was shown by Oocystis sp. Tetraedron sp. Spirogyra sp. Chlamydomonas sp. along with Mougeotia sp. When it comes to Cyanophyceae, Oscillatoria sp. alongside Aphanocapsa sp. was in charge. Microcystis sp. Oscillatoria sp. Anabaena sp. alongside Aphanocapsa sp. displayed the largest daily fluctuation. Nitzschia sp. is one of the Bacillariophyceae. along with Synedra sp. predominated. The highest daily variation was shown by Navicula sp. Nitzschia sp. Melosirasp. Protococcus sp. along with Synedra sp. Just Euglena sp. is found among the Euglenophyceae. was discovered. According to the study, the ponds' natural fish food organisms and water quality make them suitable for the growth of fish spawn.
