The present study was carried out in different types of water bodies of Ludhiana (Punjab) to record the population density of cyclopoid copepods during the year 2015 (Jan-Dec). Identification and enumeration was done with the help of sedgewick-rafter chamber (S-R cell). Maximum population density of cyclopoid copepods i.e. 1664.00±3.6/L was observed in the month of August in GADVASU fish ponds followed by Atta village pond i.e. 603.00±7.9/L observed in the month of September and least population density was observed in paddy fields when compared with other water bodies, whose maximum density was recorded in the month of September i.e. 64.33±0.33/L. Growth of cyclopoids were maximum in summer and minimum in winter which might be due the fluctuations in light intensity and temperature, in turn affecting the food supply of zooplanktons
