Production, biomass and productivity of the microcrustacean zooplankton populations of three low-land reservoirs, Tissawewa (eutrophic), Ridiyagama (moderately eutrophic), and Muruthawela (mesotrophic) in South-east Sri Lanka were studied. The temporal variation of zooplankton production was studied in Tissawewa on basis of fortnightly sampling on five fixed sampling stations for 2 years. Zooplankton production was relatively high, mainly because of high copepod production predominantly realised due to two calanoid copepods, Phyllodiaptomus annae and Heliodiaptomus viduus. About half of the copepod production was contributed by the naupliar instar stages, whereas the contribution of the eggs was generally much smaller (
