Abstract
The distribution and abundance of zooplankton species of Harapan and Aman Lakes were investigated in relation to physical parameters and chlorophyll-a content. Both lakes were characterised by the occurrence of algal bloom problem. The composition of zooplankton was collected at monthly intervals from November 2013 to February 2014. The total number of taxa in Harapan and Aman Lakes were 23 and 27, respectively. Rotifera was the highest abundance group represent 64% of the total species recorded followed by Copepoda (29%) and Cladocera (7%). Three dominant zooplankton that been recorded in both the lakes are Brachionus forficula, Brachionus nilsoni, and Trichocerca sp. High abundance of these species indicates that the lakes are eutrophic water bodies. Overall, zooplankton species distribution and abundance in the study sites are influenced by various environmental factors such as water transparency and chlorophyll-a content.
Highlights
Zooplankton are considered as one of the most important food source to the aquatic organisms to planktivorous fish
Zooplankton community is the major route for energy flux in the plankton based food web causes them to become an important element in functioning of aquatic ecosystems (SantosWisniewski et al 2006)
The characteristics of zooplankton community structure are characterised by the intrinsic factors including surface area, depth, trophic level, colour of water, and the biological community of the lake (RahkolaSorsa 2008)
Summary
Zooplankton are considered as one of the most important food source to the aquatic organisms to planktivorous fish. The characteristics of zooplankton community structure are characterised by the intrinsic factors including surface area, depth, trophic level, colour of water, and the biological community of the lake (RahkolaSorsa 2008). These creatures can be a useful tool for the determination of ecological status of a lake. Zooplankton have close links with the surrounding environment throughout their life cycles and they demonstrate rapid changes in their populations when disturbance occurs such as eutrophication They are potential indicator species for water pollution (Jakhar 2013). We aim to establish the degree of association between physical environmental variables and the species abundance in the zooplankton assemblages
