Abstract/ Executive Summary:

Wetlands are the most dynamic ecosystem play a vital role in indigenous fish production which is a main source of protein of rural population ultimately helps socioeconomic condition of the adjacent areas of inhabitants. Zooplankton is regarded as primary consumers of the water bodies and constitute the food source of fish and other animals..Attention has been given to the water body of Kotchandpur Baor and the growth, distribution and abundance depend on the status of water body. The work has been carried out during one year period from June 2011-May 2012 in different seasons viz. monsoon, post monsoon and pre monsoon respectively in order to asses water quality parameters and zooplankton diversity. During the investigation, zooplankton diversity was observed high in the wetland. Rotifers were the most dominant group followed by Cladocera, Copepoda. Protozoa and Ostracoda during the investigation. There is a high density of zooplankton in monsoon than compare to other seasons indicate good water quality and less pollution load.

Keywords: Ecology, Water quality, Zooplankton, Seasonal variations

Location: Bhabanipur, Balaramnagar and Joydea.

Start Date: 00-06-2011

End Date: 00-05-2012

Program Area: Conservation and Biodiversity

Commodity: Plant

Objectives:

The information regarding the faunal diversity of wetlands in south western part of Bangladesh is very scanty.A number of studies has been carried out on faunal diversity of different wetlands such as Sharma and Sharma (2008), Khan (2002 and 2003) .the aim of the paper was to estimate the species diversity of zooplankton in relation to water quality.

Methodology:

The work is the outcome of limnological analysis which was undertaken from June 2011 to May 2012. Sampling Sites: A.Three sampling sites were selected for the analysis of water quality and zooplankton. These were Bhabanipur, Balaramnagar and Joydea. Water samples were collected at regular intervals on monthly basis at 8.00 to 9.30 am from the different stations of the study area. pH, temperature were measured on the spot by Hanna device(pH meter) and mercury thermometer. DO was measured according to Wrinklers method. Rest of the parameters were measured in the laboratory as described by APHA1989 For the study of zooplankton, samples were collected on monthly basis for a period of one year i.e. from June 2011 to May 2012. 50 L of water was passing through conical shaped plankton net by towing and filtering of bolting silk mesh size No.25. Filtered water sample was immediately preserved in 5% formalin and was reserved aside in the laboratory for settling at the bottom of the pot. Supernatant plankton free water was released and dense samples were taken for investigation.Identification of different groups of zooplankton was done under an microscope with different magnifications using keys and monographs of Adoni (1985), Edmondson (1959,1974). Beside these, the specific books and literature were used for the identification of different groups of zooplankton viz Victor and Fernando, 1979, Reddy, 1994,Dhanapathi, 2003 and Michel and Sharma, 1988 .

Achievement/Findings:

From the above study, it is conclude that the joydea lake possesses large variety of zooplankton species. Beside these, large number of macrophytic population provide shelter, niches and food for aquatic animals.the pattern of zooplankton diversity indicates tropical characteristics of lake reported by Khan 2003. Invasion of water hyacinth creates major problems in aquaculture and hampered the zooplankton diversity, richness and abundance (Luken and Thieret,1997)
