Abstract

A one-year-long field survey had been conducted to investigate the seasonal fluctuations in the water quality properties and fin fish diversity at Hakaluki Haor, Bangladesh. Different water quality parameters and fish catchment data were taken from each site on monthly basis. Fish were identified in family basis through surveying in fish landing centre, fish markets and fisher’s community and samples were brought to laboratory for accurate taxonomic identification. Temperature, turbidity and pH were found to be different depending on season; while, dissolved O2 and NH3 were moderately uniform in all season. Almost twenty taxonomic families have been identified. Among them, the Cyprinidade family was the most abundant familiy (34%), following Bagridae (8%), Siluridae (6%); while, the Mugilidae (1%) was the least abundant one. The highest and lowest value in the majority of diversity indices were observed in monsoon and winter, respectively. The Pearson correlation test was conducted to evaluate the regression coefficient between different water quality parameters and diversity indices.
