											        				Haor is a wetland environment considered as a rich diversified fisheries resource with
important role on ecology, economy and social structure. The present study was
conducted to evaluate the diversity of fish and plankton communities in the
Kishoregonj haor, Kishoreganj, Bangladesh. Fish samples were collected from the
fishers and fish landing station for taxonomic study from July 2017 to December 2018.
Fish were identified through direct observation and using morphometric and meristic
characteristics. A total of 23 genera of phytoplankton belonging to 4 classes were
identified. A total 8 genera of Bacillariaophyceae, 9 genera of Chlorophyceae, 3 genera
of Cyanophyceae and 3 genera of Euglenophyceae class were listed from the study
area. In total 3 groups of zooplankton were identified, i.e. Phylum- Rotifera, OrderCladocera and Sub-class-Copepoda in Kishoreganj haor. In the present study, a total of
79 species of fishes belonging to 27 families under 9 orders were recorded.
Cypriniformes was found as the most dominant order comprising 31 species followed
by Siluriformes (21) and Perciformes (15). The result of this study showed that the fish
and plankton diversity indices in the Kishoreganj haor are good even some fish species
are gradually decreasing.
